    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.

    Building a Custom XS1100?

    Some parts on a custom build are not model-specific. If you’re changing handlebars, mirrors, lighting, controls, shocks, exhaust pieces, fuel line, or hardware, visit our universal and custom motorcycle parts collection.

    These parts are useful for cafe racers, brat builds, trackers, choppers, and garage-built vintage motorcycles, but they are not guaranteed to fit every bike without checking. Always compare measurements, mounting style, clearance, and product notes before ordering.


    Yamaha XS1100 parts questions

    What model years does this Yamaha XS1100 parts collection cover?
    This collection covers Yamaha XS1100 models from 1978 to 1981. Because specifications changed across that span, check your year, model code, and any prior repairs against each product's listed application before ordering.
    What kinds of Yamaha XS1100 parts are in this collection?
    You will find carburetor and fuel-system parts, engine gaskets and seals, brake components, and control cables and levers. Availability shifts as stock moves, so the live product grid above is the accurate list at any given moment.
    Are these Yamaha XS1100 parts OEM or aftermarket?
    Both. Old Bike Barn stocks genuine OEM replacements alongside quality aftermarket parts, and each listing states which it is. OEM suits a period-correct restoration; aftermarket often costs less or offers an upgrade over the original design.
    How do I confirm a part fits my Yamaha XS1100?
    Check the application details on the product page against your year, model code, and engine or frame number. Older machines are often not original, so confirm the part you are replacing rather than assuming factory spec. If you are unsure, contact us before ordering.
