Engineered by Derbi for the minibike, cross motorcycle segment, the 2007 Derbi Dirt Kid utilizes a 49.9 cc (3 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 4.6 HP (3.4 kW), transferring power to the rear wheel through a 1-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.0 mm (1.5 x 1.6 inches) with a 12.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 995 mm (39.2 in) wheelbase engineered for quick, flickable steering geometry. The 2.3-liter (0.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
