The 2004 BMW R 1100 S
2004 BMW R 1100 S sits toward the sporting end of BMW's boxer-powered lineup, built for riders who want speed and long-distance comfort without stepping into a full-race crouch. This is a bike that rewards confident, quick-handed riding on twisting back roads while still being civilized enough for a highway blast to the coast. The Telelever front suspension gives it a planted, unusual feel under braking compared to a conventional fork, and the shaft drive means you're not fussing with chain maintenance between rides. It's a bike that asks you to adapt to its boxer character rather than the other way around, and owners who get along with that layout tend to stay loyal to it for years. The 2004 model carried over without significant mechanical changes from the prior year, so buyers comparing it to a 2003 example should focus on mileage, service history, and condition rather than spec differences. This generation appeals to riders coming off standard nakeds or older sportbikes who want distinctive engineering and shaft-drive practicality without chasing outright track performance. Collector interest remains moderate, drawing BMW loyalists and buyers who appreciate the boxer sport-touring format before it gave way to more mainstream superbike styling.
