Positioned in Suzuki's cross - motocross motorcycle lineup, the 2021 Suzuki RM85 relies on a 84.7 cc (5.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 48.0 x 46.8 mm (1.9 x 1.8 inches) with a 10.9:1 compression ratio.
On the scales, the RM85 measures 73 kg (161 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,240 mm (48.8 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.
