Athena Derbi 02 Bullet 50 Variator Rollers Kit (19x15.5 gr.3.5) - Set of 6

If you're looking to get the most out of your Derbi 02 Bullet 50's acceleration and top speed, a fresh set of variator rollers is a smart move. These rollers are a key part of your scooter's continuously variable transmission (CVT), and worn-out ones can really hurt performance. This kit from Athena includes six rollers, each measuring 19x15.5mm and weighing 3.5 grams, which is a common setup for this model.

Athena uses careful material selection and a special design for the roller side rails to help optimize your scooter's power delivery. This means you should see improved acceleration and a higher top speed, with less power lost in the drivetrain. Replacing these rollers is a straightforward job for most DIYers, and it can make a noticeable difference in how your scooter feels on the road.
