I raced motocross around Kansas about 5 years ago on my Polaris Predator. That machine is long gone and has been replaced by my 250r. I love this machine, and have no desire to get rid of it. That is where my question starts. I want to start racing again, but is my R good enough to keep up with the 450's. I want to loose because I suck, not because my machine is under powered.
