Came across a 78 R100RS in factory Motorsport colors (white, red/blue stripes) and equipped with an S fairing, which the owner says is original. What say the experts?

Assuming it's original, that

Assuming it's original, that would be a rare R100SRS.

S fairing on RS

It's S/N shows it's an RS, but why would BMW put an S fairing on when that is the only only difference between an S and a RS. Makes no sense?

I kept some notes from Tom

I kept some notes from Tom Cutter who worked at Butler and Smith during this time. He said that about 90 R100S models were made because BMW had a specific number of emissions certificates that were authorized and they had more VINs in that range than bikes that were imported, so they started "using them up" and back dating production labels in order to meet the January 1, 1978 EPA cutoff date. The book by Andy Schwietzer also mentions the livery for the R100S and that some were delivered in a multi-blue and on a silver base paint scheme. He says they were marketed as the "Air-Line" models...whatever that means.

SRS - Airline

Indeed - the story as I heard it was that in 1978 the Australian Police cancelled an order for RS bikes fitted with S type fairings. These bikes then got sprayed up as Motorsports and sold on to the general public as "SRS".

The Airline "Exclusive Sport" model is a different thing entirely. Advertised as a special edition and featuring polished carb tops, fork legs, rocker covers and bevel box, these were in reality just the last of the old heavy flywheel ATE equipped bikes that nobody wanted. They got sprayed silver and a special set of vinyl stickers got put on tank, seat and fairing, and a few hardy souls bought these instead of the lighter flywheel Brembo equipped R100CS bikes that were, in fact, much better value.

Certainly here in the UK neither bike would attract much of a premium, despite what their owners might hope for. BMW twinshock "special editions" rarely seem to be more than a paintjob.

My Bike

I have had one of the late '78 R100S Motorsports for quite a few years now as my daily rider. My understanding was that some of the original 200 USA sold Motorsport R100S' were outfitted with S fairings.

Supposedly there were then an extra ~25 at the very end of the 1978 model year sold in the USA. Mine reputedly falls into that group. I had references at one time that stated these were actually uncrated by Tom Cutter when he was at B&S. I lost all that in a hard drive crash. There are some slight cosmetic differences between the early ones and the later. Although I have seen variations in the first 200. This seems like a bike that there are a lot more now than what were made. People, I guess, thought that they would become very collectable. The problem is the factory cannot absolutely confirm that it is one, only that it falls within the range. The range is much larger than the amount that were Motorsports.

Mine was made in June 1978 and has a European serial number.

I personally don't consider them any more collectible than any other 1978 R100S and use it as a rider to be enjoyed. I bought it because of the color scheme that I found attractive. It has the larger valves and higher horsepower. disc in the back (sucks vs drum) and the blue seat (which I don't use) and the very tall gearing for the rear drive. Don't get me wrong, I love the bike dearly and I will be with me until I pass.

Hey fellow Airheads, Last

Hey fellow Airheads,

Last July I purchased a 1977 R100RS with S fairing and it was parked in garage for many years.
So I wanted to know a little more about these R100SRS model people seem to be very little info out there.
Can anyone tell me serial number range of Australian Police?
I heard they were made and at the last minute the order were cancelled. 500 units were completed and 50 were imported to the US market by
Bulter and Smilth.

I've found a picture from a UK website that has plate but does the US version have one too?

You can visit our model page

You can visit our model page for the R100RS, which lists all of the serial numbers and indicates which were US vs. rest of world. The only way to know the specific history of your bike is to send the serial numbers to BMW Group Classic for them to look up in their records: info.grouparchiv@bmwgroup.com.

The pictures you've posted

The pictures you've posted aren't all of the same bike; which one is yours? The Motorsport paint scheme was a '78 model year treatment, and '78 S and RS models had rear disk brakes and snowflakes. If yours is the '77 pictured with the spoked wheels and rear drum, a PO has had it repainted in the Motorsport paint scheme---it didn't come from the factory like that.
