MOOS OFFROAD HARD Rear Sprocket - PARTS (Manufacturer ref: 1210-897-52-13X)
Designed for off-road, this dual sprocket combines lightness and robustness to tackle enduro and motocross sessions. The inner ring made of 7075-T6 aluminium reduces the rotating weight on the rear wheel, while the outer ring made of reinforced steel provides the necessary durability against the demands of the terrain.
The "dual" design allows for better longevity than fully aluminium rear sprockets while remaining significantly lighter than a solid steel sprocket. The self-cleaning grooves between each tooth limit the accumulation of mud and debris, preserving the chain and teeth during muddy or sandy outings.
Ideal for demanding riders who want to optimise the responsiveness and reliability of the transmission on difficult terrains. Compatible with many motocross and enduro models — including the GAS‑GAS EC 350 F (2026), EC 300 (2026), and MC 450 F Prado Edition (2025) — this sprocket is a relevant choice to strengthen the rear of your motorcycle without unnecessarily adding weight to the wheel.
