2009 GAS GAS EC 515 FSR Technical Analysis & Specification Breakdown
Built around GAS GAS's enduro - offroad motorcycle platform, the 2009 GAS GAS EC 515 FSR relies on a 515 cc (31.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 100.0 x 62.6 mm (3.9 x 2.5 inches).
On the scales, the EC 515 FSR measures 118 kg (260 lbs) dry. 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 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
