Description
Reducing rotational mass directly improves acceleration and throttle response—critical gains whether you’re racing against the clock or pushing harder on trail rides. The Renthal 43T rear sprocket delivers a measurable weight savings without compromising durability, thanks to its 7075-T6 aluminum construction and anodized hard-coat finish. Self-cleaning mud grooves mean consistent power transfer in any conditions, so you maintain performance mile after mile without premature wear.
