Suzuki GSX-R 750
The 1991-year's GSX-R750M weighed 15 kg more than the previous model! Some Suzuki sales brochures didn't even bother to quote a weight figure. The weight factor alone sends this bike to the back of the GSX-R pack. New aerodynamic fairing with slanted nose to reduce frontal drag, with distinctive headlight cover and running lights. The seat was enlarged and twin tail lamp design graced the backend. The oil-cooled SACS engine received internal refinement of adopting one rocker arm per valve from the previous of one per two valves, stronger valve springs and an exhaust cam with 7 degrees less duration to give 116 hp. GSX-R 750l History 1988-1991 In addition to SACS and Hyper Sports, this Suzuki GSX-R also had ‘Slingshot’ emblazoned on its flanks. This came from the bike’s redesigned Mikuni carburetors, which had straighter intakes for better combustion efficiency. This GSX-R, with its then radical, all-new styling, looked menacing. Mess with it and it would kill you.
It was on the exit to a second gear corner on my way home from the office. It was dark, and the reasonably adequate twin idlights were picking out the black, asy surface as they had done several times already. But there was something strange about way the bike was responding to an enusiastic fistful of throttle. The back of bike felt soft and the bars were just The sudden dawning of realisation snapped the throttle shut and with barely a quiver the bike snicked back into line. All a complete accident, of course, but it illustrates exactly the GSX-R's flawless engine and chassis response. Even with minimal protection of jeans and a leather jacket I hadn't felt frightened or relieved; just impressed. The 750L can't help being impressive. It sets new standards for power in its class, has the finest suspension of any production roadbike, carburates impeccably and will smoke a quarter in 10.89 seconds, making it the first 750 to get inside the elevens. Within the constraints of its design brief and price it's pretty close to ideal. Add a little more torque, higher gearing and a V4 exhaust note and it could be an RC30. It wheelies over bumps like one. Yum yum yum. The philosophy is basic GSX-R (light, powerful motor, racing steering geometry and the widest tyres current technology will permit) with a refinement: soft, soft springing, front and rear, backed up by very high quality damping. The advantages are ride comfort and the highest possible degree of wheel control, tuneable to any conditions. The disadvantages are that it's all very confusing; it interacts subtly. Even a passer-by fiddling with the SUZUKI In fact, unlike the 1100, the 750's stock settings are very good but because you, the rider, have all that adjustment, you end up desperately wondering if you've got it right instead of just riding the thing. I felt in constant fear of a man in an Ohlins van pulling up alongside me at the lights: "Hah! What are ya? Rear rebound on position three? Yer wanker." Etc, etc. Fortunately this never happened. Riding the GSX-R on the open road is a world of minimal effort, almost a state of grace. For a start, it makes the 1100 feel like a tank. You can place the 750 exactly where you want with time to spare, flick it into bends with opposite body lean like Kevin Schwantz, climb off it for a right-hander while the bike's still exiting the previous left. One finger pressure on the bars — I tried this — is enough to guide the bike accurately through a 90mph corner. This is the Suzuki at its best. Nothing can match the isolation of the unsprung mass from road shocks. The motor revs so incredibly smoothly, the motion of the suspension is so refined, the gliding sensation so complete... it's as if every bearing in the engine, wheels, chain and Full Floater linkage is working at the peak of perfection, greased by the finest grease in the world. The whole bike is a study in chassis excellence. The motor suits this character perfectly. Apart from the sheer brute force of 95bhp (125mph in under 11 seconds and all that) it's the smoothness and evenness which impresses. It needs choke first thing in the morning but you can knock it off straight away and get a clean-running, driveable motor which ticks over evenly. When it's warm it'll take 25mph in top, the well-damped response from the 38mm CV Slingshots permitting snatch-free acceleration at any revs in any gear. Transmission slop is absent. The killer action is between 10,000 and 12,000. Meanwhile, the pillion: detailed comment was unavailable due to an abundance of four-lettered expletives. The footrests are too high, the seat is slippery, there's no grab rail, the passenger's head sticks up into the airstream and all his/her weight is taken through the coccyx. Apart from that it was luxury. For the rider, the extra weight and responsibility completely kill the bike's fast-turning, hard-braking ability. You have to ride the bike so gingerly that the wrist-heavy riding position starts hurting within ten miles, whereas solo is good for 200. If you're planning lots of two-up riding, slow riding, or both, buy something else. In day to day use the Suzuki coped reasonably. A tiny magnetic tankbag will just about fit but carrying luggage on the back isn't really possible if you value your paintwork, and the stooped riding position rules out a rucksack if you value the blood circulation in your arms. After two weeks I came to the conclusion that the GSX-R is too delicate a creation for real life. I could already feel road grit in the damping adjusters. If it were mine, I'd have simply refused to ride it in the rain. All that bare alloy — it'd be a crime to use the bike at all in winter. An astonishing bike to ride, but make sure you understand its limitations before you buy one. Source Performance Bike 1990 |
