2015 Suzuki GSX-S 1000 - long term review

The first full day of ownership - arty shot along our street.... October 2015

Rather atypically for me, the GSX-S was something of an impulse purchase.  My much-loved 675 Street Triple had racked up 70,000 trouble-free km.  I needed a reliable bike for my work with the Institute of Advanced Motorists and almost subconsciously, I guess that my thoughts were turning to replacing it before too long.  The replacement was a no-brainer - the long-awaited 765 Street Triple.  Trouble was, despite lots of advanced publicity, the replacement for the 675 still hadn't been released on the market.

I happened to be in Auckland one day and called into a dealer who sells both Triumph and Suzuki brands. There was a demo GSX-S outside and the salesman offered me the chance to take it for a ride.  Be rude not to accept, wouldn't it?  The 1 hour ride through town and up the motorway was not unlike riding the Street Triple in those environments.  The new price was attractive so a deal was done.

A distance of over 45,000 km has now been covered and a tad over 3 years later, I still have it and there have been numerous posts about it on this blog.  At fairly regular intervals, I've been asked the question "Do you like it?" or "What do you think of it?"  That's a question which needs qualifying and I suspect that most riders have the same view about the bikes they've owned.  The answer isn't a simple one so this post is a sum of my experiences and thoughts during ownership.

Broadly, there were two factors involved with its purchase.  The first was "fitness for purpose".  What constitutes a good bike is a highly personal one based on individual needs.  In my late 60's at the time of purchase, 172 cm (5' 8") tall and weighing 74 kg , I wanted a bike which was relatively lightweight and had a modest seat height.  It also needed good performance and handling for my IAM coaching and a range of at least 250 km on a tankful of gas as a nod towards the relatively remote location where we live.  Didn't want to be gassing up en route to the nearest major population centres.  I didn't need to worry about a pillion as my soulmate prefers comfort with a roof over her head these days!  The GSX-S specifications pretty much ticked all the boxes.

The second factor is emotional appeal.  That's a pretty subjective topic and very hard to quantify.  The best example I can give is when I bought the Street Triple in 2009.  On paper, the Thruxton Bonneville, Ducati Monster 696, Speed Triple and Street Triple were my choices in that order.  They were then all ridden. However, literally within minutes of getting on the  Street Triple, it was a case of "I want it, and I want it NOW".  Handling, ergonomics, performance, induction roar and God knows what else all added up to something irresistible.  Totally smitten!  With the Suzuki, I was in too much of a hurry to get a new bike and largely overlooked how powerful emotional appeal is.  Immediately liked the Suzy but didn't love it.  A telling feature is that I used to pat the Triple when walking past it in the shed.  Have rarely done that with the Suzuki.  

Multi-function instrumentation - just 197 km on the odometer

I'm not big on adding farkles to my bike unless there's a genuine reason.  Don't like obtrusive, noisy exhausts so no aftermarket muffler.  Bought a small Suzuki screen for marginally better protection at higher speeds but mainly because it tidied the front of the bike and I was offered a great price at the time.  Had matte 3M clearfilm applied to the paintwork where there was a risk of stone chips or rubbing.  Crash protectors because they made sense.  Carbon front fender extender to reduce crap and stones from coming into contact with the radiator and front of the engine.  Replace crap headlight bulb with Ring Automotive +130 Xenon bulb, based on my past experience on 1600 km in under 24 hour (Iron Butt equivalent) rides on various bikes.  I also chucked on a set of Oxford expandable throwover bags to carry miscellaneous gear.  I won these in a raffle several years previously but had been unable to use them on the Street Triple because of the high level mufflers.  No heated grips as I use heated gloves on really cold days.  They keep the whole hand warm.

The break-in period generally doesn't reveal the total character of the bike but a couple of things stood out. The OEM Dunlop D214 Sportmax pure sport tyres were totally unsuitable for NZ conditions. Black mark for Suzuki.  In warm and dry conditions, grip was acceptable, even though the traction control light flickered on and off in rain mode. In the dry???  It was also easy to run right off the edge of the tyre in tight bends. Why oh why fit a 50 profile rear?  In cooler, wet conditions, the grip was so bad that it bordered on lethal.  Simply couldn't get enough heat into them.  To use a heartfelt profanity.... fucking awful things. The rear tyre had virtually no tread left by 3700 km.  You'd end up bankrupt constantly replacing them. Good riddance to them and the replacement was a 55 profile Pilot Road 4 which dramatically improved the handling.

