2004 GAS GAS SM 250 Technical Analysis & Specification Breakdown
At the heart of the 2004 GAS GAS SM 250 super motard motorcycle, GAS GAS utilizes a 250 cc (15.3 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 66.4 x 72.0 mm (2.6 x 2.8 inches).
On the scales, the SM 250 measures 101 kg (223 lbs) dry.

The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
