Pair of Motorsport BMW

It is interesting to see how two sellers with the same motorcycle describe what they have on offer. Here is a case were two sellers of two 1978 BMW Motorsport Edition R100RS describe their bikes.


From the seller of this 1978 R100RS

1978 BMW R100rs in original condition w/7128 miles. This is a Motorsport Edition in “police white” w/”rennsport red” fairing & blue/blue/red pinstriping. This is a Texas titled motorcycle and has been kept in a climate controlled environment for most of it’s life. It has a new Yuasa battery & fresh rubber. This bike also has matching white panniers & a “dual” seat to go with the solo saddle. I have all manuals that were issued w/the bike and the original BMW tool kit. The solo seat pan has a small crack in the fibreglass as shown in photo and the right battery cover has a small stain at the upper right corner. A tiny chip in the rear of the solo seat cowling can also be seen in the video. This bike would make a nice example for a collector as it has very low miles and runs

…For those who know or care this is 1 of 200 CFO bikes produced by BMW in 1978.  40mm carburetors & 40mm exhaust.

From the second seller of this 1978 R100RS

Being offered here is my 1978 R100RS Motorsport, the bike I thought I would never sell. I bought this bike from a gentleman that had prepared the bike mechanically for a cross country trip that never happened. I have since done a frame off restoration on this beauty over the passed three years. Here is a list of work done.

Professional repaint using the correct Glasurit paint colors for this model. The original hand pinstripes were left intact,taped over for paint, then a clear coat was applied.

Frame was sandblasted and powder coated black. New oem rear grabrail.

All the nuts and bolts on the frame are stainless steel.

New complete exhaust system.

The seat is a new stock reproduction.

The speedometer and odometer have been rebuilt and set to the original mileage.

The clock and volt meter both function as do all lights and turn signals,even the turn signal warning buzzer works.

A new sealed battery installed last year.

Stainless steel front brake lines, calipers and master cylinder rebuilt.

Rear master inspected and cleaned  as well.

Lightened flywheel and new clutch.

Carbs rebuilt, including new floats.

I have new BMW handgrips on the bars.

Also included with the bike is the original tool kit, air pump, and cable lock.

I have a set of K75S handlebars and new BMW handgrips to go with the bike if the buyer wants them.

New Metzler Lasertec front tire this season, ear Lasertec has around 1500 miles on it.

Now for the disclosure. he previous owner had the carb tops chromed and started a dual plug conversion but never finished. he paint has worn off the edge of the voltmeter and the windscreen has some deeps scratches in one corner. There are a couple of small chips in the side covers. You can see this in the pictures.

The bike runs and rides beautifully. The mileage stated may change as I still ride the bike.

The R100RS was the top of the line for BMW, and the Motorsport RS is a special edition of a special bike. The R100RS was new to 1977, and when they first rolled into the hands of riders, they came with 40mm Bings and 40mm Exhaust taps. Soon afterwards the exhaust was reduced to 38mm and given more restrictive mufflers. These bikes were stamped “CFO” and this was to certify that they would pass California, Florida and Oregon emissions requirements. So I am wondering about the first sellers apparent conflicting statements about the bike. R100CS, CFO and 40mm/40mm.

I am sure that there are people who have been able to unravel the nature of these special editions. The R100RS Motorsport Edition was limited to 200 bikes and only offered in 1978. The seller of the second bike gives the vin number, and I found a vin decoder which shows it was manufactures as a R100RS on 1977/10 which would end up on the dealership floors for 1978. The seller of the “R100CS” Motorsport does not include a Vin number. The Motorsport Edition appears to have been a “Badge” edition with only special paint to distinguishes it from the others RS’s. But again, there is a lot of information that I could not find, so do your homework when getting special editions of special bikes. It is nice that you have two to choose from, but hurry there has been active bidding, and one is ending soon. BB
