Suzuki GSX-R600 and GSX-R750 Review and Rating
Updated: Sep 2
The Suzuki GSX-R600 and GSX-R750 are faired inline-four supersport bikes aimed at track day riders, club racers and experienced road riders who want a light, mechanical sportbike with almost nothing between the throttle and the tire. Both are still sold new in the United States. Suzuki announced 2027 versions on 8 August 2026 and lists them at $12,499 plus $650 destination for the GSX-R600 and $13,549 plus $750 destination for the GSX-R750, with 40th Anniversary Z editions at $12,699 and $13,749. What you are buying, though, is a 2011 motorcycle. Cycle World states plainly that the GSX-R750 has not seen any updates since 2011, and Cycle News, testing a 2025 bike, wrote that it is exactly as it was back then.
Most riders should not buy one. There is no anti-lock braking and no traction control. Suzuki's own 2027 specification tables list the brakes with no mention of ABS, and Cycle News recorded the electronics as riding modes only, with no traction control and no ABS. If this is your first sportbike, if you ride in rain or cold, if you carry a passenger regularly, or if you want cruise control, a colour dash or a quickshifter, this is the wrong motorcycle. Buy one because you want the 2011 experience, not in spite of it.
What You Are Actually Buying
Both bikes use a twin-spar aluminium frame, a Showa Big Piston Fork, a remote-reservoir Showa shock adjustable for rebound, compression and ride height, and fully floating 310mm front discs squeezed by radial-mount Brembo Monobloc calipers. The GSX-R750 adds an electronically controlled steering damper that the GSX-R600 does not get. Otherwise the chassis is the same bike with a different engine in it.
The 2011 update was the last real one. Cycle News reports Suzuki claimed 19.8 pounds of weight saving at the time from a new chassis, lighter engine internals, a new exhaust, Brembo M4.32 calipers, the Showa fork, lighter wheels and lighter bodywork. Fifteen years later the same parts are fitted, which is why the bike still ships on Bridgestone Battlax BT016 tires, a tire Cycle News notes went out of production years ago and stays standard only because the machine was homologated on it in 2011.
GSX-R600, Suzuki US figures: 599cc, 67.0 x 42.5mm bore and stroke, 12.9:1 compression, 412 lb curb weight, 810mm (31.9 in) seat, 54.5 in wheelbase.
GSX-R750, Suzuki US figures: 750cc, 70.0 x 48.7mm, 12.5:1, 419 lb curb weight, same 810mm seat, 54.7 in wheelbase.
Both carry 4.5 US gallons, or 4.2 gallons on the California model.
Warranty is twelve months, unlimited mileage, on both.
The Engines and What They Actually Make
Suzuki does not publish horsepower for either bike in the US, so the useful numbers are measured ones. On the Cycle World Dynojet 250i, a 2023 GSX-R600 made 102.9 hp at 13,500 rpm and 44.0 lb-ft at 11,600 rpm. A 2022 GSX-R750 on the same dyno made 121.5 hp at 12,560 rpm and 53.0 lb-ft at 10,840 rpm. Those are rear wheel figures. MCN's UK pages for the 2011 to 2018 models quote crank claims of 126 bhp and 148 bhp respectively, so expect roughly an 18 percent gap between the marketing number and the ground.
The character difference is larger than 19 hp suggests. Cycle World described the GSX-R600 as having a linear curve and lackluster bottom-end torque that forces the rider to keep the revs up. The 750 makes nine more lb-ft and makes it 800 rpm lower, which means fewer downshifts on the road and a bike that pulls out of a slow corner without drama. MCN reached the same conclusion years ago: unless you were racing a 600 class, the 750 was the sensible buy.
Cycle World's automotive scales read 419 lb for the GSX-R600 and 428 lb for the GSX-R750, seven to nine pounds above Suzuki's published curb figures. Treat the factory numbers as the optimistic end.
No ABS, No Traction Control, and What That Means
This is the single most important thing to understand before buying. Suzuki's rider aid package on both bikes is the Suzuki Drive Mode Selector, which offers push-button selection of two engine maps, plus an instrument cluster with a lap timer and a programmable shift light. That is the whole list. No lean-sensitive anything, no wheelie control, no cornering ABS, no ABS at all.
On a dry track that is a feature. Cycle News argued that 120 to 125 rear wheel horsepower with no electronic safety net is more than most riders need and forces you to stay present. On a cold, damp road it is a real limitation, and these bikes ask for skill that a modern 700cc twin does not. One MCN owner puts it plainly: the bike has none of the ABS, traction control or other electronics of modern machinery.
The brakes deserve a separate warning. Cycle News found the Brembo M4.32 calipers and their matching master cylinder wooden in feel and said an upgrade would be the first money they would spend on the bike. There is enough outright power, but the feel is fifteen years old.
Ergonomics and Running Costs
The 810mm (31.9 inch) seat is low for a supersport machine, and it is the reason these bikes suit shorter riders better than the class average. An MCN tester at 5 feet 7 inches reported getting both feet flat on the floor and found the riding position roomier than the hunched look implies. Three-way adjustable footpegs and an adjustable shift lever are standard on both.
