The Suzuki GSX-R1100 1990 brings to the open class of production motorcycles an all-around superiority won in successful factory racing actions and proven in a wide range of production endurance racing events.
Powerful, circuit-bred performance features like engine improvements straight out of the factory teamís race shop, rigid inverted front forks and Suzuki’s unique progressive link rear suspension – all cradled within an aluminum-alloy frame and swingarm whose efficiency has been proved with modified racing engines.
The Suzuki GSX-R1100 1990 is another Suzuki success in efficient application of racing technology to street bikes. Itís direct-access racing technology in action.
The latest Suzuki GSX-R 1100 1990, 1127cc, powerhouse features cylinder head designs straight from the factory racers:
- Valve seats are smoothly blended with reshaped intake ports for better cylinder charging and higher torque.
- Use of lightweight, single rocker arms to open each valve, and use of small shims to adjust valve lash, reduces inertial mass and mechanical losses.
- Double-row ball bearing is used on the transmission output shaft.
- Crankcase system sprays a constant stream of oil on the 3rd, 4th and 5th gearsets for better gear lubrication and cooling.
- Suzuki Advanced Cooling System (SACS), combined with air cooling, efficiently carries engine heat away to the high-capacity curved Radial Flow cooler.
- Larger 40mm Slingshot carburetors maintain quick engine response.
- A remote choke control lever is conveniently positioned on the left handlebar.
- Cool-air induction system routes cool, dense air from the fairing intake to the airbox.
- Aluminum-alloy double-cradle frame, together with swingarm reinforced with gussets, features rigidity well proven with modified racing engines.
- Inverted front forks have higher rigidity and provide better fork response. Suzukiís unique progressive link rear suspension system is combined with a remote-reservoir rear shock.
- Wide aluminum-alloy wheels with hollow spokes carry high-performance 17-inch front and rear radial tires.
- 310mm front brake discs with surface slotting and floating carrier mounts are mounted, together with 4-piston calipers with staggered piston sizes.
- Factory racer-derived, narrower fairing with flush-mounted headlights, along with sidecovers and tailsection, are wind-tunnel refined and provide better aerodynamics.
