2021 Derbi Senda Racing 50 SM Technical Analysis & Specification Breakdown
Positioned in Derbi's super motard motorcycle lineup, the 2021 Derbi Senda Racing 50 SM utilizes a 50 cc (3.1 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 11.5:1 compression ratio.
On the scales, the Senda Racing 50 SM measures 104 kg (229 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 865 mm (34.1 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,390 mm (54.7 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank paired with a rated consumption of 3.14 L/100 km provides an estimated theoretical range of roughly 223 km (139 miles) between fill-ups.