The destroyed D214 - 3700 km from new

Compounding the grip issue was a severe snatch on a trailing throttle when cracked open. It made negotiating wet intersections and roundabouts an interesting experience on occasions!  The demo bike didn't seem to have that problem but maybe it was due to the shortish ride in that particular environment.  However, with the break-in period coming to an end, it was becoming a major distraction and from the GSX-S owners forum, it was clear that others were experiencing the same issue with a range of solutions being tried. The snatch was so distracting that consideration was given to getting rid of it but a polite and constructive email was sent to Suzuki NZ, expressing disappointment and asking for their comments.  Suzuki NZ had race-prepped one for US journalist/racer Don Canet when he was visiting NZ so I knew they had a good knowledge of the bike.

The following day, there was a reply email apologising for my experience and that if I arranged a time with my dealer they would fit a different ECM at their cost.  This was duly done and the bike was transformed.  Whether anything else was done at the same time I don't know but it was now an absolute pleasure to ride - kudos to Suzuki NZ for their proactive stance.  I might also mention that they also said that if I wanted to come along to a Suzuki track day, I could take out Don Canet's race-prepped bike!  Incredibly generous offer but having never done a track day at that stage, coupled with a bike on slicks, race pads and a footpeg height unsuitable for my ageing body, it was graciously declined.  Kudos to Suzuki NZ for their fantastic customer response though.  Why isn't everyone like that?


Loaded up for a few days away from home

Ergonomically, the bike is extremely comfortable.  The standard Renthal bars are perfectly positioned for me and the standard seat is good for 700 km days without too much discomfort.  However, I have knee damage from sports injuries sustained in younger days and the footpeg position caused severe knee ache towards the end of a full tank of gas.  This was completely solved by fitting some modified Buell pegs which drop the height by about 20 mm.  Brake lever position and brake light switch required repositioning but it only took a couple of hours at most to do the whole installation.  Beautifully modified by Joe Satterwhite from the US Hayabusa forum and made the world of difference.  Left the "hero blobs" off and even on a couple of subsequent trackdays, nothing touched down.  

Lowered footpegs - modified Buell

At 209 kg with a slightly less aggressive geometry than the 179 kg Street Triple, it's not as quick handling in the tight stuff but it's still good.  Turn-in has been immeasurably improved by fitting a 55 profile rear tyre as opposed to the OEM 50 profile D214.  The suspension out of the crate was too harsh front and rear for my 74 kg weight (in my socks, that is!).  That adversely affected the handling on bumpy roads.  Rear shock preload was ok but compression and rebound damping needed easing off.  Ditto for the front forks including backing off preload a touch.  I was fortunate enough to attend a suspension course early this year with international guru Dave Moss.  It included a 150 km ride, stopping periodically to make adjustments whilst the suspension was up to operating temperature.  He backed off the stock settings even more than I had originally done and it made a BIG difference.

Dave Moss tweaking the front end of my bike

However, Dave made the valid point that there's only so much you can do with suspension that's been built to a budget price.  By 35,000 km, rear rebound and compression damping had noticeably declined.  Having fitted top quality shocks to my last two bikes, I was well aware how good the handling improvement was on those so fitted a Nitron shock, built to my specs. Didn't bother with remote adjustment as my riding loads don't vary by much.  Cost was ~ NZ$1200 delivered (US$790).  The difference was immediately noticeable.  The rear end stayed in perfect contact over some notorious local ripples caused by logging trucks.  A major safety consideration as well as a performance one.  Rear tyre life should appreciably improve too.  My Blackbird rear tyre averaged another 2000-odd km after the Penske shock had been fitted.  Standard front suspension is adequate but depending on how long I keep the bike, I might fit Nitron internals.

