The 750 Naked bike class has just gained a formidable entry. Suzuki Motor of America as taken the wraps off the 2015 Suzuki GSX-S750 and GSX-S750Z, which our European readers will recognize as the GSR750 that’s been available on the Continent since 2011 but will now arrive in the U.S. for the first time. These functionally identical motorcycles will certainly enliven what has been an energetic class in the last year.

Using the engine from Suzuki’s best selling model – the GSX-R750 – as a starting point, the GSX-S750’s 749cc mill has been massaged to deliver performance in the rpm range most commonly encountered on the street. With the charges and spent gasses flowing through specially designed intake/exhaust tracts, the valves are directly operated by cam profiles designed to produce bottom-end torque coupled with mid-range power for optimal streeting acceleration.


Suzuki’s Dual Throttle Valve (SDTV) controls the delivery of the air/fuel mixture for smooth throttle response, while new iridium spark plugs initiate the combustion with a hotter, more powerful spark for a more efficient burn. Iridium plugs also reduce maintenance thanks to increased plug longevity. The triangular muffler shares a family resemblance with Suzuki’s GSX-R line.

The chassis of the GSX-S blends a twin-spar frame with a tubular rear section and then attaches it to an inverted fork and a link-type shock controlling a steel swingarm. Dual 310mm discs and 2-piston calipers handle front braking duties while a 240mm rear disc is clamped by a single-piston binder.


The 32.1 in. seat height mates with an aggressively upright riding position. A matte silver painted super bike-style handlebar reaches back to the pilot to ease the navigation of urban obstacles or sinewy backroads. The tightly integrated package announces the GSX-S750’s miscreant tendencies through thoroughly modern, angular bodywork that is best illustrated by the design of the 4.6-gal. tank and tail section with its LED taillight. Suzuki claims a 463 lb. wet weight and a 57.1 in. wheelbase. Rake and trail figures are as yet unavailable.

The instrument cluster features a large analog tachometer with a LCD digital speedometer plus readouts for gear-position, coolant temperature, fuel gauge, dual tripmeters, fuel consumption and a clock. The backlight has adjustable brightness.


Colors and styling are what differentiate the S750 and the S750Z. Where the GSX-S750 is only available in Metallic Matte Black, the GSX-S750Z stands out in Metallic Triton Blue / Pearl Glacier White. Additionally, outer fork tubes of the Z are anodized in a yellowy-gold color instead of a lighter gold hue, plus red-anodized fork adjuster bolts, a red shock spring and blue chain.

Pricing is as aggressive as the bikes’ styling, with the GSX-S750 retailing for $7,999, and the GSX-S750Z only slightly higher at $8,149. No on-sale date has been set.

    Let the middleweight naked battle commence!!! FZ-07 vs. FZ-09 vs. GSX-S750!!! Throw in a few European bikes for some spice, and see what happens. I can’t wait!

  • little britches

    Hmm, its priced right, should be decent competition for the FZ09. Should make a little more HP but a little less TQ than the FZ. It looks like it will weigh close to 50lbs more though. At that price did Suzuki put non adj cheap suspension on it too? The FZ09 is a great bike with rotten suspension, that thing pogo’s terribly if the rider weighs anymore than 150lbs.

  • Y.A.

    Damn it Suzuki… I asked for a naked 750, and now you brought one. Gotta put my money where my mouth is I guess!

  • Zandit75

    I would take the MV Agusta Brutale over this any day!

    • DickRuble

      I’d take a Cagiva V-Raptor over the Brutale any day..

      • Zandit75

        Go for it! I guess we all can’t live in the past!

        • DickRuble

          We can’t all spend our time dreaming of bikes we can’t afford either.

          • Zandit75

            I think you will find the gap is less than that. At least it is here in Australia!

  • DickRuble

    Why are decent ergonomics and wind protection totally incompatible in the vision of motorcycle manufacturers? Why can’t we have this bike with a full fairing?

    • Mark D

      Its called a GSX-R 750 with aftermarket bars.

      • DickRuble

        Needs lower , forward pegs , and slightly reconfigured saddle. Taller windshield completes the package…

    • Y.A.

