Positioned in Suzuki's cross - motocross motorcycle lineup, the 2010 Suzuki RMZ 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 96.0 x 62.1 mm (3.8 x 2.4 inches) with a 12.2:1 compression ratio.
On the scales, the RMZ 450 measures 123.5 kg (272 lbs) wet (curb).