One final comment about handling.  In the middle of winter a couple of months ago, I had an incident which whilst alarming at the time, was quite reassuring in retrospect.   I was riding on a wet, twisty road which gets minimal sun in winter, with the traction control in rain mode.  Exiting a bend with only light acceleration, the rear of the bike suddenly snapped about 30 degrees sideways.  I countersteered and the bike snapped just as quickly back in line with absolutely no drama.  Suzuki have clearly worked on mass centralisation and that, combined with traction control seems to have made the bike very stable and predictable, even in a significantly adverse situation.

Nitron NTR R1 rear shock - seriously nice engineering

Ok, but nothing remarkable.  Have never had a close shave due to any inadequacy on their part but on my first ever trackday, I wasn't game to rely on them in late braking from speed down the long straight at Hampton Downs!  They seemed to lack real bite once hot.  The ABS works just fine though. On my Blackbird and Street Triple, I used EBC HH pads and was really impressed with them.  Put them on the Suzuki this year and noticed an immediate improvement, especially at the February trackday at the Bruce McLaren Motorsport track  at Taupo.  Extremely happy camper now!

Old geezer does a Moto TT track day

There isn't really much to say.  One litre capacity, around 140 horses at the rear wheel, 74lb-ft (100 N-M) of torque, true top speed of around 235 km/hr (145 mph).  Academic really and more than adequate in most countries where high speeds are frowned upon by the law and likely to land a rider in serious grief.  I've had it up to an indicated 230 km/ hr on the track and it got there pretty quickly.  A whole lot less on public roads and performance is more than adequate for my needs.

A rapid road ride with some of the IAM coaching team

In real world road riding, it's the torque /acceleration which is the most useful trait to make good progress and the engine which is based on the original 2005-8 GSX-R 1000 "torque monster" engine certainly delivers that.  Maximum torque is delivered at over 9000 rpm but it's still pretty useful below that.  I loved the Street Triple torque because it delivered about 90% of maximum torque at 4000 rpm.  In essence, a virtually flat torque profile and a great power to weight ratio which made snap overtakes easy, without having to dance on the gear lever. The GSX-S doesn't quite have the same profile but certainly nothing to complain about!

In terms of fuel consumption, between 260-300 km per tankful is achievable on everyday riding but of course, it depends on your right wrist.  You don't buy one for economy. The instrumentation shows around 5.5 lt/100km for much of the mixed environment riding I do.  I noticed at the last trackday I did that it was nudging 9lt/100 km!

Probably the most debated topic on any bike forum.  Everyone has an opinion and a favourite brand.  The truth is that most riders run out of talent before a modern tyre from any of the major manufacturers reaches the edge of its performance envelope.  The trick is in choosing a tyre which suits the riding of the individual concerned.  As an IAM mentor/Examiner, I don't often get to choose what weather I ride in so a sport/touring tyre covers all conditions.  The OEM D214 pure sport tyres mentioned earlier in the review were manifestly unsuitable as an all-round tyre.  For a number of years on several bikes, I've been impressed with the Michelin Pilot Road series, particularly for their wet weather grip.  I've had 2 sets of Metzler Roadtec 01's on the Suzuki and whilst they pretty much matched the Pilot Road 4 in the wet, dry weather performance subjectively felt a little more planted.  The Road 4's and 01 rear tyres lasted for around 11,000 km before being replaced.  That's fine by me and a whole lot different to the 3700 km life of the D214!  Currently on 55 profile Road 5's and performance-wise so far, they're a step up on anything else I've tried.  The high crown gives a rapid turn-in.  Wet weather grip has been sensational and I run out of talent before anything lets go in the dry.  They've made the Suzuki a really nice bike to ride in all conditions. 

Brand new Road 5 - soft compound outer edge layer clearly visible

At present, there's only one question mark hovering over a ringing endorsement of the Road 5.  The first rear copped a puncture at ~2000 km which was not repairable.  Its replacement punctured at ~4000 km which was repairable.  In the last few days, I got yet another puncture (slow leak from a small nail).  So that's 3 punctures in a bit over 3 months.  I'd like to think that it's sheer random chance as previously, I went for over 3 years without a puncture.  Hopefully, it's not a shortcoming in the tyre design for the conditions I ride in.

