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.

4 out of 5 (4/5)

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.

4 out of 5 (4/5)

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).

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.

4 out of 5 (4/5)

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


3 out of 5 (3/5)

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.

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.

Equipment 4 out of 5

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.

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.

Ride quality & brakes 5 out of 5

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.

Engine 5 out of 5

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.

Reliability & build quality 5 out of 5

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.

Value vs rivals 5 out of 5

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.

Equipment 5 out of 5

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.

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.

Ride quality & brakes 4 out of 5

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

Engine 5 out of 5

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.

Reliability & build quality 5 out of 5

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.

Value vs rivals 4 out of 5

Original Dunlop 214 replaced at 2000 miles, hoping the Sportmax 3 will last longer.

Equipment 4 out of 5

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.

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.

Ride quality & brakes 4 out of 5

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.

Engine 5 out of 5

Arguable the best R motor ever with improvements.

Reliability & build quality 5 out of 5

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.

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.

Value vs rivals 5 out of 5

You get an excellent bike for the money.

Equipment 4 out of 5

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.

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.

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!

Ride quality & brakes 1 out of 5

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.

Engine 1 out of 5

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.

Reliability & build quality 1 out of 5

Fueling issue.

Value vs rivals 1 out of 5

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!

Equipment 2 out of 5

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.

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.
