Ideal for standard replacement or for modifying the gearing, this sprocket meets the demands of 520 transmissions for off-road use. Its mud-resistant profile helps limit the accumulation of mud between the chain and the sprocket for more consistent performance in muddy conditions.

Material: C49 carbon steel
Color: black
Number of teeth: 50
Chain pitch: 520
Type: standard — direct mount on hub

Designed for off-road sessions, this JT sprocket is aimed at motocross and enduro riders looking for a robust and easy-to-install component. Compatible model examples: YAMAHA YZ 450 F (2026), FANTIC XX 125 (2022), GAS GAS EC 300 F (2015). When replacing, check the wear of the sprocket and the condition of the chain, and adhere to the manufacturer's torque specifications for safe transmission.
