For Derbi the name Senda has always meant a road that leads to freedom, with high range off-road models which, in the DRD (Derbi Racing Development) version are the top of their category as far as concerns the equipment and technology level together with the application of cutting edge solutions, typical of bigger engine displacement models only. Already dominating the streets in the 50 cc and 2S category, in the 125 4S sector they are the top in their engine displacement range and, as usual, they are available in the R (Enduro) and SM (Motard) versions.
Both models have the same chassis, a sophisticated high-resistant dual beam steel chassis derived from the one used in the Terra family. Although the bike has a sports character and extensive travel suspensions (245 mm at the front and 225 at the back), particular attention has been given to aspects such as saddle height which, thanks to the Freestyle inspired design, is lower compared to other brands (905 mm for the R version and 880 mm for the SM version). With these features, combined with a record weight for its category – 124 Kg only – it was possible to further enhance the daily functions of both models. Top quality components are used for both the front and rear suspensions, as usual for the Derbi DRD range. A 41 mm Paioli upside-down fork is used at the front while the steel rear fork at the back exploits a progressive Pro-Link link rod system to which an Ollé single shock absorber is fixed with separate gas tank and adjustable spring preloading.
Wheels and brakes make the difference between the R and SM versions. While the Enduro R has 21″ at the front and 18” at the back off-road tyres, the Motard SM has 17″ street rims on both wheels with street tyres. There are differences in the complete braking system as far as concerns the front disc, with a Galfer Wave profile and 260 mm for the off-road model and an oversized 300 mm traditional disc for the street version. Both models boast powerful and reliable twin-plunger calliper and front radial mounting, while at the back they both have a Galfer Wave 220 mm disc with single plunger calliper.
