Replace the rear sprocket with a road and workshop tailored part: this Moose Offroad Hard - Parts sprocket is machined for demanding riders. Made from 7075 T651 aluminium with additional heat treatment, it limits deformation and offers a tooth thickness superior to standard 7075 T6 sprockets. Designed for precise chain engagement, it is 100% machined — without stamping or grinding — for a clean finish and consistent geometry.
Versatile, this sprocket is suitable for Trail/Adventure, Enduro, Motocross, Supermoto, Roadster, Sport, Trial, and Quad practices. It will particularly fit the top 3 compatible machines: GAS-GAS EC 300 RACING (2017), SHERCO SEF-R 450 (2015), and HUSQVARNA NUDA 900 R ABS (2013). Before installation, check the compatibility of the pitch and chain length. A well-machined sprocket improves transmission precision and the tooth/chain contact for a sharper control feel on all types of terrain.
