1979
The 1979 Yamaha XS 1100 arrived on the scene as a formidable contender in the burgeoning superbike class, building on Yamaha's reputation for powerful, multi-cylinder machines. Following the success of earlier XS models, the XS 1100 was positioned to challenge established giants like the Honda CBX and the Kawasaki Z1R, offering a compelling alternative for riders seeking robust power and a substantial presence. Its classic UJM (Universal Japanese Motorcycle) styling, characterized by a large fuel tank and a prominent engine, resonated with the era's aesthetic preferences.
At its heart, the XS 1100 boasted an 1101.0 ccm (67.18 cubic inches) in-line four, four-stroke engine. This powerhouse delivered 95.0 HP (69.3 kW) at 8500 RPM, coupled with a solid 66.0 Nm (6.7 kgf-m or 48.7 ft.lbs) of torque peaking at 6500 RPM. These figures translated into a top speed of 215.0 km/h (133.6 mph), making it a seriously fast machine for its time. Weighing in at 258.0 kg (568.8 pounds), the XS 1100 was a substantial motorcycle, and its 24.00 litres (6.34 US gallons) fuel tank ensured a decent range for longer journeys.
Despite its significant weight and powerful engine, the XS 1100 offered a surprisingly manageable ride. The 810 mm (31.9 inches) seat height, if adjustable to its lowest setting, provided decent accessibility for a wide range of riders. Its upright stance, typical of UJM designs, offered a comfortable cruising position, making it suitable for longer excursions. While not a track-focused machine, its shaft drive system provided smooth power delivery and reduced maintenance compared to chain-driven counterparts, contributing to a refined riding experience.
The Yamaha XS 1100 was designed for riders who valued power, reliability, and a comfortable, stable platform for covering serious distances. It appealed to those who appreciated the straightforward engineering of the era and desired a motorcycle that could effortlessly eat up miles. For the enthusiast seeking a classic superbike with a strong engine and a commanding presence, the 1979 XS 1100 remains a compelling choice, representing a significant chapter in Yamaha's performance motorcycle history.
