2011 Rieju Marathon 450 Technical Analysis & Specification Breakdown

Built around Rieju's enduro - offroad motorcycle platform, the 2011 Rieju Marathon 450 utilizes a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 95.0 x 63.4 mm (3.7 x 2.5 inches).

On the scales, the Marathon 450 measures 132 kg (291 lbs) wet (curb). 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 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
