2015 Suzuki GSX-S750

As a motorcycle rider in Southern California, it’s hard to complain about anything. The temperate weather and lack of rain allows me to ride to work all but a handful of days a year, and lane splitting is accepted. We have mountain and canyon roads a stone’s throw away, as well as a scenic coastline to trace. Still, it was hard not to wince when Suzuki announced its 2015 Suzuki GSX-S750 and there was a little asterisk next to it saying, “This model is not available in California.” Say it ain’t so!

With a powerplant based on the decade-old Suzuki GSX-R750 K5, but tweaked for more street friendly sport riding, Suzuki has really nailed it with the S750. It all starts with that wonderfully smooth DOHC inline-4 that is supple and responsive, and a complete pleasure to ride. With an emphasis on low and mid-range torque, where most of us spend our time, the GSX-S750 has an even-tempered personality. But, a twist of the throttle reveals plenty of sporty acceleration just waiting to be unleashed.

Ergonomically, the S750 is a compact bike that feels lighter than its 470-pound claimed curb weight, as well as shorter than its 32-inch seat height. I was particularly surprised by the latter stat, as I have no problem getting two feet flat on the ground at a stop with just a 30.5-inch inseam. Credit goes to the narrow-waisted design of the bike.

2015 Suzuki GSX-S750 Test | Commuter & Sport ReviewSuzuki outfitted the GSX-S750 with handlebars instead of the Gixxer clip-ons, which gives the bike a less aggressive riding position. Coupled with a mid-sized engine configuration that takes less effort to mind, the S750 is physically easy to handle, making me feel like the master of the machine. With plenty of aggressive styling cues and a satisfying sound from the exhaust, it’s the perfect recipe for pushing one’s limits.

The Suzuki GSX-S750 has a late engaging clutch, which makes pulling away quickly from a stop something you have to pay attention to. You’ll get used to it soon enough, however; I would have forgotten to mention it after all the miles I’ve put on the bike if I hadn’t made a note about it.

Shifting through the six-speed transmission is smooth and sure and, if you’re riding aggressively in pursuit of your riding buddy in the canyons, you’ll do more of it to access the power. Around town, however, you don’t need to row the gearbox. Roll on and off the throttle and enjoy the smoothly delivered torque.

The GSX-S750’s slim profile makes it easy to maneuver in tight quarters. Coupled with the engine’s seamless personality, the Suzuki is a wonderful commuting partner. It will happily accommodate an exhilarating ride home when traffic disappears; acceleration is so effortless that it is plain hard not to find yourself going too fast. It takes restraint to not just twist the throttle and chase down the far-flung taillights ahead, regardless of what the speedo says, just because you can.

The S750’s smooth engine is rather intoxicating; when you’re on-throttle, you feel the busy, pleasing hum of the four cylinders under you. There’s not enough windblast coming off the naked bike to encourage you to keep the speed down, and the bike’s 57-inch wheelbase contributes to a solid feel. Happily, the mirrors are vibration-free even at high speeds, so you can keep a keen eye on other vehicles, especially those in black-and-white and overly concerned about your speed.

With a fast accelerating bike, you need correspondingly capable brakes. The dual 310mm discs with calipers that are disappointingly not radially mounted, while adequate, are not exactly confidence inspiring. There is a lot of play at the brake lever, so the initial squeeze doesn’t slow the GSX-S750 much. An authoritative grip on the linear brakes will haul you down from top speed, though not as quickly as I would like. It’s surprising that Suzuki did not outfit the bike with more reassuring brakes that would allow you to ride at the upper end with more confidence. The single 240mm rear rotor is well suited to its job, and has good feel.

Taking the 2015 Suzuki GSX-S750 on a favorite 100-mile sport bike loop gave me the full measure of the bike’s sport capabilities. Winding through the Santa Monica Mountains, and then dropping down to Pacific Coast Highway briefly before diving back into the mountains, I encountered a variety of conditions. No matter where I went, the excellent Bridgestone Battlax BT016 rubber did everything I asked without surprises.

The S750’s suspension had its work cut out for it. Stiff enough for the canyon carving and stable through the sweepers, it isn’t so tightly tuned as to get unsettled on the crunchy bumpy road. Still, that segment was no fun on the GSX-S750 and would be better on an adventure bike.

Nicely balanced, and with a moderate 25-degree steering angle, the bike transitions well through turns without being overly responsive or nervous; there are certainly more flickable bikes, but they require a lot more attention. The S750’s inline-4 doesn’t have much engine braking, but you can still carve through the hills without touching the left foot lever as the plentiful mid-range torque allows you to accelerate quickly out of turns and build speed on the short stretches of straights, before squeezing hard on the brakes for the next turn.

On extended rides, such as the twice as long Sunday blitz out to New Cuyama for a late lunch, I noticed there wasn’t much room to move around on the saddle, nor much repositioning of my Sidi Livia Rain boots on the pegs. Two hours are about the max comfort for a spirited ride on the GSX-S750 before I start fidgeting, so I’m not going to empty the 4.6 gallon-tank before I need a break.

Unlike technologically superior competitors, the S750 doesn’t have any power modes to choose between, nor suspension settings or traction control profiles. Still, this simple, straightforward bike delivers that super-smooth inline-4 feel with style and comfort, and is immensely capable of canyon runs, commuting duties, and the around-town urban blast. Plus, by passing on the latest electronics, Suzuki can keep the price below $8000. The 2015 Suzuki GSX-S750 is a terrific mid-size bike that will please a wide swath of sportbike riders, though you’ll need to find a used one with 7500 miles on it if you live in California.
