2011 Rieju Marathon Pro 125 Technical Analysis & Specification Breakdown

Engineered by Rieju for the enduro - offroad motorcycle segment, the 2011 Rieju Marathon Pro 125 relies on a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 52.0 x 58.6 mm (2.0 x 2.3 inches).

On the scales, the Marathon Pro 125 measures 107.6 kg (237 lbs) dry. Rider ergonomics and chassis geometry center around a 900 mm (35.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,395 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 6.3-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