Fuel economy is where the four-cylinder layout costs you. MCN records averages of 42 mpg for the GSX-R600 and 39 mpg for the GSX-R750 in imperial gallons, which works out to roughly 35 and 32.5 US mpg. Against a 4.5 gallon tank that is a short leg between fill-ups if you are riding hard. MCN also lists an annual service cost of about 260 pounds for the 750 and puts the two bikes in UK insurance groups 15 and 16 out of 17, a fair warning that US supersport insurance is not cheap either.
Recalls and Known Faults
Two NHTSA campaigns matter on used bikes, and both are worth checking by VIN.
Campaign 13V449, Suzuki's 2A31 through 2A36, covered 2004 to 2013 GSX-R600 and GSX-R750 models plus 2005 to 2013 GSX-R1000. Corrosion of the front brake master cylinder piston, combined with older brake fluid, could generate gas and reduce pressure to the front brake. Dealers replaced the master cylinder free from 18 November 2013.
Campaign 14V629, Suzuki's 2A40 through 2A43, covered 2011 to 2014 GSX-R750 and 2009 to 2014 GSX-R1000, and Motorcycle.com reported it at 23,073 machines. If a gear was missed on an upshift, the strain on the drive chain at the next shift could move the rear axle and damage the left-side chain adjuster, potentially throwing the chain. Dealers fitted an improved adjuster free and the recall began on 17 October 2014.
Beyond those, no chronic mechanical fault is widely documented. MCN says there are no prevailing problems on the 750 and nothing beyond thin paint on the 600. What it warns about is history: many used examples have been tracked, thrashed or dropped, so check for non-matching panels, mismatched fasteners and resprays before you check anything mechanical.
How They Compare
The direct rival is the Kawasaki Ninja ZX-6R. In Cycle World's own database the ZX-6R measured 108.4 hp against the GSX-R600's 102.9, at 432 lb against 419 lb, so the power-to-weight is close enough that the deciding factors are brakes, electronics and price. At the time of its 2025 test Cycle News listed the ZX-6R at $11,300 and Yamaha's then-new R9 at $12,499, and argued the Suzuki was hard to justify at its own price given a 14 year old design.
That criticism has only sharpened. The GSX-R600 now costs $12,499 plus destination for a machine with no ABS, while newer middleweights in the same money bring rider aids, a TFT dash and a quickshifter as standard. The counter-argument is the 750. There is still nothing else on the US market that puts 121 rear wheel horsepower in a 600-sized chassis at 419 lb, and for a club racer or a trackday regular that combination is the entire point.
Common Questions
Is the Suzuki GSX-R600 still made in 2026?
Yes, Suzuki still sells both the GSX-R600 and the GSX-R750 new in the United States, and announced 2027 versions on 8 August 2026. They are not sold in the UK, where Suzuki's current range page lists only the GSX-R1000R and GSX-R125, and MCN treats both models as 2011 to 2018 machines.
Does the Suzuki GSX-R600 or GSX-R750 have ABS?
No. Neither bike has anti-lock brakes or traction control in any trim or model year currently sold. Suzuki's 2027 specification tables list the brakes without ABS, and Cycle News confirmed the same on a 2025 GSX-R750. The only electronic rider aid is a two-position engine map switch.
Should I buy the GSX-R600 or the GSX-R750?
Buy the 750 unless a racing class requires a 600. It costs $1,050 more at list, weighs seven pounds more by Suzuki's numbers, and makes about 19 more measured horsepower and nine more lb-ft on the Cycle World dyno, arriving lower in the rev range. The 600 makes sense as a supersport race platform and as the cheaper way into the same chassis.
Should You Buy One
Buy a GSX-R750 if you want the last simple Japanese supersport, you ride mostly in dry conditions or on track, and you will budget for a brake master cylinder and modern tires straight away. The chassis is genuinely good, the engine is a rare middle ground between a screaming 600 and an intimidating litre bike, and the reliability record is clean. Buy a GSX-R600 only if you race a class that mandates it, or if you find a well documented used one cheaply.
Skip both if you want a road bike. At this money a modern middleweight gives you ABS, traction control and a quickshifter, and MCN's comparison logic from a decade ago still holds. A used GSX-R750 from this same 2011 generation, with a service history and no track damage, is the smartest version of this purchase.
On gear, treat these as what they are. Supersport riding means armour, so look for CE-rated protectors at shoulders, elbows, back, hips and knees, and a one-piece or zip-together suit with a certification label. Unarmoured leather is weather protection, not crash protection, no matter how good it looks.
Rating: 3.5 out of 5. The GSX-R750 in particular is a wonderful motorcycle and would rate higher on the ride alone. It loses points for a 2011 specification sold at a 2027 price, obsolete standard tires and the complete absence of ABS on a machine making well over 100 horsepower.
