Moose Offroad Hard-Parts Rear Sprocket made of 7075 T651 aluminium, specially designed for enduro riding. This red 46-tooth sprocket is 100% machined: no stamping or grinding, for precise finishing and sharp tooth edges. The additional heat treatment applied to the 7075 T651 alloy limits deformation and allows for optimal tooth thickness — ensuring maximum contact between the tooth and chain on demanding terrains.
Designed for enduro riders who want a lightweight, precise, and durable part for tough terrain, this sprocket fits 520 transmissions. Simple installation for standard replacement on compatible models. Top compatibilities: BETA RR 480 EFI Racing (E6) 2018, BETA RR 480 EFI (E6) 2018, and BETA RR 430 EFI (E6) 2018.
