At the heart of the 2003 Suzuki RM 85 cross - motocross motorcycle, Suzuki features a 84.7 cc (5.2 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 48.0 x 46.8 mm (1.9 x 1.8 inches) with a 9.5:1 compression ratio.
On the scales, the RM 85 measures 65 kg (143 lbs) dry. 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.
