At the heart of the 2008 PRC (Pro Racing Cycles) RR-65 cross - motocross motorcycle, PRC (Pro Racing Cycles) relies on a 65 cc (4 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 45.0 x 40.8 mm (1.8 x 1.6 inches).
On the scales, the RR-65 measures 52.6 kg (116 lbs) dry. Rider ergonomics and chassis geometry center around a 819 mm (32.2 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,167 mm (45.9 in) wheelbase engineered for quick, flickable steering geometry.
