Engineered by Rieju for the enduro - offroad motorcycle segment, the 2021 Rieju MR 300 Ranger utilizes a 299.3 cc (18.3 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 72.0 x 72.0 mm (2.8 x 2.8 inches).
On the scales, the MR 300 Ranger measures 105 kg (231 lbs) dry. Rider ergonomics and chassis geometry center around a 925 mm (36.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,475 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 8.9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
