European style wave rotors are a popular upgrade in the 1:1 motocross world as they dissipate heat and resist warping better than standard “round” rotors while also looking quite trick in the process. These rotors are a direct fit to the Losi Pro-Moto MX and SM and pair well with Pro-Line’s aluminum brake calipers ( sold separately). Sold in pairs, the steel rotors faithfully recreate the look and performance of 1:1 Galfer rotors, though they are not officially licensed copies.
