The Derbi Senda is a Supermotard made by Spanish company Derbi. It is one of the most popular bikes made by Derbi due to its appeal to young riders, its styling and its amazing tuning possibilities.
History The Derbi Senda was launched in 1994, and throughout the 2000s, it went under several design evolutions. The early models featured a steel perimeter frame, which was later refined to improve rigidity and handling. In 2006, Derbi introduced a significant restyling, giving the bike sharper bodywork and a more modern aesthetic that aligned it with larger enduro and supermoto machines.
The Senda is widely recognized for its two main variants: Senda R (Enduro): Designed for off-road use, featuring off-road tires and long-travel suspension. Senda SM (Supermotard): Designed for asphalt, featuring road tires and stiffer suspension settings.
Engine
The bike itself uses an EBS/EBE, D50B0 or D50B1 engine which produces a staggering 5bhp. The Derbi Senda is identically constructed as the Gilera SMT 50. Between 1995 and 2005, Derbi was produced with an EBS / EBE engine, and after 2005, D50B0 / D50B1 engines were used until 2023.
