Description
If you’re running a 42-tooth rear sprocket on your Husaberg or KTM, you’re already optimizing for acceleration and low-end grunt—but a stock steel sprocket is costing you performance through unnecessary weight and accelerated wear. The Renthal 42T rear sprocket cuts that dead weight by 66% with its 7075-T6 aluminum construction, giving you sharper throttle response and reduced unsprung mass that translates directly to better handling and faster lap times. The precision-machined mud grooves ensure consistent engagement and longevity even in the harshest off-road conditions, so you can focus on riding instead of maintenance.
