Clean State of the Art Service Department
At WMR Competition Performance we are experts at motocross engine, suspension and chassis modifications. With thousands of hours building and testing every major brand of MX bike we know how to get the most out of your machine. We build motors and suspension for customers all over the world, one at a time. We speak to the rider or mechanic to determine the best modification for that particular bike, and then we go to work. WMR has built more four stroke motors than most any other race shop in the country, we even make custom valve train components that are designed to match perfectly with our head modifications. Using computer technology to map every two stroke cylinder, we carefully port and polish for countless hours until we are completely happy with the final result. After porting thousands of cylinders we know when it's perfect, and that's when it's done. Through testing the team bikes we learn so much, and we take that knowledge and experience back to the motor room. There is always room for improvement so we are constantly tweaking our specs to make sure you are getting the very latest technology. If you are sick of the production line motor builders and are ready for one on one personal attention call us today.
WMR COMPETITION PERFORMANCE offers complete motocross services. With a full machine shop on site there is nothing we can't repair or fabricate for your off road motorcycle. Even though we are known for our motor and suspension work that's not all that we do. From the ground up we can handle everything you need for your bike in time for your next race. At WMR we take pride in being able to do it all!
