Get to Know Us
FatPipe Racing started in 2020 in a Pandemic shortened race season with one solo RD200 race bike, my very best friend from childhood, Cliff Ginger and his "modern" SV650, and the thought that maybe we'd do a couple of races for Old Time's sake. Three and a half seasons later, the addition of my great friend/partner/sidecar monkey, Adam Bower, and a whacked up dream to race Vintage 2-stroke sidecars, and here we are. We race all over the country and hope to add Canada next season, we hand build expansion chambers, we carefully build all manner of two-stroke race and road engines, Adam alone does some sweet vintage scooters, and we even hand craft a few complete race bikes. We would love to have you join us on the journey to preserve all that is so good about the two-stroke motorcycle.
