When it comes to adjusting your variator, there is no need to have tons of roller weights on hand for tuning. This roller weight kit includes 12 sets of 3 rollers for a total of 36 roller weights to adjust and fine-tune your variator.

Directions for Use: Combine 2 sets of rollers in an alternating pattern, for example: 3 x 10g & 3 x 11g rollers (alternating weights in variator) gives you a 10.5g roller set.

Please Note: You must install these weights in an alternating pattern, otherwise a severe imbalance in the variator will occur. These rollers are designed for tuning purposes only and we recommend that they are not used for long term use. Once you have determined the appropriate weight for your set up you should buy a complete roller set for permanent use.

Roller Diameter: 18mm

Frequently Asked Questions

When will my order be shipped and how long does delivery take?

Orders containing in-stock items typically ship within 3–5 business days. Orders that include assembly will require 7–10 business days to prepare. Please note that during the holiday season (Thanksgiving through Christmas), processing times may be longer due to high order volume. Once your order has shipped, you’ll receive an email with tracking information. Most orders are shipped via Less Than Truckload (LTL) freight and generally arrive within 3–7 business days. Deliveries to remote areas (such as mountains, forests, valleys, or islands) may take longer. You can check the estimated delivery date on the carrier’s website using the tracking number we provide.

How your vehicle is shipped?

Unless otherwise noted, the vehicles we offer are shipped crated or on a pallet and do not come assembled unless you’ve selected our assembly service. Assembly typically requires a few basic tools and mechanical knowledge. If you're not confident in your ability to safely assemble a high-speed off-road vehicle, we strongly recommend selecting professional assembly or having it assembled by a local mechanic.

What does 95% or 98% Assembly Mean? What do I need to assemble if shipped in crate?

For shipping safety, most vehicles cannot be fully assembled prior to delivery.

Minor assembly is required—this typically includes installing mirrors, connecting the battery, adjusting handlebars, and other small components. Before operation, please ensure all screws and fasteners are tightened, engine fluids are at proper levels, and the battery is fully charged. Your factory warranty remains valid right out of the box.
