Now you don't have to brake the bank to dial in your transmission. In the past to get your variator performing just right you had to buy multiple sets of rollers, each costing you anywhere from $15-$25-maybe more!

To solve this problem we bring you a tuning kit containing a wide range of weights, allowing you to try different options before you buy your final set.

This kit contains 16x13mm rollers in the following weights:
3, 4, 5, 6, 7, and 8 gram

By mixing, and using 3 rollers of 2 different weights, this kit allows for testing with 11 different roller weights.

Note:These rollers are designed for tuning purposes only and shouldn't be used for long term use. Once you have determined the appropriate weight for your set up you should buy a high quality roller for permanent use.

This part fits on:
All scooters and variators that use the 16x13mm roller size
