520 Conversion F4i

520 Conversion F4i
All 520 Conversion kits come with a lightweight 7075-T6 alloy rear sprocket, drilled and lightened case hardened front sprocket, and an EK Quadra X-ring chain that is cut to length for the gearing option you choose.

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.
