BMW R 1100 S R11S spare parts

BMW R 1100 S R11S spare parts - the sports tourer that redefined the boxer concept

As BMW in 1999 R 1100 S sent into series production, it received the internal series code R11S. After the small pre-series R2S, the production model adopted the 1085 cc Oilhead, but gave it the more robust M97 gearbox, a new Motronic MA 2.4 and optional ABS-II brakes. Between 1999 and 2005, several equipment variants were created - including the legendary one Boxer Cup Replica. In order for the sports tourer to still exploit its potential today, it needs precisely fitting ones BMW R 1100 S R11S spare parts. This overview explains what is important.

Oilhead base – engine, chassis & electronics

98 hp at 7,500 rpm, 97 Nm at 5,750 rpm - key data that ensure the R11S boxer has a respectable performance plateau even two decades later. The mix of Telelever front and Paralever rear swingarm combines precise steering with the low maintenance typical of gimbals. For maintenance and possible upgrades, the spare parts portfolio is divided into four core areas:

Model updates 1999 – 2005 – what has changed?

• ✓ 2001: M97 gearbox receives reinforced bearings, clutch push rod with NBR sealing ring.
• ✓ 2003: Dual ignition (two candles/cylinder) to prevent ringing and exhaust pollutants; new alternator 600 W.
• ✓ 2004: Boxercup Replica II - steering damper, carbon belly pan, Akrapovič system (E number), driver's seat +20 mm, blue/white paint.

When replacing parts, it is therefore important to note the year of manufacture and VIN code (numbers 7-11) - e.g. B. Spark plug connector: single stick coil until 2002, double stick from 2003.

Typical weak points & preventive spare parts

Tuning potential – sportier without compromise

Spare parts supply – OEM, aftermarket & community

Thanks to its heritage policy, BMW continues to supply many R11S parts new: e.g. E.g. frame parts (41-…-…), engine seals (11-…), ABS hydraulics (34-…). Renowned aftermarket brands (TRW, EBC, Siebenrock, Touratech) cover brakes, chassis and carbon fairing. In forums like powerboxer.de or boxercup.de Fans exchange knowledge and stocks so that even unusual components (yellow speedometer dials, BCR carbon parts) can still be found.

R11S & R2S – Parts Compatibility

Around 90% of the R2S spare parts fit the R11S - drivetrain, brakes, fairing. The following are not compatible: M93 gearbox, MA 2.2 Motronic unit, yellow scaled cockpit, ABS sensor ring bolt circle. When ordering online, compare the VIN or part number.

Performance & Boxer Cup Bonus

Standard R11S are priced below 1200S, but well-maintained dual ignition models and Boxer Cup Replicas are gaining popularity. Proof of regular oil and valve service, documented BMW spare parts and untampered panels are the main factors for increased value.
