At the heart of the 2008 Derbi Mulhacen 659 naked motorcycle, Derbi pairs a 659.7 cc (40.3 cu in) liquid-cooled engine architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 100.0 x 84.0 mm (3.9 x 3.3 inches) with a 10.0:1 compression ratio.
On the scales, the Mulhacen 659 measures 165 kg (364 lbs) dry. Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1 mm (0 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.
