Rear Sprocket MOOSE OFFROAD HARD - PARTS (ref. 1211-895-49-10): aluminium crown designed for motocross use. Machined from 100% 7075 T651 aluminium, it features a heat treatment that reduces deformation and allows for an optimal tooth thickness compared to common 7075 T6 crowns. Designed to ensure maximum contact between the tooth and chain, it fits on 428 pitch transmissions.
This crown is aimed at motocross riders looking for a lightweight and precise part for their transmission. Full machining avoids weaknesses associated with stamping or grinding, while the optimised tooth thickness maximises the chain's contact surface for consistent performance on track. Changing the rear sprocket remains the most straightforward solution to adjust the gear ratio according to the layout or riding style.
Specifically suitable for 85 cc models: Husqvarna TC 85 19/16 (2021), KTM SX 85 19/16 (2018) and Husqvarna TC 85 17/14 (2021). Check the chain pitch and compatibility of the mounting before installation.
