In 1990, the GSX-R750 was given a major model update. That year, Suzuki bestowed the GSX-R750 with a host of features borrowed from the race-spec double-R model (GSX-R750R), including its long-stroke engine layout, lighter pistons, new Mikuni model BST38SS “Slingshot” carbs, upgraded connecting rods and cylinder head, smaller valves, a revised stainless four-into-two-into-one exhaust culminating in a single muffler mounted on the right side, and new suspension that yielded increased adjustability.
The chassis also underwent revisions at the start of the decade, utilizing some elements form the 1989 GSX-R1100 with a 25.5-degree rake and a 55.7-inch wheelbase. A wider rear tire (which were now Michelin radials), up to 5.5-inches from the outgoing model’s 4.4-inch item and a steering damper was also added to the mix. The next year in 1991, the ‘Zook was given its first significant visual makeover, getting a new tail section, less rectangular-shaped side vents in the bodywork, and a new front fender was introduced to better accommodate the inverted front-end (though that last feature didn’t extend to US models).
The biggest change for ’91 was undeniably its new front fairing design. Gone were the original Suzuka-style double headlight arrangement, and in its place was a slanted nose fairing that hid headlights several inches behind a clear headlight cover, giving the bike a more aggressive and contemporary appearance while also bolstering aerodynamics. On top of also getting a new, larger seat, ’91 marked the final year of the oil-cooled SACS-engined version of the Gixxer.
Powering the 1991 Gixxer 750 was an air/oil-cooled, 749cc, 16V, DOHC, inline-four, married to a six-speed constant mesh transmission. All the changes resulted in an output of 116 hp at 11,000 rpm and 57.5 ft-lbs of torque at 10,000rpm, which translated to top speed exceeding 150 mph, and the ability to fire off standing quarter mile sprints in under 11 seconds — despite its approximately 550 lb wet weight.
