Our 520 Conversion kits come with a -1/+2 race gearing for an out of the box boost in acceleration using top of the line AFAM/Drive Systems or Stealth sprockets with chromoly steel front sprockets. 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. DID and RK chains come pre-cut to length but you can trim depending on your desired wheel base. EK chains come with 120 links. 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.
AFAM Sprockets are made with the latest tooth profiles for more efficient power delivery. Rears come in 7075-T6 hard anodized aluminum in gray.
Drive Systems' new DS-2 Superbike rear sprocket is made of strong 7075-T6 alloy and then black hard anodized for maximum strength and durability. Average weight per sprocket is less than a pound each. DS-2 rears are now used by Doug Chandler, Kurtis Roberts, the 2007 Factory Husqvarna Super Moto race team and Fast Company Yamaha.
Supersprox Stealth Rear Sprockets are the highest quality and most technological advanced sprockets in the world. Over four years of research, design and testing have yielded a fifth generation Stealth motorcycle sprocket that is nearly impossible to destroy. Stealth backs up that claim with an unheard of 100% Lifetime Guarantee against breakage. It screams hi-tech, strength and coolness.
