Engineered by Derbi for the sport motorcycle segment, the 2008 Derbi GPR Racing 50 Race Replica relies on a 49.9 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 39.9 x 40.0 mm (1.6 x 1.6 inches) with a 11.5:1 compression ratio.
On the scales, the GPR Racing 50 Race Replica measures 116 kg (256 lbs) dry. Rider ergonomics and chassis geometry center around a 1,311 mm (51.6 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
