2008 Rieju RS2 Pro 125 Technical Analysis & Specification Breakdown

Positioned in Rieju's sport motorcycle lineup, the 2008 Rieju RS2 Pro 125 relies on a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 54.0 x 54.0 mm (2.1 x 2.1 inches).

On the scales, the RS2 Pro 125 measures 109.5 kg (241 lbs) dry. Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 10.4-liter (2.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
