All 520 Conversion kits come with a lightweight 7075-T6 alloy rear sprocket, drilled and lightened case hardened front sprocket, and x-ring racing chain cut to length.
Bolt-on horsepower gains of 5-7% are typical from the parts alone. But combine this with one of our gearing ratios and you can transform your bike into something you didn't think possible.
This is a quick and easy way to gain performance and replace your stock pieces for less money.
Stage 1 is -1/+2 setup or a +5 setup (equal the same)
