Building a Custom YZ125?
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.
