Athena Derbi 02 Bullet 50 Variator Rollers Kit (19x15.5 gr.6.4) - Set of 6

This kit includes six variator rollers, each measuring 19x15.5mm and weighing 6.4 grams. These rollers are a key component in your scooter's automatic transmission, often called a CVT (Continuously Variable Transmission). They work with the variator assembly to change the gear ratio as you accelerate, affecting both your scooter's acceleration from a stop and its top speed.

Athena has updated its range of variators and their components for scooters. These rollers are made with careful material selection and a special design on the roller side rails. This design aims to optimize your scooter's performance, helping to increase speed and acceleration while minimizing power loss. By ensuring the rollers move smoothly within the variator, they help maintain torque and deliver a more responsive feel.
