The 1981 Yamaha XS 1100 S represents a significant entry in the early 80s superbike landscape, a powerful evolution within Yamaha's XS series. This particular "S" variant, often referred to as the "Special," offered a more touring-oriented take on the standard XS1100, competing directly with contemporaries like the Honda CBX and Kawasaki KZ1300 for big-bore supremacy. It aimed to provide a comfortable yet potent grand touring experience, building on the reputation of its predecessors while pushing the boundaries of four-cylinder performance.

At its heart, the 1981 XS 1100 S boasts a robust 1101.00 ccm (67.18 cubic inches) in-line four, four-stroke engine. This impressive powerplant generates a substantial 95.00 HP (69.3 kW) at 8000 RPM, propelling the machine to a top speed of 217.0 km/h (134.8 mph). Fuel capacity stands at a generous 24.00 litres (6.34 gallons), allowing for extended journeys without frequent stops. This ample power output and fuel range solidified its position as a serious contender in the Vintage category, offering substantial power for its era.

Riding characteristics of the XS 1100 S leaned towards comfort and stability, aligning with its touring aspirations. While not a lightweight, its long wheelbase and shaft drive contributed to a smooth and predictable ride. The "S" model typically featured higher handlebars and a stepped seat, promoting a more upright stance compared to sportier alternatives. This ergonomic setup, combined with adequate suspension, made it suitable for long-distance cruising, absorbing road imperfections with reasonable composure. The bike's overall feel was one of planted confidence rather than agile flickability.

The 1981 Yamaha XS 1100 S was primarily targeted at riders seeking a powerful, reliable, and comfortable touring machine, especially those who appreciated the smooth power delivery of an in-line four engine. It appealed to individuals looking for a grand tourer capable of covering significant distances with ease, rather than track-focused performance. Its Vintage status today makes it a desirable classic for enthusiasts appreciating its engineering and historical significance as a formidable early superbike.
