Moose Offroad Hard Rear Sprocket - PARTS (ref. 1211-BET-49-13)
Rear sprocket specifically designed for enduro, made from 7075 T651 aluminium with additional heat treatment. This sprocket combines full machining (100% machined, no stamping or grinding) and a carefully studied tooth geometry: optimal tooth thickness for maximum contact between the tooth and the chain, limiting pressure points and promoting even wear.
Ideal for riders looking for a lightweight, precise crown with optimised tooth design for effective chain engagement. Reference compatible with several BETA RR models (e.g. RR 480 EFI Racing, RR 430 EFI, RR 390 EFI - E6 generation 2018), please check the exact compatibility with your motorcycle before installation.
