Built around Derbi's super motard motorcycle platform, the 2008 Derbi Senda X-treme 50 SM features a 49.9 cc (3 cu in) liquid-cooled single cylinder, two-stroke configuration. 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.
On the scales, the Senda X-treme 50 SM measures 97 kg (214 lbs) dry. 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 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
