Yoshimura has been working extensively with OE’s and factory racing teams to develop racing-oriented parts that can also benefit the weekend warrior. Because we take racing seriously, we have utilized the most technologically advanced equipment available. Through the use of high-tech data acquisition and GPS tracking technology, similar to those used in Formula One racing, we’ve developed the best-performing products in the industry. With additional input from our racers, we have tuned everything from intakes to exhausts, and engines to engine management systems. Yoshimura is proud to play a role in the continuing development of UTV performance and racing.
