Abstract:
To provide an aluminum wheel for a motorcycle in which productivity can be improved while ensuring sufficient strength, lightweight properties, and toughness. The rim diameter is 14-17 inches. Ten spokes (151) are provided. When the smallest of the cross-section areas of cross-sections orthogonal to a direction (D1) of extension of a spoke (151) (e.g., line A-A cross-section) is deemed to be a minimum spoke cross-section area, the total sum of the minimum spoke cross-section areas of the ten spokes (151) is 8 cm2 to 15 cm2. Heat processing is performed after casting by die casting.
