Built around Rieju's scooter motorcycle platform, the 2015 Rieju Urban Blast relies on a 50 cc (3.1 cu in) air-cooled single cylinder, four-stroke powerplant. 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 Urban Blast measures 93 kg (205 lbs) dry. Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,276 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
