After seeing the lack of availability and understanding of the RZR 170 Components, and having a lived the life of a pit Dad working on CVT mini quads, I decided to find the best parts available for upgrading the CVT system without all the guess work, SBR has eliminated the guess work and get you moving in the right direction. Email any question and we will do our best to help. Don't get caught up buying parts from people who don't really understand what the CVT is doing and how to correct issues for each car individually, its one thing to just plug and play, another to tune to your set up and driver to maximize the benefits, one size rarely fits all and SBR kits Matched with know how will get you there!
