Description

Unsprung weight directly impacts your bike's acceleration, braking response, and handling precision—and aluminum sprockets eliminate unnecessary rotational mass at one of the most critical points in your drivetrain. The Renthal Ultralight 45T reduces sprocket weight by a significant margin compared to stock steel, translating to quicker throttle response and improved chassis feedback through corners. If you're serious about extracting every tenth from your Aprilia, this CNC-machined upgrade is a straightforward bolt-on that delivers measurable performance gains.
