The Grindstone Compound is a progressive training facility designed for the aspiring motocross athlete.

Grindstone is a launchpad for athletes looking to come to Southern California, offering structured training for both amateurs and pros who are serious about following a professional program and reaching their goals.

Located in Murrieta, California, Grindstone serves as the perfect base camp for riders. We regularly train at local tracks including Fox Raceway, Cahuilla Creek, Perris, Lake Elsinore, and Glen Helen, giving riders consistent access to some of the best facilities in the sport.

Beyond riding, Grindstone provides a complete development program—combining an on-site gym fully equipped for fitness training, tailored workout plans, nutrition guidance—to help every rider progress, perform, and elevate their career to the next level.
