The Senda DRD, offered as R and SM versions, has always been for young-at-heart riders. The new X-Treme and Racing versions exceed even the wildest expectations: the top in terms of image, technology and sports performance.
For Derbi, the Senda name has always stood for freedom, and has identified upmarket off-road models which, in the DRD (Derbi Racing Development) variant, represent the best that the class has to offer in terms of equipment and finish. The undisputed leaders of the 50 cc class, the R (Enduro) and SM (Supermotard) versions of the Senda DRD represent the essence of off-road riding fun: while the DRD X-Treme and Racing embody the values of the Derbi brand perfectly and cater for the demands of young riders and sports users.
The DRD X-Treme and Racing have been completely revised in terms of technical content and style. The graphics, fairings, headlight and saddle are all new: improvements that make the new DRD family examples of design focused on pure fun.
The new X-Treme variants of the enduro and supermotard versions inherit premium features and components from the Racing version. These include the high power headlight with integrated race number panel and LED taillight, which give the bikes the stylish, high-tech looks of a true pro machine. Then there is the multifunctional digital instrument panel: all the information you need at your fingertips in a compact, lightweight unit.
The robust structure of the double cradle high strength steel gives the Senda DRD models outstanding agility and strength.
The Derbi Senda DRD Racing, which is also available in both S and RM variants, is packed with premium technical solutions and features.
The new Racing boasts top quality suspension components at the front and rear, as you would expect from the Derbi DRD range. At the front is a 41 mm straight fork with a wheel travel of 195 mm (37 mm stanchions and 180 mm wheel excursion for the X-Treme version). The rear shock absorber works in conjunction with a generously sized but lightweight double sided swingarm (in aluminium on the Racing model and steel on the X-Treme), which complements the agility of the superb chassis layout.
Both the X-Treme and Racing come with oversized brake systems: with a 260 mm disc at the front and a 220 mm disc at the rear for maximum safety in all situations.
The R and SM versions of both the X-Treme and Racing differ in the wheels fitted. While the R enduro model is equipped with a 21” front wheel and an 18” rear wheel shod with off-road rubber, the SM supermotard runs on 17” street wheels at the front and rear fitted with street tyres.
Both models are powered by a scintillating liquid cooled 50 cc 2 stroke engine giving the DRD X-Treme and Racing class beating performance, with maximum torque already available at low engine speeds. Compliant with current emissions regulations (Euro2), the 50 cc 2 stroke units make the new Senda models fun to ride with gusto and give them genuine pro performance. A lightweight, reliable engine in a fun, agile and versatile bike.
