Athena Aprilia SR 125 Variator Rollers Kit (19x17 gr.15.5) - Set of 6

This is a set of 6 variator rollers from Athena, specifically for the Aprilia SR 125. These rollers are sized 19x17mm and weigh 15.5 grams each. They are a key part of your scooter's continuously variable transmission (CVT), controlling how your scooter shifts gears to optimize engine performance for acceleration and top speed.

Athena uses a careful selection of materials and a special design for the roller side rails. This helps to reduce power loss and improve torque transfer, leading to a more responsive feel and better overall performance from your scooter's drivetrain. Replacing worn rollers with a fresh set can make a noticeable difference in how your scooter accelerates and reaches its top speed.
