Renthal Front Sprocket RMZ250 13-.. 13t UGP

Renthal’s Ultralight grooved off-road front chainwheels are chosen by more factory motocross and supercross teams than any other chainwheel on the market.

Designed to offer a long lasting front chainwheel in a lightweight design which offers maximum power transfer. They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel.

Mud grooves are CNC machined into each tooth on both sides to allow mud to flow away from the contact points between the chain and chainwheel. This reduces wear and increases the drivetrain lifespan
