Positioned in KTM's cross - motocross motorcycle lineup, the 2025 KTM 85 SX 17-14 utilizes a 84.9 cc (5.2 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 47.0 x 40.8 mm (1.9 x 1.6 inches).
On the scales, the 85 SX 17-14 measures 68 kg (150 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 1,282 mm (50.5 in) wheelbase engineered for quick, flickable steering geometry. The 5.24-liter (1.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