      They were for a while…. Bandits, Fazers, CBFs…. and there are a few out now, like the VFRs, the Ninja 1000 and the GSX-S1000F. I agree though that it would be nice to have wind protection on these middleweights. I have been riding a naked ER-6 for about 3 years now and I am about ready to have a faired bike again. But I don’t need the power or want the weight/insurance/running costs of one of the thousands, and the VFR800 is comically overpriced.

      You gotta admit though, naked bikes LOOK a lot better than faired ones, especially with upright bars

      • DickRuble

        Looks and sound are dead last on my list of attributes of a desirable motorcycle.

        • Y.A.

          You are in a minority.


    Bring this back. Just update the suspension, brakes and muffler, and add abs. Style it exactly like the original. Use today’s 800cc engine.

    • Sentinel

      No! Don’t put a “VTEC” based engine in any motorcycle ever!

      • Glenn Lutic

        I agree! That bike has a great riding position, and wind protection! Kind of makes a guy wonder why they cannot seem to get it right. Right now Honda is stuck in their “lets get non-riders to become riders” mentality. ie.-NM4 CTX,NT, CB,CBR125, etc. etc.

  • ozziebloke69

    Don’t get too excited about this, dear US readers. This bike has been on sale in Australia and Europe for a few years now and it is not very good. Loses every group test against the MT-09 and Street Triple. Same will happen your side of the pond unless Suzuki brings in serious suspension upgrades.

    • Sentinel

      I’m going to do some studying up on this, but suspensions are always upgradable if need be. How has it fared in other aspects of the comparisons such as engine performance, brakes, handling and the like?

      • ozziebloke69

        I will look for some group tests I may have saved down somewhere and post back for you, Sentinel. Yeah, do your research before you buy.

        • Sentinel

          So far I’m coming up with standard garbage suspension and brakes Suzuki is still equipping their more budget minded bikes with. That right there rules the bike out for me already. This company is just full of fail.

          • ozziebloke69

            Found some older group tests for you. They all say basically the same thing – it’s competent but bland. User-friendly and easy to ride, but indistinct. It’s transport, but does nothing to excite. Fine if you want that kind of thing and maybe attractive to novice or timid riders.

            Bike magazine from the UK said “it’s hard to find much to say about it beyond a shrug and ‘Yeah, s’okay.’ Faults? None. Positives? That it hasn’t got any faults?”

            Hard to justify the money when it’s up against the truly brilliant Street Triple and the new Yamahas (FZ-09 and FZ-07, aka MT-09 and MT-07 in markets outside the US).

            Power-wise it has been tested at 100bhp, a few more than the Triumph Street Triple and quite a few less than the FZ-09. One test said the ex GSX-R750 motor had been “remapped and strangled from 123bhp down to 100, with unnoticeable reciprocal boost in the midrange or bottom end”.

            So if you were expecting a naked GSX-R750, prepare to be disappointed. And if you really want a naked GSX-R750, then buy a 3 or 5 year old GSX-R750, rip the fairings off and fit flat bars.

          • Sentinel

            The brakes are very inadequate as well.

          • Nyttnick

            Well. Got this bike and its lot of fun. Frontwheel leavs the ground round 8000 rpm in 1 gear, and is easy to control. Breaks are ok. YouTube video shows that a good driver can do quick laps compered with the gsxr 750. British tests allways give the english triumph a lead, regard what they test against. Have nevet seen the yma beat this bike in any test.

          • y001Thomas Grim

            I’m picking mine up at the end of the month. Some people just don’t get it. I mean, who wants to ride an 8000 USD bike with 100 horses and only a decent suspension? God help us if we feel the need to use a little back brake as opposed to 1 finger.
            This engine is tried and proven and i love the looks of this bike.Don’t want to get in to the fact that the Yamaha FZ-09 has had several known engine issues that continue to be sorted out by Yamaha.

          • y001Thomas Grim

            The bike is 8000 MSRP and nothing is garbage about it. I can not wait to pick up my smooth 100 HP, 140 top speed S750 with last generation brakes and suspension.

