It’s the naked GSX-R1000 K5 we all hoped it would be. The GSX-S1000 is fast, fun, agile and cheaper than its rivals.
- Latest: 2021 Suzuki GSX-S1000 review
That iconic long-stroke engine has the K5’s distinctive growl and wide spread of power. For 2017, there’s more power and torque: 148bhp (up from 143) 79.6ftlb (up from 78.2ftlb). They have also added a slipper clutch and other small aesthetic changes.
Ride quality & brakesNext up: Engine
The cast aluminium frame is actually lighter than Suzuki’s road-going superbike, but it has a longer wheelbase and lazier steering geometry for stability on the road. The aluminium swingarm is lifted straight from the GSX-R1000. Kerb weight is 207kg and 209kg with ABS. The GSX-S1000 is agile, confidence-inspiring, stable and the Dunlop D214s offers good grip for fast road riding. Forks are 43mm fully adjustable KYB items, but the single shock is adjustable for rebound and preload only.
There are no problems with ride quality, but it doesn’t offer the plush, sophisticated ride of more expensive suspension set-ups. Brembos are lifted from the GSX-R1000 and provide ample stopping power, but lack bite.
EngineNext up: Reliability
Powered by the now almost mythical long-stroke GSX-R1000 K5-K8 motor, Suzuki has made a host of detail changes to make it even smoother and more tractable, including 3% lighter pistons and rings than the original, re-profiled inlet and exhaust cams, a new airbox, 4-2-1 exhaust, curved radiator and long-nose 10-hole injector nozzles. The motor gurgles and growls through its rev-range, and has a long spread of power and a decent top end hit. But the power delivery is snatchy from form a closed throttle at low speeds.
This was the second Suzuki road bike to be fitted with traction control – the V-Strom being the first. TC has three stages and can be switched of completely. Analysing data from wheel-speed, throttle, crank and gear position sensors, the ECU makes 250 calculations a second. It retards the ignition and closes the secondary butterflies to control wheel slip.
And in 2017, the GSX-S got another 10bhp and more torque (up to 80ftlb at 9500rpm).
Reliability & build qualityNext up: Value
There are lots of nice touches, like the chassis and brakes from the GSX-R1000, traction control and the full LCD dash. The mechanicals are all tried-and-tested so won’t give you a problem, but Suzuki paint finishes can be notoriously thin. You’ll need to pamper it if you plan to ride through winter.
Value vs rivalsNext up: Equipment
The GSX-S1000 is cheaper than its Japanese rivals, like the Honda CB1000R, Yamaha MT-10 and Kawasaki Z1000 and much more affordable than the likes of the BMW S1000R, Aprilia Tuono V4R and KTM 1290 Super Duke R.
It’s the first full LED dash fitted to a Suzuki. It features all the information you need for the road, including rpm, speed, TC information, a gear position, clock, fuel gauge and trips. A comfy riding position is topped off by a set of tapered aluminium Renthal Fatbars. But the Suzuki is built down to a price and doesn’t come with all the latest electronic rider aids, fully-adjustable suspension or current-generation sports tyres.
A slipper clutch was added in 2017 to make downshifts smoother.

Version: 2020 Triton Blue
Very Good overall, another few tweaks and it would be a 5 out of 5 bike. The on off throttle does take some getting used to, it should have LED lights all round for the last upgrade and back tyre should be a 55. I would recommend this bike because I've tidied it up and done the upgrades and now it's as close to perfect as possible
Ride is very good and even better after fitting a 55 rear tyre. Brakes could be alot better and upgraded lines are expensive
Revs very well, loads of power but it is very snatchy and you do get used to it but a nice smooth throttle would have finished the bike off Do the after market upgrades and it definitely helps
You can see it was used through winter, so alot had to be spruced up
Servicing is fine if you do it yourself, especially when out of warranty
Screen is basic and does have alot going on, colours would have helped separate it Put better tyres on with a 55 rear, engine upgrades and a good screen
Buying experience: Bought at a distance from a Harley dealership, disappointed with them but that's another story.
