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.
