2005 ST4s & ST4s ABS

The ST4S bristles with our best race-derived components combined with all-day riding comfort. Start with the awesome Superbike 996 cc Desmoquattro engine, liquid-cooling, computer-controlled fuel-injection, 11,5:1 compression, 50 mm throttle bodies and a six-speed transmission. Include the latest Showa forks, exclusive Öhlins rear shock and CAN line electronics. The result is a bike that excels on the street and the racetrack.

The ST4S offers fully-adjustable Showa upside-down 43 mm forks with TiN treatment, as seen on the most exotic race bikes, lowering suspension friction to ensure accurate and responsive action.
And for quick "situation tuning", the Öhlins rear shock features a remote spring pre-load adjustment system that allows you to easily adapt the rear spring to load weight. So whether riding solo or two-up with saddlebags full or empty, you are promised a smooth ride.

The new, evolved ABS system is the jewel in the crown of this model. At the core of the Ducati ABS system is an advanced electronic processor that senses wheel slip and assists in preventing tire lock-up in emergency and low traction situations. The Ducati ABS system has been tuned for more aggressive riding to compliment the performance capabilities of the ST4S. The system can be switched-off when the rider elects to explore the performance of non-ABS braking.
