Engineered by KTM for the cross - motocross motorcycle segment, the 2013 KTM 85 SX 17-14 relies on a 84.9 cc (5.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 47.0 x 49.0 mm (1.9 x 1.9 inches).
Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, 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.
Within MotoLibrary's KTM archive, this model family spans 17 indexed model years from 2007 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
