On the initial launch of the 2009 Kawasaki ZX-6R the engine improvements didn’t feel too significant, more midrange but not too much at the top end. However, the Japanese test track was at altitude, and now we’ve had the bike on the Dyno in the UK its easy to see the gains. Kawasaki is claiming a significant boost in the midrange which was always a weak point of the old bike with some serious power up at the top end.
