Our new 270mm Solid Wave Rotor is made by Galfer exclusively for Ride Eng. The special grade stainless/iron alloy material is imported from Japan, manufactured in Spain, then imported to the US and is a favorite among most of the top level motocross teams. Beware of cheap aftermarket rotors like those imported from China, the material used may hinder braking performance. Our non-floating wave rotor is inexpensive, made to last, is very light weight (1lb 1oz) and offers more stopping power than the previous stock 250mm disc. (2016+ models its the same diameter as stock) (270MM Hanger bracket required 2015 and older models).
