The two GSX-Rs are indistinguishable from the saddle. Riding position, rider interface, gauges and controls, the two-mode S-DMS—everything is as on the 600. Crack the throttle, however, and any similarity dissolves. The light bike (419 lbs., just 5 more than the 600) leaps forward more like a liter bike than its little brother, spinning its rear Bridgestone in spots where the 600 stuck like glue and appreciably shortening Barber’s straights. The 750 is also upgraded with Showa’s Big Piston Fork and Brembo Monobloc front brakes, but the bigger bike didn’t carve as smartly as the smaller one, feeling sluggish on corner entries and having difficulty holding a tight line on exits. Suzuki officials proudly pointed out the low, 31.9-inch seat height; after riding it we think the rear suspension was tuned for the showroom standover test, not sharp racetrack handling. Ride height is adjustable, however, and we guess that raising the rear end will make this bike handle just as well as the 600 does.
