    We are a passionate group of riders, racers, and entrepreneurs that are passionate about all things motocross

    Dennis Stapleton Jr.



    My racing career started at the age of 12 in northern California, After my first race, I was hooked and there was no turning back! I turned pro in 1997 after racing Loretta’s, then graduated to the nationals full time. I became a test/development rider for the Factory Husqvarna team in 2000 and was able to race 6 nationals on their 125 two-stroke. Since then, I have raced as much as possible while becoming a full time test rider for Motocross Action Magazine. In 2012, I got serious about riding schools and motocross vacations, so I started StapoMx. Due to my traveling all over the world, I was able to meet some great people in other countries and now I have them travel to come stay with me in Southern California. My students along with my friends from other countries are living the dream enjoying the mecca of motocross in sunny southern California.

    I grew up around dirt bikes. Camping and riding throughout the desert was our regular family time on all holidays and weekends. My first track experience was in 2014 and I fell in love with it. I participate in local races and have a great time riding with my friends regularly. I started helping Dennis with the paperwork side of his business in 2016 and enjoy working with Dennis and his dad on a part time basis. My full time job is at a company called NETSTOCK where I am the Finance Operations Supervisor, which provides me with the ability to balance the two jobs.­