I’d recommend it to anyone who doesn’t ride far, but loves sharp handling and mad acceleration
Needs a better rear shock to compliment the front shock that have 3 way adjustment
Can’t beat it amazing power delivery with blistering acceleration
Pretty good, although the over use of plastic fasteners is annoying
I would say this is average for a modern bike, but I prefer to service bikes myself once out of warranty
Very basic, but perfectly acceptable for a street bike
Buying experience: Poor, only test ride was on the day of purchase, bike shops are still decades behind car dealerships
Annual servicing cost: £265
Not far off brilliant for a street bike
Needs a more adjustable rear shock
Excellent power and acceleration
It’s a street bike so you don’t expect much
Buying experience: From the dealer, only had 156miles on the clock and cost just over £8000
Fast, reliable, light and easy to handle, great value.
I changed the rear shock as I only ride solo and the spring rate was too high, front forks adjusted to suit and the bike is now very comfortable, seat maybe a bit soft.
Had the dreaded euro4 throttle snatch/low speed fuelling problems ironed out with a Woolich remap. Bike is now much smoother at urban speeds and pulls hard from 2500 rpm.
Totally reliable and no signs of rust or corrosion.
Not had it done at a dealer, oil and filters is dead easy and only £40 DIY job, will have a major valve service at the dealer though. 50+ mpg nearly always.
ABS standard and 3 way traction control, no IMU or multiple rider modes etc, plain simple and easy to understand.
Buying experience: Bought from a dealer for a competitive price.
Annual servicing cost: £100
Comfort, handing, brakes and steering. Too much info on the dash for a given setting. Hard to read the speedo which is obscured by my chin bar! Shadows caused by the proximity of the stacked headlights but riding on dark country lanes is okay. It's a bike I would recommend.
Great handling but the Roadsport 2 tyres seem to prefer it dry. I'm looking forward to longer journeys as the bike feels very natural to ride.
Smooth, responsive and great engine braking. Lovely exhaust note. Plenty of torque in 4th and 5th.
I've done thousands of miles on Suzukis and I've found them very reliable. I'm lucky to have B&B Suzuki as my main dealer and I put my trust in them.
About 40mpg but service intervals are 7 thousand miles
Great response from a very agile machine. Riding modes and quick shifter are welcome. I'd prefer a couple of separate position lights to give the bike a wider profile in oncoming traffic.
Buying experience: I part exchanged against a low mileage bike for £10,000.
Annual servicing cost: £150
this is my second (after the first was written off in a smidsy) and after 5 months with a tuono v4 1000 that i never clicked with hopping back on this was like coming home. yes the throttle is a little bit snatchy sometimes but you get used to it (or get it mapped out) and yes the suspension is a little bit bouncy but a lot of it can be dialed out setting it up properly or you can upgrade it and still pay less overall than anything European. the electronics (as few as there are) are all that's really needed for the road and always get turned if you're going on track anyway.
suspension could be better but is not as bad as some would have you believe and there are plenty of options available to improve it.
i wont repeat all the gushing reviews about the engine, but they're true
my first one (2016) chewed up the gearbox but I've not seen or heard anything suggesting any common reliability issues and that gear box was replaced under warranty.
a little lacking compared to many of it's rivals but the only thing it really needs is ride by wire throttle to enable up and down blipper. there's no need for hundreds of different settings when most people I know will find a standard setting and never touch it again. the brembo brakes are nice but it is lacking braided lines and its a fairly pricy upgrade for ABS models.
Annual servicing cost: £150
Poor standard suspension
Brilliant performance, delivery can be poor when coming back on the throttle
Hugely underrated bike
Guessing, 1st service done when I bought the bike
I don’t want gizmos , just a good engine and decent handling
Buying experience: Dealer ex demo, great price, decent sales department
Annual servicing cost: £300
The bike's handling can't be faulted. On its Michelin Road 5s its planted to the point it's like being on rails cornering. Bars are at the perfect height so you don't have to bend to reach. Comfortable for long miles. Good range on tank. The only negative, I got it second hand with a tail tidy. This causes surface water to find its way up your back. An extended plastic piece bolted behind number plate saves damaging leathers or Gore tex suit.
