Variator Weight Tuning Kit Polini
Description
Polini CVT tuning set
The Polini weight sets consist of 4 different sets of weights (6 pieces each), allowing precise CVT adjustment. This tuning set is perfect for anyone looking to optimize their scooter's performance.
The weights save money, as you don't have to buy several sets of roller weights, and the plastic caps can also be purchased separately if replacements are needed.
Important: These tuning rollers are not intended forlong-term use. For daily riding, we recommend switching to pre-coated standard weights.
Advantages of Polini tuning kits:
Determine the optimum roller weight for your variator and setup
Ideal for testing and fine-tuning engine performance
Cost-saving - no need to buy multiple roller sets
Durable plastic box for secure storage
Pro tip
Lighter weights result in shorter gear ratios; heavier ones in longer ratios. Always start testing with the heaviest weights and gradually go lighter until the engine revs smoothly and doesn’t lose RPMs on inclines.
Make sure to fill and place the rollers evenly to avoid imbalance.

CVT Weights
CVT roller weights, also called variator weights, play an essential role in the performance of scooters, maxiscooters and mopeds with CVT transmissions.
The CVT is responsible for transmitting engine power to the rear wheel of the scooter. It consists of several components, including the variator rollers. These roller weights, which are usually made of plastic or metal, sit in special tracks in the variator. Weight and diameter can vary depending on the scooter model and manufacturer.
Lighter or heavier weights?
The right weights can noticeably improve the performance of your scooter. The weight of roller weights has a direct effect on acceleration and top speed. Basically, lighter rollers lead to improved acceleration, while heavier rollers increase top speed. However, if the rollers are too light they may improve acceleration too much at the expense of speed. On the other hand, CVT rollers that are too heavy can improve speed while severely compromising acceleration.
To experiment a bit with different weights and find the best balance, we recommend getting a variator tuning kit with different weights. We also recommend buying a piston stopper or a CVT blocking tool so you can quickly disassemble and reassemble the variator.
