2006 PRC (Pro Racing Cycles) LX-RR Works Technical Analysis & Specification Breakdown
At the heart of the 2006 PRC (Pro Racing Cycles) LX-RR Works cross - motocross motorcycle, PRC (Pro Racing Cycles) utilizes a 50 cc (3.1 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 13.5 HP (9.9 kW) at 14,000 rpm while maximum torque reaches 8.2 Nm (6 lb-ft) at 11,200 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 270 HP per liter and a 2,800 rpm working window between peak torque (11,200 rpm) and peak power (14,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the LX-RR Works measures 36 kg (79 lbs) dry. Rider ergonomics and chassis geometry center around a 660 mm (26 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,016 mm (40 in) wheelbase engineered for quick, flickable steering geometry.
