Engineered by Suzuki for the cross - motocross motorcycle segment, the 2007 Suzuki RM 125 pairs a 124 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 54.0 x 54.5 mm (2.1 x 2.1 inches) with a 8.3:1 compression ratio.
On the scales, the RM 125 measures 87 kg (192 lbs) dry. Rider ergonomics and chassis geometry center around a 950 mm (37.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
