Moto and me go way back to the days of High School Motocross in the late 70's. Corona Raceway was the local hot spot and pro riders like Staten, Bauer, and Stout were regulars.
I raced hard and made the pro class, retiring in my late 20's and still riding because I can't stop.
I've been a design guy here at MSRMX for a crap load of years and still going strong. Look for #6 on a white MSRMX CRF450 at a local so. cal. track near you.
