Don't assume a "tune up" will fix the problem.  Sign up for a Diagnosis and guarantee yourself that the money will actually go toward repairing the problem.

Dunlop Pro Dealer Testing



Veteran owned, M Racing is made up of a group of enthusiasts who came together through a genuine sharing of passion.  Opened in 2007, we enjoyed being a presence at AMA, AFM, WERA and WSMC/MotoWest events.  Officially retired from professional racing in 2011, we continue to be enthusiastic about your motorcycle's performance.  Everyone at The M has the benefit of actually riding.  We invite our customers to attend an occasional  track day or riding school with us whenever the opportunity presents itself.  We also try to attend a monthly bike night and put occasional group rides onto our calendar.
