2023 Rieju MRT 50 Pro Technical Analysis & Specification Breakdown

At the heart of the 2023 Rieju MRT 50 Pro enduro - offroad motorcycle, Rieju features a 50 cc (3.1 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches).

On the scales, the MRT 50 Pro measures 85 kg (187 lbs) dry. Rider ergonomics and chassis geometry center around a 890 mm (35 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 6.32-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
