Looking for high-quality Yamaha XS1100 parts? This collection includes OEM and aftermarket replacement parts for all Yamaha XS1100 models, produced between 1978 and 1981. Whether you’re restoring a factory-correct standard or maintaining one of Yamaha’s most durable big-bore motorcycles, this collection provides the essential components needed to keep your XS1100 on the road.

Introduced in 1978, the Yamaha XS1100 was Yamaha’s answer to the liter-class superbike wars of the late 1970s. Powered by a 1101cc air-cooled inline-four engine with double overhead camshafts, the XS1100 delivered massive torque, smooth power delivery, and exceptional reliability. Rather than chasing peak horsepower numbers, Yamaha focused on real-world performance, durability, and long-distance capability.

The XS1100 was offered in multiple configurations, including Standard, Special, and Midnight Special variants, all sharing the same core engine and shaft-drive drivetrain. Known for its stability, strong acceleration, and ability to cover serious miles, the XS1100 quickly earned a reputation as one of the toughest and most dependable large-displacement motorcycles of its era. Today, it remains a favorite among vintage touring riders and restorers alike.
