At the heart of the 2011 KTM 85 SX 17-14 minibike, cross motorcycle, KTM features a 84.9 cc (5.2 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 47.0 x 49.0 mm (1.9 x 1.9 inches).
On the scales, the 85 SX 17-14 measures 66 kg (146 lbs) dry. Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
