A day of testing with Doug Dubach

Doug Dubach and Dubach Racing Development may be best known for producing top-level Yamaha four-stroke exhaust systems, but the truth of the matter, is that DR.D produces a wide range of aftermarket products for all bike brands, shapes, and sizes.

As has always been the case, everything that DR.D brings to market is developed, tested, and approved by Dubach himself. From hour meters, to radiator lowering kits, to exhaust systems, nothing makes it through the R&D stage without the Doctor’s stamp of approval.
