Manufacturer reference: 1211-897-47-14 — MOOSE OFFROAD HARD rear sprocket designed for Enduro, Cross, Quad, and Supermoto practices. This 7075 T651 aluminium crown benefits from an additional heat treatment that limits deformation and allows for an optimal tooth thickness compared to the generally thinner 7075 T6 versions.
Fully machined, this crown features a tooth thickness designed to maximise contact between the tooth and the chain, ensuring consistent engagement of the transmission. Its robust design in high-strength aluminium offers an excellent weight/strength compromise for off-road and track constraints. Ideal as a replacement for transmissions equipped with 520, it is particularly compatible with KTM EXC 300 TPI Sixdays (2019), HUSQVARNA FE 501 (2018), and HUSABERG FE 501 (2015) models according to manufacturer compatibility.
Chosen by riders seeking precision and reliability on varied terrains, this crown can be easily mounted in place of the original element suited for the 520 pitch.
