It has been seventeen years since Yamaha first introduced the YZ400F to the sport of Motocross back in 1998.
A few years prior, we had already begun research and development towards this new type of racing technology
that would inevitably change the sport.
It is now 2015, and research and development still continues to be an essential part of our daily routine. Our
exhaust systems are developed in-house and carefully tested with the help of our race team and support riders
to ensure you are getting the very best product we can create to help separate you from your competition on
the race track.
Whether you plan to take on the professional circuit, amateur events, off-road races, UTV/ATV trails or you
enjoy riding a fun loop in the desert with your buddies, we have just the type of exhaust you are looking for.
