2008 GAS GAS MC 125 Cross Technical Analysis & Specification Breakdown

At the heart of the 2008 GAS GAS MC 125 Cross cross - motocross motorcycle, GAS GAS pairs a 124 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 45.0 x 40.8 mm (1.8 x 1.6 inches).

On the scales, the MC 125 Cross measures 92 kg (203 lbs) dry. Rider ergonomics and chassis geometry center around a 945 mm (37.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,460 mm (57.5 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
