controlled acceleration.
.
The engine's power character is specifically tuned to provide ample low-to-mid rpm range torque.
.
Extra-fine-atomization injectors, optimized camshaft profiles, transistorized ignition system, iridium
spark plugs and other technologies result in state-of-the-art efficiency.
.
Such high-efficiency designs help maximize smooth throttle response, allow delivery of immediate,
controlled acceleration, and provide ample low-to-mid range torque.
.
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.
