Sierra Old Timers Motorcycle Club is a Northern California non-profit group dedicated to provide and encourage motocross events for older riders.
We have classes for riders of all skill-levels, from novice to master, on the international circuit.
It’s not just about competition here!
We are a diverse group of individuals
with at least one thing in common...
We Love Motocross!
