Engineered by Suzuki for the cross - motocross motorcycle segment, the 2017 Suzuki DR-Z125 utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 56.9 x 46.8 mm (2.2 x 1.8 inches) with a 9.5:1 compression ratio.
On the scales, the DR-Z125 measures 87 kg (192 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,245 mm (49 in) wheelbase engineered for quick, flickable steering geometry. The 4.8-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
