Wheel for Motorcycle
DRIVE
August 14, 2013
In a wheel for a motorcycle which is formed by casting as an integral body formed of a hub portion which is supported on an axle, a rim portion which coaxially surrounds the hub portion with a tire mounted thereon, and a plurality of spoke portions which connect the hub portion and the rim portion, the reduction of weight can be realized, and also the reduction of man-hours of a sand removing operation can be realized. A spoke portion (35) includes a spoke proximal portion (35a) which extends radially from a hub portion (33) and a pair of spoke branch portions (35b) which is bifurcated from a distal end portion of the spoke proximal portion (35a) and is contiguously formed with the rim portion (34), and a continuous hollow portion (48) is formed in the spoke proximal portion (35a) and the hub portion (33).
