Here is a NOS Gen-U-Wine Z1 grip, now you will notice how the individual grippy bits are domed (have a radius) ....

So I ordered the matching version from a seller in the US, and today this arrived.....


As you can see the little grippy bits are flat, so what bike was this made for? it is not the same as the part that was advertised by the seller, as their ebay picture had the domed grip?
