    The engine’s efficient power output translates into an outstandingly user-friendly running performance in a variety of riding situations. The above engine designs also make the GSR750 10% more fuel-efficient (WMTC mode, Suzuki in- house research) than the GSR600. Specifications...
  • Page 24: Modifications For Low-to-mid Rpm Range Torque

    The cam profiles are designed to optimize the valve timing to tune the GSX-R750 engine – which is designed keeping in mind racetrack use – to obtain the GSR750 power character that’s more suited to the streets and winding roads.
  • Page 25: Transmission

    Benefit The transmission realizes smooth operation and acceleration, contributing to reduction of engine power losses. Power band utilization can be maximized by optimizing the gear ratio for GSR750. (5) Suzuki Exhaust Tuning (SET) Features SET is an exhaust device that opens/closes a butterfly valve in accordance with the engine rpm.
