Its balance of performance and simplicity made it popular with new riders, commuters, and experienced motorcyclists alike.
Throughout its production run, the XS400 was offered in several configurations, including standard and cruiser-style variants, all sharing the same core engine architecture.

Building a Custom XS400?
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.
