2006 Ducati Monster 620, 620 Dark
Once again it's the job of the Monster 620 machines to provide the entry level to the Ducati range of naked bikes. All equipped with the less intimidating twin cylinder 629cc engine with APTC clutch (the slipper clutch developed by the Borgo Panigale engineering team to provide a lighter lever pull and prevent rear chatter during hard deceleration), the 2006 comes in two versions: the 620 Dark, with twin front discs, and the 620 classic, in two colour versions.
Ducati red and black are the chosen colours for the 2006 Monster 620, together with the handsome matt black finish of the Dark version. On the red and black versions, the former features a red frame and black wheels (recalling the Desmosedici bike that prevailed in the MotoGP world championship), while the latter has a black frame and black wheels reminiscent of the Monster S4R. The Dark version is characterised by the absence of the removable seat cover, which adds aesthetic appeal to the seat when riding solo, and the absence of the front fairing and rubber clad footrests. On Monster 620 models the paintwork on the seat cover is identical to that of the mudguard, tank, and front fairing.
The suspension equipment consists of fork and rear monoshock, complete with a brake system with two 300 mm discs on the front wheel, able to reassure riders who insist on the maximum safety and making the task of controlling the impressive stopping power of the system more manageable. This equipment is completed by a Marzocchi upside-down fork with 43 mm stanchions, and a Sachs shock with adjustable rebound and preload, plus a Brembo rear brake with 245 mm disc and fixed calliper with 2 opposing pistons.
The six-speed gearbox and electronic fuel injection control system maximise the pleasure in controlling the impressive power output of the air-cooled twin engine installed on Monster 620 models. Performance levels are impeccable, and riders can rely on a smooth torque delivery in all riding conditions, starting from high-traffic city routes. This engine is also able to deliver a potent torque curve, a quality that enhances the ability of Monster machines to offer extreme ease of handling and agility in mixed riding conditions. Like its predecessors, the 2006 model features the Adler Power Torque Plate Clutch (APTC) developed in accordance with the Ducati R&D department and equipped with a torque feedback control system. This means that the relationship between applied torque and transmitted torque is always linear, resulting, among other things, in a reduction of pulling force required on the handlebar lever. Another important characteristic of the APTC system is its ability to provide automatic limitation of reverse torque during sharp deceleration, thus eliminating potentially dangerous rear wheel chatter effects. The third and final benefit, although certainly not of negligible significance, is the fact that the evolution did not call for any form of modification to the clutch housing and the structure of the primary transmission.
