Engineered by Suzuki for the cross - motocross motorcycle segment, the 2006 Suzuki RM-Z 450 pairs a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 95.5 x 62.8 mm (3.8 x 2.5 inches) with a 11.9:1 compression ratio.
On the scales, the RM-Z 450 measures 100 kg (220 lbs) dry. 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 1,480 mm (58.3 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.
