Engineered by Derbi for the naked motorcycle segment, the 2007 Derbi GPR Nude 50 pairs a 49.9 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a 11.5:1 compression ratio.
Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with 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.
