Built around PRC (Pro Racing Cycles)'s cross - motocross motorcycle platform, the 2007 PRC (Pro Racing Cycles) LX-R pairs a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 39.5 x 40.0 mm (1.6 x 1.6 inches) with a 8.9:1 compression ratio.
On the scales, the LX-R measures 45 kg (99 lbs) dry. Rider ergonomics and chassis geometry center around a 648 mm (25.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 990 mm (39 in) wheelbase engineered for quick, flickable steering geometry.
