Company History
Under the PRC banner, small American race shops supplied frames, swingarms, and setup parts that turned production motorcycles into sharper tools for road racing. The focus was always lap-time per dollar: reduce weight, improve geometry, and provide setup notes so privateers could reproduce results without factory backing. PRC’s influence shows up in garages—jigs, welds, and alignment practices that trickled through club paddocks—more than in showrooms. Historically, PRC represents the unsung engineering strata that elevates an entire sport: the people who make bikes finish races, teach riders what ‘good’ feels like, and refine ideas that manufacturers later adopt.
