Abstract
A motorcycle wheel includes a rim portion, a hub portion, a joining portion extending between the hub portion and the rim portion, and an axle housing portion. The joining portion includes first and second sidewalls defining outwardly-facing continuous concave surfaces. The first and second sidewalls define a well adjacent the rim portion. The first and second sidewalls contact each other at a merger portion intermediate the hub portion and the rim portion. The first sidewall is slightly thicker than said second sidewall to facilitate casting the wheel as one piece. A merger point in the merger portion has a thickness that is less than the minimum thicknesses of a portion of the first and second walls between the hub portion and the merger portion. The hub portion includes apertures to reduce the weight of the wheel. The axle housing portion protects a motorcycle axle from debris passing through the apertures in the hub portion, and stiffens the axle bearing supports.