Standard of finish
I chose the matte grey metallic finish just because it was different from other bikes I'd owned.  After 3 years, the grey looks pretty much like the day it came out of the showroom, as does most of the bike.  Being a matte finish, it only gets "wash and waxed", no polish used.  Some paint is flaking off the bottom of the radiator end caps, exposing bare metal.  Not a big amount and easily fixed if I could be bothered.  A spot of rust on the mirror stalks but again, not a big amount and easily fixed.  Degreaser is used on the engine in the summer to get rid of molten road tar and the whole bike is occasionally sprayed with Muc-Off to bring it back to pristine condition - love that product.  Gearchange and brake levers have a few light rust spots due to the original thin paint wearing through but nothing serious.  Suzuki's have a reputation for having thin paint but I'm more than satisfied with its appearance after 3 years from new.

Chain and sprockets
At 45,000 km, the original chain and sprockets are still in excellent condition.  It's been lubed at about 500 km intervals or thereabouts with Tirox teflon-based wax and it's clearly effective.  I use a home made laser rig for front and rear wheel alignment.  Whether this has a significant impact on chain and sprocket life, I wouldn't know.

Crash resistance
More accurately, drop resistance!  Why is it that most of our accidents occur not long after ownership?  Rhetorical question - most likely because we're not totally used to their characteristics.  Only had one "moment".  Had owned it for a couple of weeks and exiting a gravel parking area, got caught out by the tall first gear and not wanting to gas it too much with all the loose gravel.  I was already leaning it over to join the main road and stalled the motor.  Short legs and down I went!  The R&G crash protectors did their job and the only damage was a slight paint scratch on the muffler end-piece.  Err......  it wasn't the only damage.  Ego damage was massive as I was doing some instructing when it happened.  The trainee had the good grace not to laugh at the bad language over the comms.

Apart from the initial problem with low throttle fuelling, no problem whatsoever.  Put in gas, change the oil and filter every 6000 km and have it serviced at the appropriate intervals.  Nothing vibrates, rattles or works loose.  Engine is turbine smooth.  End of story.  For cleaning and routine maintenance, I have an ABBA stand which allows both wheels to be lifted at the same time.  Handy for doing baseline suspension setup measurements too!

ABBA stand - easy to use and rock steady

Do I think that the GSX-S 1000 is a good bike?  Yes, it certainly is but it very much depends on what you want from a bike.  Is it good value for money?  Again yes.  For around NZ$17,000 (US$11,200, 8,700 UK pounds), you get a lot of bang for your buck.

Do I love the bike?  No, I like it a lot but I don't love it.  That's where the emotional appeal I mentioned earlier comes in.  In retrospect, I'd have been better off waiting until the 765 Street Triple came out and buying one.  Having said that, I certainly don't regret owning the Suzuki; it's been fun and still is.  Having ridden Triumphs in my formative years and successfully drag raced one, I'll admit to having an emotional connection to the brand, despite having owned several other makes in 55 years of riding.

What of the future?  Can't be absolutely certain but at 71 years of age, my time riding as an Examiner with the Institute of Advanced Motorists must be limited.  The amount of time spent on that activity is substantial.  It eats into time spent with the extended family as well as going out sea fishing on the boat with my wife.  We also travel and would like to do even more.  It's increasingly important to get a better life balance.  The Suzuki probably isn't the best bike for simply pootling about on and a lower seat height and/or lighter weight would be nice.  2019 should trigger a delicious search for a new bike with a new "fitness for purpose".  T120 Bonneville?  Maybe.  765 Street Triple, low seat version?  Possibly.  KTM 790?  There's a thought!  Something not yet on the market?  What to do?  Real first world problem, isn't it?

For anyone considering owning a GSX-S (naked or faired), the dedicated website forum HERE provides a wealth of information and the members are a great bunch who go out of their way to help.  In addition, one of the members, Phuket Paul; has built a magnificent website with just about everything you need to know about the model.  It's HERE .

Awesome day to go for a ride!

Addendum - March 2019.  Well the Suzuki has just been traded in after 3 1/2 years of ownership and 48,000 km.  The reasons why and what I've bought as a replacement can be found HERE .

Also, a review of all the bikes I've owned can be found HERE.


  1. A well written and thorough review! But not in the market for a bike...

  2. Thanks Richard. Nothing that knobbly tyres and an outrigger wheel won't fix for your riding conditions. Where's your sense of adventure? :-)

  3. Good review Geoff. I enjoyed reading it and I agree with most of what you say. For me on mine the combination of tricky throttle and harsh suspension meant that I couldn't bond with it as I'd have liked. You have greater staying power than me but then we knew that anyway!

