2002 GAS GAS EC 250 Technical Analysis & Specification Breakdown
Engineered by GAS GAS for the enduro - offroad motorcycle segment, the 2002 GAS GAS EC 250 utilizes a 249.3 cc (15.2 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 49.8 HP (36.4 kW) at 8,600 rpm while maximum torque reaches 45.6 Nm (33.6 lb-ft) at 7,628 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 199.8 HP per liter and a 972 rpm working window between peak torque (7,628 rpm) and peak power (8,600 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
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.
