Unlike the 2011 GSX-R600 there are only minor changes to the 148bhp, 750cc inline-four-cylinder motor. It now has pentagonal-shaped ventilation holes in the block, instead of round, which they say reduces pumping losses inside the engine and creates more bottom end power.
The primary injector nozzles are changed from 41 to 35 degrees inside the throttle bodies. The gearbox remains the same. A revised, more efficient ECU has been moved from under the seat to the top of the airbox to save weight on the length of wiring loom.
Blip the throttle and you still get that angry, metallic GSX-R rasp from the airbox and exhaust. The revs spin up almost as quickly on the move, racing through the gears, as it does at a standstill. The GSX-R750’s performance is as much as you’ll ever need on the road or track.
