2006 UM Comet 125 SS Technical Analysis & Specification Breakdown
Engineered by UM for the scooter motorcycle segment, the 2006 UM Comet 125 SS relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 53.3 x 58.8 mm (2.1 x 2.3 inches) with a 9.2:1 compression ratio.
On the scales, the Comet 125 SS measures 97 kg (214 lbs) dry.

The 4.73-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
