Rear Sprocket / Crown MOOSE OFFROAD HARD - PARTS — Manufacturer reference: 1211-897-48-12
Rear crown made of 7075 T651 aluminium, specially machined for the demanding transmissions of enduro, motocross, quad and supermoto. The additional heat treatment applied to the alloy reduces deformation and allows for an optimised tooth thickness compared to the thinner 7075 T6 versions. 100% machined: no stamping or grinding, for a precise and consistent tooth finish.
The tooth geometry is designed to ensure optimal contact between the tooth and chain, promoting smooth transmission and even chain wear. Its machined finish provides precise engagement and a neat aesthetic for competition and leisure-oriented machines. Blue colour available to customise the rolling train without compromising the strength of the component.
Suitable for off-road practices and models with a 520 chain. Examples of compatible motorcycles: HUSQVARNA FC 450 (2021), KTM EXC 300 TPI Sixdays (2019), HUSABERG FE 501 (2015).
