Replace the rear sprocket with a part designed for off-road use: this Moose Offroad Hard-Parts sprocket combines a core made of 7075-T6 aluminium with a high-performance steel crown for a weight/longevity compromise suitable for motocross bikes. The "double crown" design maintains the lightness of an aluminium sprocket holder while benefiting from the wear resistance of steel in the engagement area.
The self-cleaning groove between each tooth limits the accumulation of mud and debris, useful on wet or sandy tracks. Designed for a rear fit with a pitch of 428, this 49-tooth sprocket is particularly aimed at 85 cc machines where agility and reliability are essential.
Common compatibilities: KTM SX 85 and KTM SX 85 (references 2017–2018) as well as HUSQVARNA TC 85 (2018). Ideal for motocross riders looking for a robust, easy-to-maintain crown with a neat appearance.
