Our Yamaha 520 Conversion motorcycle chain & sprocket kits come with a pre-set -1/+2 race gearing for an out of the box boost in acceleration using top of the line Driven rear sprockets paired with steel front sprockets and a 520 chain to put it all together. Expect to see an 8-10% increase in torque. This setup will lower your top end a little but many feel it is an acceptable loss for the performance gains. This kit will also save considerable weight off your drive train - increasing responsiveness and performance. 

Bike selections are pre-set with -1/+2 gearing, however, if you want different gearing, simply enter it into the 'custom gearing' field.

Chains come pre-cut for your application. We recommend the RK Chain Riveting/Breaking Tool for installation and the Speedohealer to correct the speedometer once the kit is installed. Traditionally, aluminum sprockets will wear faster than the stock steel sprockets but you will save considerable weight with the switch. Take care of your chain with chain clean & lube/wax to see longer life from your kit.
