Technical Overview
2011 GAS GAS EC 125 Racing Technical Analysis & Specification Breakdown
Engineered by GAS GAS for the enduro - offroad motorcycle segment, the 2011 GAS GAS EC 125 Racing relies on a 124 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 54.0 x 54.5 mm (2.1 x 2.1 inches).
On the scales, the EC 125 Racing measures 105 kg (231 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 940 mm (37 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,475 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.
