The 1999 BMW R 1100 S

1999 BMW R 1100 S launched as the sportiest expression of BMW's Boxer platform, sitting below the R1100RT tourer in the family but bringing a sharper edge than the R1100RS it was gradually replacing in that role. This is a bike built for riders who want long-distance capability without giving up cornering feel — the Telelever front end tames dive under braking, and the shaft drive means you're not fussing with chain maintenance between trips. It rewards a confident, committed riding style more than a lazy highway cruise, though it'll do that too. The seating position leans forward enough to remind you this isn't a pure tourer, but the fairing and tank range keep it livable on longer hauls.

The 1999 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 1998 example should focus on mileage, service history, and condition rather than spec differences.

Owners tend to be experienced riders moving on from sport bikes who want comparable performance with less physical punishment, or BMW loyalists upgrading from an earlier Boxer. Collector interest remains moderate, with well-maintained examples holding steady appeal.
