Jasil Scooter Performance

Jasil is a scooter performance parts maker, with Hitech crankshafts, SV1 variators and final drive gear kits making up most of the range here.

These are build parts, not service parts. A variator changes how the scooter uses its revs and a gear kit changes where it ends up, so the two want to be chosen together. Tell us the scooter and whether you care about the launch or the top end and we will spec it.

Frequently asked questions

What does a variator change on a scooter? It controls how the belt sits on the pulleys as revs rise, which sets how quickly the scooter gets moving and where it tops out. It works with the rollers and spring.

Should I change the gear kit and variator together? If you are chasing a specific result, yes. A variator alone changes the launch and a gear kit changes the final ratio, and one without the other often undoes the gain.

Do you offer free shipping in Canada? Yes, on orders over $279.99.
