Rear sprocket signed MOOSE OFFROAD HARD - PARTS, designed for off-road needs. This rear sprocket/plate made of high carbon C45 steel is CNC machined for tight tolerances and regular tooth geometry, specially suited for 520 pitch transmissions. Its bright zinc finish and black/zinc rendering give it a neat appearance while resisting the rigours of the terrain.
The lightening holes reduce mass without altering the attack geometry of the teeth, useful for enduro outings or motocross days where every gram counts. Designed as a replacement for 520 transmissions, it is aimed at riders looking for a robust and precise part to tackle mud, jumps, and technical sections.
Compatibility examples: YAMAHA YZ 125 (2026), HONDA XR 250 R (ME06) (1989), YAMAHA YZ 125 Monster Energy Edition (2025). Check the pitch and number of teeth required for your motorcycle before installation.
