great bike it is worth every dollar you put into it.it has always been my understanding that the 88 is the exact same bike as the 87 except for the color.im pretty sure the 88 rim is the same except for the color thus it has a diff. part number.you can have your parts guy contact honda directly to check or have him check the part number for the hub it should be the same i dont think they changed the color of the hub.you might want to check after market rims, you may get a better rim for less or equal money and you can get it in gold so it will match.a good wheel shop should be able to take care of you no problem, you can even up grade your spokes and nipples at the same time if you like.contact bucannons wheel shop in montery park cal. they do my wheel work and have even mounted rims for me that dont quiet match it might be worth your time to have them take care of you
