Built around Suzuki's cross - motocross motorcycle platform, the 2008 Suzuki RM-Z250 pairs a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 77.0 x 53.6 mm (3.0 x 2.1 inches) with a 13.4:1 compression ratio.
On the scales, the RM-Z250 measures 106 kg (234 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 955 mm (37.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
