A lightweight composite motorcycle wheel construction characterized in that it comprises a wheel unit casting including concentric outer and inner rim and sleeve portions integrally connected together by angularly spaced spokes; and a hub unit casting having an interference fit within the bore of the sleeve portion thus to frictionally retain the hub and wheel units together against relative angular and axial movement while the bearing receiving bore in the hub unit is located and held coaxially of said rim portion, the wheel and hub units additionally being welded together to prevent relative angular and axial movement despite application of torque and axial loads exceeding the frictional resistance of the interference fit.
