2025 GAS GAS MC 85 17-14 Technical Analysis & Specification Breakdown
Built around GAS GAS's cross - motocross motorcycle platform, the 2025 GAS GAS MC 85 17-14 relies on a 84.9 cc (5.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, maximum torque reaches 85 Nm (62.7 lb-ft) at 2,025 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. 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 MC 85 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 5.4-liter (1.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
