Description
If you’re running a 428 chain on your dirt bike or ATV, sprocket wear directly impacts throttle response and overall drivetrain efficiency. The Renthal 49T Blue Rear Sprocket cuts weight by 66% compared to steel alternatives, translating to quicker acceleration and reduced unsprung mass—critical gains in off-road riding. Its CNC-machined 7075-T6 aluminum construction and self-cleaning mud grooves ensure consistent power delivery lap after lap, even in the worst conditions.