It runs well in all weathers, no noticable difference between good or poor weather. The sit-up stance suits my needs perfectly, gone are the days where my head is the same plane as my backside. Too old and decrepit now. Brakes stop the bike on a sixpence.
I had issues for a while with a snatchy throttle at low revs. Was thinking an ECU flash or Power Commander would be needed but I had the TPS (Throttle Position Sensor) adjusted to centre and it totally transformed it. The bike responds immediately to a twist of the throttle but with close to 150bhp I wouldn't expect anything less.
Build quality is fine. I put just shy of 13,000 miles on it last year in pursuit of an achieved Advanced First via IAM, in mostly atrocious weather. Never missed a beat and still comes up like a new pin with nearly 25k on clock. I get it serviced at the correct intervals through Lee's Motorcycles, Ledbury. The attention to detail with them is second to none.
Service costs are very reasonable and far less than a main dealer. Tyres aren't a cheap item but I get a good mileage return on them. I also get close on 50mpg which is pretty good in my eyes.
I like every aspect about it. Suzuki have totally nailed it. A naked with a proven K5 engine from the legendary GSXR, sportsbike performance in a comfortable package.
Buying experience: It was 18 months old with 3,500 miles on it when I purchased it from a very good dealer. They even replaced a rear tyre without being asked, impressed. I chopped in a 2016 MT 07 for the GSXS1000S. It was listed at £7995 but I got a very healthy price for the Yamaha which had 11,200 miles on it.
Very good well balanced bike that can surprise a few more expensive models
Rear end gets a bit twitchy however the front always seems well planted and inspires confidence.
Great engine with a fantastic soundtrack.
Good value naked bike
First service seems expensive, perhaps I’m a bit out of touch. I was charged £48 for cbr1000rr fire blade in 2017. Checked most local Suzuki dealers all quoted £220 - £245.
Mirrors move about a bit - one set replaced under warranty.
Buying experience: Dealer was very good all that was promised was provided on time
Annual servicing cost: £150
Excellent K5 engine, chassis turns well, standard suspension is ok, brakes are fine 99% of the time. I’d recommend the GSXS such good value for money and if you want to upgrade some items it still represents good value.
I have replaced the rear shock with a Nitron R1 and had custom springs and oil in forks. The original set up was ok but too hard for me on the majority of B class roads I ride on - I needed something more supple. MCT did a great job fitting and tuning the suspension. Brake pads were replaced after fading and fading in March 2020 (heavily glazed).There was an improvement with new pads but I experienced brake fade again so dealer replaced with EBC pads, now much improved braking all round
Super engine, love its flexibility. I can leave it in 3rd gear for spirited riding in twisty(flowing bends or work it harder using the gear box more getting even more vicious acceleration.
Build quality seems fine no reliability issues. First Suzuki I’ve owned. I always treat my bikes with ACF 50 which stops corrosion. I’m always impressed with Japanese build quality, friends I ride with have European hypernakeds and are always mentioning irritating niggles ie fuses blowing, bolts rattling loose.
Original Dunlop 214 replaced at 2000 miles, hoping the Sportmax 3 will last longer.
Love the engine and chassis. Handling now improved with suspension upgrades and brakes (my choice not absolutely necessary). The electronics package is basis along with the dash compared to other super nakeds but this doesn’t bother me.
Buying experience: Bought from CJ Ball for £10399. A few extras thrown in! Always good service - I’ve bought many bikes from here.
Version: Z (blacked out)
Annual servicing cost: £200
I made it into a 5 out of 5 by using PC V to fix on/off fueling mid corner and snatchy throttle improved also. Out of sight smoothness with G2 throttle tamer fitted. Also R11 Exhaust fitted. The initial price paid made these mods feasible although on new bike one shouldn't have to. Tight Euro 4 emissions are mostly to blame it appears as changed fueling + milder throttle cam fixes all.
There good but fluid lines and master cylinder could be improved. Better pads are apparently the go but haven't felt the need so far.
Arguable the best R motor ever with improvements.
Mostly due to the bullet proof k5-8 motor. Suspension is adequate set up tight for speed preferably. Paint is as they say a bit thin.
