    Any disc brake /6/7, spoked or snoflake, will fit right up.

    You'll never find the exact 'blue striped' one ... but a /6 or /7 spoked wheel can be had all day long on fleabay. IMO, buy a cheap straight one ... and when you get it, immediately swap out the bearings. Should last you a lifetime.

    Don't forget if you do find a set of Blue Pinstripe wheels to also get the Blue Anodized Ate calipers. :D

    And BTW I think these parts were 1978, not 1977. I was informed of this less than a month ago when I said the same thing.

    The '78's came with snowflakes. The '77's had the blue pin-striping on the rims, and the blue ATE's. I'm pretty sure of it.

    77 rear wasn't a drum brake on the RS? It is on my S

    edit: Just looked at some photos and the rear is in fact a drum on the 77

    Yeah, I was speaking the front. The rear will work for any drum /6/7.

    And I was a bit wrong on the front. Any /6 75-76 will do. The 74 had a smaller axle.

    And right you are. The '77 RS spoke wheels should have blue pinstripes.

    The rims themselves are painted silver, not polished aluminum, then striped in blue the same shade as the bodywork pinstripes.
    You can find sets of wheels for sale once in awhile. Lots of people removed them in the rush for fashionable cast wheels from BMW, Lester, and Morris. I have a spare set myself for my '77RS.

    That's correct - the BMW wire wheels are interchangeable. But the early /5 rear rim was narrower and the /5 rear hubs are a little different. Of course the 1970-74 fronts won't work either.

    And the rims are painted a dull silver with the blue pinstripes. Really cool looking but I'm hesitant to ding them up or rub them too much while cleaning.

    so were the 77's rims aluminum painted dull silver or steel painted dull silver?

    They were an anodized aluminum wheel which helped keep the aluminum from oxidizing which helped the paint last for many years. Then them rims where painted and pinstriped.

    If your rims are polished aluminum with blue pinstripes, they have been modified.

    Is your bodywork paint matte finish, or is it shiny?

    Not polished at all, when did I say polished? Matt Aluminium with pinstripes, not refinished, as standard, Matt Blue Paintwork, I don't have to refer to a website, I just walk into my Garage to see the original.

    The rims were anodized first so it would not have a polished look but more of a dull finish. I think I have also seen them as Bulldust has on his bike. What month was your bike built in?

    Built February 1977 (6180710).

    These bikes were designed originally to have snowflake mag wheels, a production fault/delay caused the first year to be sold with spoke wheels, having regard to BMW's practice of using what parts are to hand (some of the last R90S's to come to Australia had 1,000 cc barrels and /7 wiring looms) it is possible that the earlier production of the 77 model had a different wheel finish to bikes built later that year. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>

    Most new models start in August of the previous year however the 77 RS started in June of '76 so that would make yours a mid model year build for what ever that's worth.
