The Suzuki GSX-R1000 K9 get a shorter-stroke engine for the first time, which Suzuki claims makes the same power and torque as the old model. Strangely our dyno results show it’s actually 7bhp down on the old bike, making 161bhp at the back wheel. The idea of the shorter stroke engine is to allow race teams to tune them and raise revs safely, compared to the old long-stroke motor. The power delivery has been softened off in the mid-range compared to the old bike, which gives you the confidence to open the throttle sooner and harder. There’s still lots of grunt to play with, despite the shorter stroke motor. The engine is physically 59mm shorter than before to allow for a longer swingarm, which aids rear tyre grip.
