What We Offer

Mossy Rock Trials became a reality in 2011 as a means to get riders the local support that was needed in and around South Central Montana. Founded by Dan Larson as a small repair shop with a few resurrected vintage trials bikes for sale. Larson continues to pursue his passion today by continually practicing trials, dealing bikes, resurrecting used bikes and hosting the annual Whisky Gulch Trials near Whitehall Montana.
