Engineered by KTM for the atv motorcycle segment, the 2009 KTM 450 XC ATV pairs a 447.9 cc (27.3 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 89.0 x 72.0 mm (3.5 x 2.8 inches) with a 11.0:1 compression ratio.
On the scales, the 450 XC ATV measures 163 kg (359 lbs) dry. Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 13.4-liter (3.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
