2009 GAS GAS EC 250 Technical Analysis & Specification Breakdown
Engineered by GAS GAS for the enduro - offroad motorcycle segment, the 2009 GAS GAS EC 250 relies on a 249.3 cc (15.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. 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 EC 250 measures 101 kg (223 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 1,476 mm (58.1 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.
