After a 20-year break since the R100/S, BMW's re-entrance to the more sporting side was thoughtfully considered, with lots of new engineering, and as they approach classic status, a great success. This nicely-updated R1100S looks excellent and fans of the brand would say, just broken in with 22,000 miles.
The R1100S arrived with concepts new to sportbikes - the four-valve 1085cc boxer, Telelever front and Paralever rear suspension with shaft drive, single-plate clutch, ABS, and some things newer to BMW - clip-on handlebars and underseat exhaust. BMW kept their vaunted build quality and usual Bosch fuel injection, but tried to leave the weight behind. The engine is a stressed member of the aluminum chassis, and the supersport fairing flows from the beak, over the tank to the pillion cover. Great power at 98 hp with 72 ft.-lbs. torque, and with a dry weight of 505 lbs. it's light for a BMW.
Offered by an Illinois dealer, this R1100S looks well taken care of and has the optional grey / orange checkerboard. A more sporting build since the ABS, centerstand, and heated grips were left off. The owner has upgraded to Ohlins dampers on both ends, and added conspicuity lights on the fork legs. The bags look like they just came out of the closet where, handy as they are, they should be returned. From the eBay auction:
This 2004 BMW R1100S has only 22,370 miles and has had all of its maintenance performed by Cycle Werks in Barrington, we are an authorized BMW dealer. This bike comes with BMW Saddle Bags, Ohlins suspension, Aux. Driving Lights, and much more!
For a BMW it's sporty, light, and this one with low miles, and though succeeded by the R1200S, the R1100S is regarded as the better track machine. The bike was the source of many years of the Boxer Cup, a single marque support series, resulting in the special edition Boxer Cup Replica. But you can find an R1100S at almost any track day or racing school, just look for the guy with no trailer, he'll be riding it home...
