Description
If you're running KTM 85 SX or 105 SX, the stock rear sprocket is costing you performance. The Renthal 47-tooth sprocket cuts unsprung weight by 66% compared to steel alternatives, directly improving acceleration and mid-range handling on technical terrain. With self-cleaning mud grooves and 7075-T6 aluminum construction, you get durability that matches the demands of competitive off-road riding without the weight penalty.
This is a bolt-on replacement engineered for precision. The CNC-machined tooth profile ensures smooth, consistent power transfer to the chain, while the specialized mud grooves prevent buildup that can cause drag and accelerate wear. Whether you're racing or training, reducing rotational mass at the rear wheel translates to faster response and better control.
