This 270mm 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 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 great stopping power. This is a great replacement rotor for 2015+ KX250 and KX450 models.
