hi all recently bought a chain and sprocket kit an got supplied a 5 holed rear sprocket which i have replaced with a 6 holed sprocket
will it fit onto a zxr400 of a later model ???


cheers

The standard gearing for the road is 15 front 45 rear. This is no use for the track as the initial acceleration will be far too sluggish and I would recommend 14 / 46 as a starting point. As the days on track and differing circuits you'll have to change it again to suit.
