It will be appreciated that in order to enable the rim to be extruded on a metal extrusion process, any radial cross-sectional profile of the rim is substantially uniform irrespective of the additional structure formed on the rim by subsequent hole making or the like processes of the extrusion process.
The spoke motorcycle wheel is described below in two specific embodiments.
Example one
Referring to fig. 1 to 5, the present embodiment provides a spoked motorcycle wheel comprising a rim 1 and a hub 2, the rim 1 being fastened to the hub 2 by a plurality of individual spokes 3. The rim 1 comprises an inner rim 11 and an outer rim 12 which are formed into a whole, and in order to facilitate the rim 1 of the spoke type motorcycle wheel to be obtained by extrusion through a metal extrusion forming process, the inner rim 11 and the outer rim 12 are in a regular annular structure with any radial section pattern consistent.
