2010 UM REV 125 Technical Analysis & Specification Breakdown

At the heart of the 2010 UM REV 125 allround motorcycle, UM pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 56.0 x 49.5 mm (2.2 x 1.9 inches) with a 9.0:1 compression ratio.

On the scales, the REV 125 measures 113 kg (249 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 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
