Built around Suzuki's cross - motocross motorcycle platform, the 2005 Suzuki RM-Z 450 features a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 95.5 x 62.8 mm (3.8 x 2.5 inches) with a 12.1:1 compression ratio.
On the scales, the RM-Z 450 measures 101 kg (223 lbs) dry. Rider ergonomics and chassis geometry center around a 995 mm (39.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,486 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
