The Suzuki GSX-S1000 has been a big success due its blend of ability, spec and value and this new, significantly updated version at only £300 more, is a worthy successor.

Its K5-derived powertrain and impressively competent chassis are improved and make for a great road bike and its electronics, quickshifter and new dash are welcome upgrades.

The new look is a step forward, too, but likely divisive. Best of all though is its value. This is a substantial, enjoyable, 1000cc naked that costs only slightly more than the more middleweight Yamaha MT-09SP and significantly undercuts all Japanese, let alone European, rivals. At that price, who cares about any quibbles?

If you're after a little more practicality, you might consider the 2022 Suzuki GSX-S1000GT sports tourer instead.

Although the GSX-S’s riding position has been tweaked, with bars that are 23mm wider and 20mm nearer the rider for a more upright riding position, although it’s still on the sporty side of neutral, its chassis is barely changed – and there’s nothing wrong with that.

The old GSX-S already came with impressively multi-adjustable suspension for such a ‘budget’ bike, and this unchanged bar some revised settings. The big Brembo radial brakes are carried over, too, and provide powerful, classy stopping power.

While the tyres are now new Dunlop Roadsmart 2s. Handling is sharp enough yet stable; ride is OK although without the cultured class of better equipped (and significantly more expensive) ‘super nakeds’ and overall its behaviour is significantly more cultured than its budget price suggests.

Smooth, grunty, responsive transverse four is still based on the ‘old’, long-stroke GSX-R1000 GSX-R1000 K5 motor but has had a hefty makeover.

New cams, valve springs, exhaust, revised injection, new airbox and more both help it become Euro5 compliant and gives a subtle boost to both peak power (2bhp extra) and midrange.

Aided by three switchable power modes, new standard quickshifter/autoblipper and improved slipper clutch it may be ‘only’ 150bhp compared to some £15K+ ‘super nakeds’ but is perfect in this form, exquisitely responsive, tractable and flexible, more than quick enough for the street and provides and endearing heart for a great real world, road bike.

It sounds better than ever, too. The only fly in the ointment is worsened economy – down from 50+ to a claimed 46mpg – although due to the larger tank range isn’t affected.

Quality and spec has taken a subtle but significant step up and the new GSX-S’s core mechanicals (engine, frame, suspension etc) are all refinements of the old bike rather than all-new, so there should be few reliability concerns.

That said, the changes to the engine are many, there’s the new ‘SIRS’ electronics suite, new ride-by-wire and more which, although already featuring on Suzuki’s latest V-Strom and Hayabusa, has yet to get extensive mileage under its belt. 

We don't have any owner reviews of the 2021-on bike, but the previous generation received loads of glowing reports in the main. Couple of isolated issues but nothing prevailing.

5 out of 5 (5/5)

In a world seemingly awash with ultra-exotic, £15K+, 170bhp super-nakeds, the £10K, 150bhp GSX-S has always stood out as value-packed, real-world alternative – and the same is true with this new version.

Although featuring all-new, bang-up-to-date styling, right down to its MotoGP-style ‘winglets’ and gaining performance, electronics, a quickshifter and more, this new GSX-S is only £300 more than the old version.

If you like the new, more aggressive looks – and so far they’re proving a bit ‘Marmite – you’ll be laughing all the way to the bank.

Some will argue that the GSX-S has been left behind by the likes of the Ducati Streetfighter V4 or Kawasaki Z H2 with their massive power, the Aprilia Tuono V4 or KTM 1290 Super Duke R with their massive torque and razor-sharp chassis or the BMW S1000R and Triumph Speed Triple 1200 RS with their cutting edge tech.

Equipment

4 out of 5 (4/5)

The old GSX-S was always, despite some quality cycle parts and decent performance,  conspicuously budget-orientated and affordability remains at the core of this new version.

That said, spec, equipment and more has taken a notable step up. The new ‘face’ is dominated by those twin stacked LED headlights, with LEDs elsewhere, too.

There’s an uprated, more sophisticated and stylish digital dash (although it’s still an LCD rather than TFT design), finishes and detailing are improved and the new GSX-S also gains Suzuki’s ‘SIRS’ (Suzuki Intelligent Ride System) electronics suite.

The system made its debut on the latest V-Strom and Hayabusa – although being an ‘affordable naked’ means the GSX-S gets the budget version with no IMU so no cornering traction/ABS etc.

