Engineered by Derbi for the enduro - offroad motorcycle segment, the 2009 Derbi Senda XTreme 50R utilizes a 49.9 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 39.9 x 40.0 mm (1.6 x 1.6 inches) with a 11.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 900 mm (35.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,355 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