    It's funny how bikes, more than cars in my view, generate that emotional bond which is difficult to describe but very real. Let me know when you do want to sell yours...

    Perhaps you'd like to have a spin on my Thruxton 1200 at the IAM conference in Feb - Just to see what you think you understand!

  4. Thanks Lee. Staying power is down to my Chief Financial Officer holding the purse strings, at least in part 🤣. Yep, that emotional factor is pretty genuine.

    Hahaha,thanks! Knowing you, the offer is mainly altruistic, with a splash of Machiavelli to drop me right in it!

    1. Quite Sir! You know me too well...

    2. It's your friends you need to watch more than your enemies 🤣

  5. Great review Geoff though I can’t imagine you using blue language, even if you just dropped your first love! ;)
    Clearly the Triumph bias is your Brit heritage coming out? My missus is one of you lot by birth but despite living here all of her life I can’t convince her to become a naturalised Aussie. More British than British? ;)
    That is a bugger with the flats. Bad luck hopefully but those tread cutouts look really deep. The punctures haven’t been in them have they?

    1. Hahaha - in a past life, I had to deal with pink-shaded union militants. I can curse with the best when required :-) . We became naturalised Kiwis in 1980 - felt right to vote with our feet.

      Yeah, sheer bad luck I hope. The first puncture was right in the edge of one of the rain grooves but the other two were in the full meat of the tyre - jury is still out on whether it's chance or a tyre problem. Slightly gun-shy at present because of our relatively remote location.

  6. Great review Geoff! But, like Richard, I'm not in the market for a new bike - the Connie only has 153,000 odd km on her...

    Re tyres: it seems that all manufacturers stuff up the OEM ones. The Connies Bridgestones were (and apparently they still are) crap!

    1. Hi Andrew and thanks! I normally keep my bikes for multiple years but I tip my hat to you!

      Agree with you. In the case of the OEM Dunlops, it borders on negligence.

  7. Well written review, Geoff. I am sure all things considered the Suzi did a great job so far. I still favour your Street Triple though, for obvious reasons ;-)

    1. Thanks Sonja! Yes, it's absolutely fine for its job. The Triple suited you perfectly - once ridden,never forgotten eh? There's a very strong possibility of another one gracing the garage in Coromandel in due course 😁

  8. Very thorough review Geoff. It is a good looking beast bit I guess being a Pom, you have the Trumpy love in your blood. ;)

  9. Thanks Dave. Actually, my first bike was a Suzuki and I've had more Jappas and Europeans than British bikes. However, the bikes which had the biggest emotional appeal (for quite different reasons) were all Triumphs.

    1. Lol. You must think I'm crazy....I posted a reply right away but when it didn't get published after a few days I decided that the "dog ate my homework" and put up another, more curt reply. :)
      I was just at the traffic lights next to a Speed Triple and they do sound great.

    2. Not at all Dave! It's really weird as that reply went into an "awaiting moderation" folder rather than the normal email notification. Have no idea why and I only saw it sitting there by chance. BTW, the next bike might come out of left field - I also like the KTM Duke 790!

  10. Did you consider the 750?

    1. Hi Anon,
      The short answer is no because I didn't even consider the 1000 properly. It was bought for doing a job and it's done it pretty well. However, the next bike will be chosen with more care to meet a different purpose!

  11. Hi Geoff, I lived in NZ from 1985-(Feb)2018 and followed your blog when I had my S3's ("R" + std) in 2014/5. You are quite possibly the only "stranger" (to me anyway) who gives a totally objective account of a bike !!! Anyway, here I am now, 67yo, living in Southern Spain, having moved here this year, with a 2015 Street Triple Rx in the shed, and also lusting after a 765. I was very surprised when I saw you bought the GSX, I will be less surprised when I re-visit this blog next year and see you with a 765 (or a KTM790). Regards and best wishes...Steve.

