Check our lightweight brake rotor for the 2018 and newer Arctic Cat mountain sleds, Yamaha Mountain Max 800, Arctic Cat Riot X 2021. It's 3/4 of a pound lighter on 2021 models with the solid brake rotor, and 1/2 a pound lighter than the stock 18-20 drilled models. Less rotating weight and overall weight. This rotor also improves braking.