          • Sentinel

            To the point, if you are an aggressive rider, you like to ride hard in the canyons and such, you will find the brakes and suspension very limiting and even a safety issue. If you only commute on it and ride the highways/freeways, you will have less comfort and braking control. The good news it that both the brakes and the suspension can be upgraded, but it will cost you some time and money. I’d like to see Suzuki give this bike some four-piston Tokico brakes, and some upgraded Showa suspension, and charge a bit more for it.

          • Evans Brasfield

            Calling the brakes a potential safety issue is overstating things a bit. While they aren’t the strongest, their power would likely be improved with a more aggressive compound.


          • Sentinel

            I see your point, but guarantee you those brakes are a safety risk at speed in the canyons, those are the same calipers on my Gladius. I flushed the fluid and installed better pads, and that helped, but now I’m upgrading to stainless lines and a Brembo Mater-cylinder. That should make them a world better. As for the suspension, I’ll be going for emulators and new springs up front, and a new shock out back. I imagine with those same upgrades the GSX-S750 would be a great bike all around.

          • y001Thomas Grim

            Competent reviewers have pegged this suspension as being better than the FZ-09’s and overall decent at this price point. The brakes are competent but obviously require more pull than higher end Brembo or Nissan for that matter. A little back brake should be applied during normal every day riding anyway. Sometimes decent is good enough. Yes upgrading these components will improve this bike. I feel that you are nitpicking and this bike is one of the best bikes and values on the road.

          • Sentinel

            I like the bike, I’m just pointing out the fact that for those who are aggressive riders and those who ride the canyons, the brakes and suspension will need to be upgraded or you’ll be hitting their limits and moving into the danger zone far too often. These bikes have great potential that is held back by those components. When I upgraded my tires from the stock ones Suzuki had on the bike to a set of Michelin Road Pilot 4s the difference all the way around was huge. For myself, if I were buying the GSX-S750, I’d be upgrading the brakes, suspension, and tires and then I’m sure I’d be perfectly happy with it.

          • Sentinel

            Furthermore, I’d take that GSX-750 over the FZ-09 in a heartbeat. I rented an FZ-09, and by the end of the week the CCT had failed, and overall the bike was a mess to ride because of the suspension and hellishly twitchy/jerky throttle. I’m actually not even ruling out the GSX-S750 for myself at some point, because I like to mod my bikes to fit me anyways, and I know I could make that bike do what I want it to and love it.

          • y001Thomas Grim

            Ok I get it, thanks sir.

    • y001Thomas Grim

      this suspension has been consistantly getting better reviews than the fz-09. Most components on this bike are not new or cutting edge. this is a badd ass looking, good all around motorcycle. It is very smooth and handles well. We aren’t all interested in all new parts with a torque monster engine. I am very excited about this bike even with its detuned legendary k Gixxer engine.

  • sgray44444

    Oh no! Tuned for torqued strikes again! Why do all these manufacturers over-think this? Just take a GSXR750 and make it more comfortable. Done.
    I agree that some wind protection would be nice. I know it’s not in fashion right now, but after riding a Speed Triple for some time, I wouldn’t buy another naked bike. Maybe I’m just getting old.

  • Craig Hoffman

    Pity Yamaha does not update it’s FZ1. I own one. The bike has it’s fixable faults, but it also has the perfect bikini fairing, right out of the box. This bike just screams cheap with the 2 piston calipers and box swingarm. I guess it is cheap so there you go.

    It would be interesting to lay a dyno chart for this bike over a current GSXR 750. My guess is there would be little if any advantage below 7,000 rpm and the GSXR would destroy it above that. “Tuned for torque” is generally a lie. “Detuned” is the truth, but that would not be too appealing for the marketing materials eh?

    I like this bike’s handlebar, tidy instrument package and the general look, especially the dirt bike inspired radiator shrouds. It is a pity really. Do it right. Put real suspension on it and a real motor. Sell it for slightly less than the sport bike due to the savings on plastic body panels. People want a non dumbed down version of this bike from Japan. They really do!

  • y001Thomas Grim

    wow, i just realized that this discussion is years old!
