Ducati Brisbane ST3

Ducati ST3

The ST3 is the ideal solution for the demanding tourer who, instead of being content with the classic "German style" of touring, needs the typical verve of an Italian machine.

In addition to the high level of protection, careful attention devoted to ergonomics and the sophisticated chassis set-up, riders can rely on an engine that has been specifically designed to produce very specific power characteristics. The design solution of Desmodromic control with three valves per cylinder and dual spark ignition has enable an impressive level of performance while maintaining low fuel consumption. All these benefits are achieved in full while also complying to Euro 3 homologation.

Style

One aspect of design that the ST engineers worked hard to reconcile was related to the management of overall dimensions. In this area, it was important to offer adequate protection for the rider and passenger, while taking care to maintain the slender profile of the machine and avoiding any reduction of the model's sports capabilities. The solution was with a carefully calibrated blend of elegant lines and functional features designed also to meet strict aerodynamic requirements. The ST3 is therefore the perfect long-distance machine for all touring situations, but also suitable for normal day to day use.

Chassis

The ST3 was born to travel, but the design project was conducted with a constant eye on the sports performance. Consequently, one of the defining features of Ducati's DNA has been retained in the form of the high strength tubular steel Trellis frame, as used on all the models including the Desmosedici MotoGP bike. The steel Trellis frame is an area in which Ducati has acquired an enviable level of experience.

Reduced weight and a high level of torsional stiffness are just a few characteristics that bring clear benefits to both solo riding at high speed and long trips with a passenger and a full luggage load.

Of course, the Ducati Sporttouring machine makes it easy to find the perfect set-up for all trips thanks to the use of highly versatile front and rear suspension. The front end is equipped with Showa forks with adjustable preload, while the rear has a Sachs single shock with full preload and damping adjustments.

Powerplant

The Desmo3 powerplant is the product of the very latest engineering techniques and offers an intermediate solution between the classic air-cooled two-valve and the more sports oriented four-valve engines. With its three valves per cylinder the engine manages to condense the qualities of the other engines as well as maintain low fuel consumption and flexibility.

The ST3 was one of the first production machines to offer lower exhaust emission levels. This goal was achieved thanks to the adoption of an integrated ignition, injection and exhaust system with a special three-way catalytic converter and heated Lambda oxygen sensor.

Another important breakthrough is constituted by the addition of automatic idle speed control provided by a stepper motor. The benefits of the three-valve cylinder head, which features the traditional Ducati Desmodromic control, include plenty of torque at low engine speeds and fuel consumption that is among the lowest in the category (typical of 2-valve engines) combined with high power throughout the rev-range (typical of 4-valve engines). In this context it should be noted that numerous components were designed specifically with the aim of extending the interval between servicing times.

As in the case of the specifically designed wet clutch, which, apart from featuring quieter operation, offers exceptional resistance to wear to provide an estimated lifetime in excess of 100,000 kilometres.