  12. Hi Steve, nice to hear from you. Thank you for your kind words. An engineering background helps with objectivity although if you spoke to my wife, she'd probably tell you that it was a curse :-) . I'm delighted that another person of "mature years" has hooligan tendencies with a Street Triple. A fantastic choice on southern Spanish roads. Some local Kiwi friends of ours have just been on a Royal Enfield tour in part of southern Spain and loved it. As you would have gathered, the Suzuki was somewhat of an impulse purpose. I don't regret owning it but I would have been better off waiting for the 765 in hindsight. Check in around September or October next year for the next thrilling instalment :-) .

    Safe travels and best wishes,


  13. Hi Geoff, I am going on a 2 week Italy trip in May 2019 with 2 kiwi mates. One is coming from the UK on his Ducati Monster 1000S, the other is hiring a Street Triple 765s in Nice. I was going to ride to Nice on my Rx but it's 6 days (there and back) on motorway so I changed plans and am now hiring a Ducati Hyperstrada 939. We will be able to ride each other's rental bikes so I hope to get a good idea of the 765 in those 2 weeks. I will send you my (hopefully just as objective) review when I get back. Steve.

    1. Hi Again Steve,
      Sounds like a great trip! I'd be very interested in a comparison between the 675 and 765 from the viewpoint of a current owner. You can find my email address on this blog and I'm really looking forward to your impressions!

  14. Hi Geoff

  15. Hi Saffron,
    Thanks very much for the post. I must,say that it came as a bit of a surprise as I just write for fun and don't worry what others think! Nonetheless, it was a very pleasant surprise. Best regards, Geoff

  16. Hi Great article. Can you remember the fork settings ended up at? I'm currently playing with mine and would appreciate any help you can give. Ride safe. Regards Richard

    1. Hi Richard and thanks! Sorry but all my measurements and settings went with the bike for the new owner when I sold the bike in March 2019. Every good wish in sorting it to suit your weight and road conditions. My preload and and rebound etc were substantially backed off by Dave Moss.

    2. Cool thanks yes i've heard of people backing off a lot. Thanks for taking the time to reply. Kindest Regards Richard

    3. Most welcome Richard - hope it all works out for you.

  17. great review! I bought one in September but haven't been able to ride it as I am yet to get my full license. On November 30th I will be able to ride it legally and finally take it out to longer rides. I do have a question about vibration/buzz on handlebars past 110 kmh - I get terrible buzz on the handlebars and on the right foot peg. Previous owner had installed bar end mirrors thus removing OEM bar ends. I bought weighted bar ends and installed them, hoping it at least reduces the buzz. For the footpeg, I am not sure what the fix would be. Any ideas?

    1. Thanks for dropping by Suleyman and I hope that you enjoy ownership! I didn't experience any significant vibration on mine so I can't offer any suggestions. It wasn't long after buying it that I put lowered pegs on it which didn't vibrate at all. Best wishes!

  18. Hello sir, I hope you are still doing fine. I will buy soon a GSXS1000 after owning a CBR1000RR. Your review helped me a lot to understand what the bike feels like and I think i will give it a try. Thank you very much for the effort you made to write this review and I can tell you that you have a very big fan in Morocco ! You are welcome anytime you want

    1. Hello and thank you for taking the time to write, it's very kind of you. I hope you enjoy the GSX-S 1000 and recommend that you take a test ride if you can to see if it "speaks" to you. It's very good value for money but for me, I found it lacked "character" after owning it for a little while. The Duke 790 which I now own makes me laugh every time I ride it!

      By the way, our daughter visited Morocco pre-covid and fell in love with your country.

      Very best wishes,



  19. Hi Geoff,
    Can you remember what sort of footpegs you fitted to the GSX? I bought a Katana and I miss the footpegs from my Blackbird which were lower and more comfortable.

    1. Hi Anon, the pegs were modified Buell ones. There's a separate article on them in the blog. They were made by Joe Satterwhite from the Hayabusa forum. I bought my Blackbird lowered pegs from Jaws in the UK and was very happy with them too.

  20. Thanks for this impressive article. Personally, I also like 2015 gsx s750 as well.

    1. Thank you for the kind words! I think that a light, smaller capacity bike (like a 750) is all most people need. Kenny Roberts once said that he preferred the GSX-R 750 to the 1000 version for road use as he could use more of the power. If he said that, it speaks volumes for the rest of us!
