Front sprocket specially designed for off-road, signed Moose Offroad Hard - Parts. Machined from high-strength chromoly steel, it withstands the demands of motocross while limiting deformation under impact. Its nickel-plated finish, applied after heat treatment, provides a layer of protection against corrosion and improves sliding in contact with the chain.
The internal splines are machined to ensure maximum contact with the secondary shaft and an even distribution of transmission forces — a crucial point when you’re sending it hard on rough trails. Before installation, check the clearance around the sprocket if you opt for a different number of teeth than the original.
Examples of common compatible bikes: SUZUKI RM 85 (2018–2019) and YAMAHA YZ 80 (4LC). For a smooth installation, confirm the pitch 428 and the matching of the splines with your secondary shaft.
