1977 BMW R100RS/RT For Sale - $4500

From the ad, "In its original paint, a 1977 R100 with the RS suspension and RT fairing and BMW saddlebags. Either factory done or very professionally done conversion. Professionally done dual plug cylinders with an electronic ignition and Mikuni flat slide carburetors." Love the color but definitely a rider not collectible. Note the snowflake rear wheel vs mono airhead front wheel. Love the color on this one so had to repost it. For sale in Austin on Craigslist.
