2008 GAS GAS SM 450 Supermotard Technical Analysis & Specification Breakdown
Engineered by GAS GAS for the super motard motorcycle segment, the 2008 GAS GAS SM 450 Supermotard relies on a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 97.0 x 60.8 mm (3.8 x 2.4 inches).
On the scales, the SM 450 Supermotard measures 119 kg (262 lbs) dry. Rider ergonomics and chassis geometry center around a 900 mm (35.4 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 6.7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