Estimate as i do most of the basic work.
The TC is excellent, apart from the blinking light you would know it's intervening.
Buying experience: Dealer about 9000 pounds with Tail tidy and Yoshimura fitted.
Annual servicing cost: £170
I would describe the engine like a boiling kettle with the throttle being very responsive from closed, stock exhaust sounds good and looks good, brakes also good,smooth gear changes and excellent lighting for night time riding, good seat height for shorter riders, mirrors good. Vibrations in foot pegs at motorway speeds and twitchy throttle but no big deal. I would recommend but for novice riders
Comfy seating position.
Cracking engine but very buzzy more like a 600, i.e. R6.
Solid engine can’t fault it, but well looked after.
You get an excellent bike for the money.
I think it is an excellent bike and I can’t really fault it, especially for the price, if I really had to fault it, it would be the shorter gearing, as I am used to supersports bikes but I am getting used to it. Like I stated it’s like having an R6 instead of an R1 but the high revving engine gives this bike character.
Buying experience: Purchased from a dealer as new in a part exchange for an R1. Bought on a PCP deal with low interest rate.
Version: GSXS non abs naked
Annual servicing cost: £100
Loads of down low torque and absolutely screams over 8k. Handles twisties quite well but rear shock needs work!
Replaced pads with EBC HH race and huge improvement. Stop pads feel spongey and I highly recommend going to steel lines or new pads.
Flawless! Bike is mental and for street riding she does not need any more power!
So far so good. Put 4,000 miles on it.
Fitted bike with full M4 exhaust, bmc race filter, and PC5. After proper tune on dyno abrupt throttle snatch was better but still super sensitive. After a couple hundred miles you will be adjusted to it.
Buying experience: Paid 6999 US from dealer with 2XXX miles on it.
Annual servicing cost: £230
the motor /gearbox /clutch is a1 but the suspension very ordinary the brakes are so-so (rubber lines ) its very comfortable great town bike but on the open road the handling not very good plus its got no soul the tuono 1000 (2008 ) runs rings around it lucky I keep the old tuono and save to buy a tuono v1100 aprilias are much better bikes plus they great to ride and have so much soul. i
the suzuki best around town
they got it spot on pity about the rest of it
mechanically a1 paint etc very average
dash very easy to see use functions
Buying experience: pretty good
Annual servicing cost: £300
Power everywhere, mental from 8000rpm. Throttle was an issue at first
ABS is a little early coming in, ditch the Dunlops and fit something else
Initially throttle was so abrupt it was ruining the bike but as the bike and I put on the miles (3000 now), it seems to have become less of an issue. It takes off like a scalded cat and the top gear acceleration is stunning
7500mls between services
just the right amount of electric gizmos, Michelin Pilot Road 3's 32psi front & 36psi rear will transform the bike's handling on the open road. Ignore Neevsey's score of 3 stars, it has everything you will ever need equipment wise, unless you are a spoilt bratt, the traction control is ace. BDS Peterborough to an ECU re-flash for £325+vat which will cure the throttle issue should you feel the need.
Buying experience: bought from a dealer Single Tracker at Crewe, ex demo with 250mls on the clock £8250, but I got it for £8000.
Annual servicing cost: £140
This model still has an issue with it's fueling, supposedly corrected with an ECU update in 2016 yet it's still awful! Uneven running from 1500 to 5000 Revs, snappy inaccurate throttle response and inconsistent engine braking. Suzuki should take this model off of the market until it's been properly corrected. Dealer is filing a technical issue with Suzuki I'm fighting for my money back!
Only any good above 5000 revs and constant acceleration so only good for riding fast, no good for normal commuting in traffic. Advertised as a 'Street' bike yet awful for every day street ridding! Brembo front brakes good enough.
Fueling issue leading to uneven shaky running at consistent speed, power delivery very sharp yet surprising as it go's from too lean to Rich. Once past 5000 revs power delivery is smooth and consistent.
Only the first 600 mile service completed at the above price. Good Mpg yet that's not surprising as it runs to lean up to 5000 revs. Value rating is marked down as it's not fit for purpose, as in not a good 'Street bike' and should not be on the market!
