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.

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.

Here's mine.


I have two original sets of wheels for my '77RS.
They are both painted matte silver with blue pinstripes.


You might take a closer look at yours.

I don't believe they were anodized since the tube side of the rim doesn't show anodizing and isn't painted either. I don't know if it's possible to anodize the 'outer' surface of the rim and not the 'inner', but think not.

It's possible the rim was etched to help the paint adhere, or at least prepped in some way because bare paint wouldn't have stuck as well as this. I haven't seen evidence of primer, and normally zinc chromate (yellow) is used for that. Maybe they got blasted with a fine powder to rough them up, I don't know. But however it was done they certainly did a good job.

OK here's another question on the paint was the fairing only a matte finish and the tank and tail section a clear coat I ask this because the web site that Jon-Lars posted that bike's tank and tail section is clear coated and only the fairing is matte there's a couple of angles that look like the front fender is cleared also????

[bmweuro]

They were painted with a base coat paint(made for a clear coat) and no clear.

[Jon-Lars]

Matte all over. It's a difficult finish to maintain.