Even so, comprising five-way traction, quickshifter, ‘Easi-start’, ‘low rpm assist’ and three riding modes it’s decent for the price and probably enough for most.

Model history & versions

Model history

  • 2015 - Suzuki GSX-S1000 launched as naked streetfighter version of the GSX-R1000 sportsbike. The engine was taken from a ten-year-old version of the GSX-R and is tuned for torque and useability rather than power.
  • 2021 - First major update since the bike's launch.

Other versions

In 2019, Suzuki reimagined a classic with a modern version of the Katana based on the previous GSX-S1000.

5 out of 5 Almost the perfect road bike

Cracking road bike - all of the road performance of the more expensive super-nakeds but with compliant suspension, superb comfort, minimal unnecessary electronics or oversensitive safety kit. Not classically handsome but better looking in the real world than in pictures. Rapid, comfy, practical, frugal, excellent value!

Ride quality & brakes 5 out of 5

Really comfy with great ride quality - our roads in NI and Scotland are rough as a badger's posterior - lumps and bumps absorbed well - and i'm a chunky person too - 18 stone (on a good day) - brakes are strong and have enough feel for road riding - i've heard they could do with being stronger for the track but as they are Brembo Units perhaps a more aggressive pad would sort this.

Engine 5 out of 5

My favourite Road engine was the K5 Gsxr 1000 - lovely road bike and great engine - now re-tuned for max torque and a very user-friendly delivery - you can ride this bike gently in 6th gear from 30 - 130 without complaint or go through the cogs for rapid progress - very nice noise - hugely flexible - perhaps a twin or triple would be more charismatic but really all you need.

Reliability & build quality 5 out of 5

Brand new so no issues so far - i've had suzukis in the past with no issues. The Gixxer engine should be bullet proof. Well-built and looks rugged

Value vs rivals 5 out of 5

Well priced with low monthly payments - servicing is reasonable - parts inexpensive - dealer service from GS Suzuki Ballymena excellent - they couldn't do enough for me - happy to set up suspension for me - free gifts and friendly staff.

Equipment 5 out of 5

All you need - comfy seat - 19 litre tank with potenital 200 mile range at around 50 mpg - closer to 47 if ridden enthusiatically (rude not to). Dash is fine once you get used to it - hard to read time/clock - don't even notice it now - quick-shifter is lovely up and down at any revs. Standard Dunlops are grippy and confidence inspiring - even in the wet and cold.

Buying experience: Superb - couldn't recommend Ballymena/ Hillsborough Suzuki highly enough - great servicing - kind and helpful staff - superb and reliable products.

Beautiful bike, very smooth engine Quick-shifter is a delight Handles really well and feels planted Comfortable and good mpg (50+)

Ride quality & brakes 5 out of 5

Very comfortable, brakes feel good Tank range is approximately 160-170 miles, perfect timing for a stretch

Engine 5 out of 5

Smooth and economical

Reliability & build quality 5 out of 5

It’s a Suzuki, so shouldn’t be any problems

Value vs rivals 5 out of 5

My local dealership (CJ Ball) has always offered good value servicing

Equipment 4 out of 5

The only fault I have with the bike is the display, very dim, especially on bright days. The digits are way too small Switchgear is good, very precise

Buying experience: Bought from what I consider to be one of the best dealerships in East Anglia, CJ Ball. Great part-ex and brilliant all round deal and service

5 out of 5 Perfect all rounder.

Superb bike all round

Ride quality & brakes 5 out of 5

Excellent all round bike, comfortable riding position, can easily do over an hour in the saddle without complaint. Brakes really strong and at its happiest on fast country roads. Only downside is it can require plenty of clutch control in slow traffic.

Engine 5 out of 5

The star of the show, all the power you’ll ever need in any gear. Makes a wicked noise and the performance is sensational. For the road you don’t need anymore power.

Reliability & build quality 5 out of 5

Only had the bike a few months but so far everything looking as good as the day I bought it. Impressed with the quality of all the switchgear and the bike has a very solid feel.

Value vs rivals 4 out of 5

For the performance you get, compared to the competition, the Suzuki is fantastic value for money.

Equipment 5 out of 5

Quick shifter works superbly well as has been a revelation. Dash is very clear and easy to ride (doesn’t need a TFT in my opinion.) Electronics are nice as a safety net.

Buying experience: Dealer, list price as it was a new bike.
