Renthal Ultralight Rear Sprocket - KTM 65 SX / Husqvarna TC 65 / GasGas MC 65 (2025-2026)

The Renthal Ultralight Rear Sprocket is engineered to reduce rotating unsprung weight, allowing your KTM 65 SX, Husqvarna TC 65, or GasGas MC 65 to transfer power to the ground more efficiently.

CNC-machined in the UK from high-strength 7075 T6 aerospace-grade aluminum, this sprocket is 66% lighter than steel while maintaining the rugged durability required for championship-level motocross. Featuring Renthal's patented self-cleaning mud grooves, it prevents dirt buildup between the teeth, significantly extending the life of both your sprocket and chain.
