Built around Rieju's minibike, cross motorcycle platform, the 2007 Rieju MX 50 utilizes a 49 cc (3 cu in) air-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 39.0 x 41.8 mm (1.5 x 1.6 inches).
On the scales, the MX 50 measures 46 kg (101 lbs) dry. Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,100 mm (43.3 in) wheelbase engineered for quick, flickable steering geometry.
Within MotoLibrary's Rieju archive, this model family spans 3 indexed model years from 2006 to 2010, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