As standard you get TC with three setting's (pointless) and ABS which I'm also not convinced about. Standard tyres are OK - Dunlop 214 OM spec yet not comparable to current market tyres and will only last 2000 miles.
Buying experience: Bought from a Suzuki dealer Good, price due to it being pre reg.
Version: GSX-S 1000 ABS
Annual servicing cost: £200
Quick, very quick. Comfortable with great responsive handling.
ABS system is subtle. I don't know where the "lack bite" comment comes from in the MCN review?
Over 5000 miles in 11 months without issue.
Purchased a service package from my dealer. Bit of an outlay initially but will pay dividend in long term. Will get at least one valve clearance check in the duration of the package.
ABS and Traction Control. All this bike needs. Others have too many gizmos that will cost when they fail as the bike ages.
Buying experience: Purchased through Thunderoad Cwmbran. Quality outfit.
Annual servicing cost: £300
Excellent all round comfortable sports bike and exceptional value
I fitted a nitron r1 shock which has transformed the handling and ride comfort on bumpy dorset roads. 410 pounds fitted. Standard brakes very good once bedded in. I fitted metzeler m7rr's and went up to a 190/55 on the back which has made turning in a breeze it rolls beautifully into corners and holds it's line rock steady. Fantastic handling!
Stonking K5 power with top end giggles! Slightly vibey at around 7k after that it smooths out. Ride it in 3rd and 4th gear and hit the 8500 rpm take off on the straights roll back for the corners drive back out of them hardly any braking required. Hits over 140 mph on 4th gear. Just a complete hoot! Absolutely love the engine.
Lovely grunt K5 engine with top end rush which is addictive. I fitted a power commander which cured the snatch throttle and gave me a midrange boost
Comprehensive info and switchable traction control. Very comfortable seat. I have upgraded the screen which cost sixty quid very good protection now. I ride it everyday all weather's into work.
Buying experience: From robinsons in Rochdale fantastic deal at 8500!
Version: s1000 no ABS
Overall an EXCELLENT bike that won't break your back or your wallet at $9999 USD! High points: Very fast bike, light weight, nice gauge features, very comfy, turns into the corners like butter (after a small suspension tweak), seat feels good, exhaust loud enough for stock, good MPG, great riding position. Down falls: mirrors are worthless, and throttle is VERY snappy. I found it helpful to fix the slop in the throttle by tightening the throttle cable. Once you dial in the suspension settings it's like riding a magic carpet as you bang the gears through the twisties ! YEEEAAAAA BOOOOOYYY
Once you set the suspension for your weight and to your liking, you will unleash a whole new bike. I am used to RR bikes but this GSX can carve the corners just like the others. The brakes are excellent. You will be able to ride ALL DAY without stopping....until you need gas lol.
K5 engine....need I say more?
great Suzuki fit and finish, as always !
A litre bike for $9999 USD you must be joking!! Even the damn 600RR bikes are $13000!!! THIS BIKE IS A STEAL....
The gauges on this bike a pretty good. And THANK GOD it has a gas gauge. My only gripe is not having luggage bags....something I will need to buy ! Possibly a windscreen as well.
Excellent...Its been a long time coming and what a machine!!
Only 4 out of 5 because of the lack of adjustability on rear shock. Otherwise excellent on the road. Rolled preload off both front and rear. dropped a couple of clicks on comp and rebound damping. So much nicer to ride now. Brakes, very good once bedded in. Rode all day for 7 days, no major issues with bike. All day comfort, plenty of leg room for a 6 footer.
Awesome! More than enough power. Keeps up with BMW S1000R no problem. Averaged 55mpg around europe for 2300miles. Used at least 10% less fuel than BMW S1000R on same journey. Pulls from tickover in top gear. Smooth until high rpm, then a little viby.
No problems having now done nearly 3000 miles. Paintwork, general fit and finish is excellent. Stainless steel fastening everywhere.
Very good euipment but needs ambiant air temp gauge. unless you know where they have hidden it?!!
Buying experience: Bought from dealer Bill Smiths in Bangor, North Wales at listed price. Very happy with part ex they gave me. Very very happy.
