1977 BMW R100RS Project

Okay, I’ve yet to achieve the first of the 12 steps for recovery: Admitting You Are Powerless Over Your Addiction. I see no problem in adding one more bike to “Brook’s Garage” inventory of BMW Airhead projects. So, I’ve acquired a 1977 BMW R100RS with about 37,300 miles. Yes, I already have the 1983 R100RS bike project, but 1977 is the first year for this innovative machine from BMW.  So, getting one has been on my “Lust List” for awhile.  Now, it’s in the last remaining storage space next to my car in our garage.

[Hey, maybe if I just sell the car I get 1/2 a garage for more bikes!!! But, I think that way lies divorce, so an even half dozen Beemer Bikes is the limit for “Brook’s Garage”.]

My intent is to complete a frame-up restoration of the bike, but when I start that, I haven’t decided yet. Right now I just began assembling the 1975 R75/6 “S” project bike and the 1983 R100RS was next in line; but that was before the 1977 came home.  I’ll see what grabs me when I get the R75/6 “S” out of the shop.

The bike is a “10 foot bike”: It looks nice from 10 feet away :-):

I’ve ridden it about 75 miles and it certainly shows the value of the 40 mm Bing carburetors and lack of EPA mandated emissions modifications compared to the 1983 R100RS.  It has dual plug heads, oil pressure and oil temperature senders and VDO gauges (not installed at present, so I’m not sure the gauges or senders still work), heated grips and is claimed to have the reinforced snowflake wheel installed.

The cosmetics need attention, and we shall see what surprises are inside in due course. Someone did invest in it at one time as evidenced by the modifications, but there are also signs of being parked and ignored as well.

Here is a slide show of some close-up photos:
