Overview

Introducing the 1999 Ducati ST4, a remarkable motorcycle that embodies the heart and soul of sport touring. Designed for riders who crave the thrill of the open road while demanding comfort and versatility, the ST4 seamlessly blends performance with practicality. As part of Ducati's storied lineage, this motorcycle stands out with its distinctive Italian flair, combining sleek aesthetics with the cutting-edge technology that Ducati is renowned for. With a focus on both touring capabilities and sport performance, the ST4 has carved out a niche for riders who appreciate the balance between spirited rides and long-distance journeys. At the heart of the ST4 is its powerful 916cc V2, four-stroke engine that generates an impressive 105 horsepower at 8,500 RPM, delivering exhilarating acceleration and a top speed of 151 mph. The engine’s torque of 83 Nm at 6,500 RPM ensures robust mid-range performance, making it an excellent companion for both spirited highway cruising and twisty back roads. The ST4's 6-speed transmission offers smooth gear changes, enhancing the overall riding experience while the liquid cooling system maintains optimal engine temperatures. With a remarkable fuel efficiency of 0.59 liters per 100 kilometers, this bike allows riders to traverse greater distances without the frequent need for fuel stops, making it an ideal choice for long tours. The ST4 is not just about raw power; it is packed with features that enhance both comfort and performance. The chassis combines a lightweight frame with a well-balanced suspension system, offering 130 mm of front travel and 148 mm at the rear, which allows for confident handling and stability in various road conditions. The braking system features dual front discs and a single rear disc, providing reliable stopping power when needed. With an adjustable seat height of 820 mm, the ST4 accommodates a variety of rider sizes, ensuring comfort during those long journeys. Add in Ducati's signature electric starter, and you have a motorcycle that is as convenient as it is thrilling. **
