Description
Rotational mass is the enemy of acceleration and handling—especially on competitive ATVs where every tenth of a second counts. The Renthal 38T Ultralight Rear Sprocket cuts that mass by 66% compared to steel, translating directly to sharper throttle response and easier weight transfer through technical terrain. Built from CNC-machined 7075-T6 aluminum with self-cleaning mud grooves, this sprocket delivers the durability of premium racing components without the weight penalty.
This is a bolt-on upgrade for Honda ATV platforms. Verify your specific model’s compatibility before ordering, as fitment varies across the TRX lineup.
