BMW R 1200 GS “Hexhead” (2004-2009) Maintenance Schedule and Service Intervals

Fully loaded 2006 BMW R 1200 GS Adventure

This is the maintenance schedule and service intervals for the very first generation of BMW R 1200 GS, released in 2004 and made up to the 2009 model year. It also includes the maintenance schedule for the BMW R 1200 GS Adventure, made from 2006 onward (replacing the R 1150 GSA which had overlapped a little with the R 1200 GS.

The BMW R 1200 GS is a now iconic motorcycle, continuing the GS legacy of adventure motorcycles. The Hexhead generation is built around an air/oil-cooled 1170cc boxer twin that makes around 100hp, putting power down through a six-speed transmission and a shaft drive.

From 2010 to 2013, BMW used a new twin-cam “camhead” motor in the 2010-2013 BMW R 1200 GS and GSA models.

Maintenance for this generation Hexhead BMW is quite similar to that for other Hexhead of the same era, e.g. the BMW R 1200 R.

Maintenance schedule for the 2004-2009 BMW R 1200 GS

Below is the maintenance schedule for the BMW R 1200 GS Hexhead made between 2004 and 2009.

This maintenance schedule is presented in a different format in the manuals and various references. It’s consolidated into one table below for your convenience. The “Dealer” items are at the bottom because not everyone has a BMW diagnostic system.

Notes on the schedule

  • Some of the items have to be done every 10,000 km (e.g. change the oil, or checking the valve clearances), and some less frequently (e.g. change gearbox oil or alternator belt)
  • The original schedule is in KM in most markets; miles are added for convenience for US and UK riders.
  • The maintenance schedule for many items follows a “per x years” or “x distance” schedule. Follow whichever comes first (e.g. if you have the bike for a year and don’t put 10,000 km on it, change the oil anyway)

* Manuals for later models of the R 1200 GS recommend changing the alternator belt every six years or 40,000 km (shorter than 60,000), so do as you think is wise.

About the 2004-2009 “Hexhead” BMW R 1200 GS

The BMW R 1200 GS is BMW’s top-of-the-line adventure motorcycle. It caused quite a stir when it arrived in 2004 because it was more powerful, more refined, and a LOT lighter (30kg or 66 lb) than the outgoing BMW R 1150 GS, which already was very well loved (and still is).

In fact, the R 1200 GS became one of BMW’s most popular motorcycles, even in Europe which has no tundra to cross. BMW didn’t invent the “adventure touring” motorcycle category but they did become synonymous with it, thanks in large part to the R 1200 GS.

The early Hexhead BMW R 1200 GS had a bit of tech (ABS as an option, but a frequently chosen one, and also heated grips), but lacked a lot of what came with later models — no traction control, no ride by wire, no IMU, no Automatic Stability Control. So it’s still somewhat of a raw experience to ride.

The cockpit of the R 1200 GS in this period reflects the tech of the time. It has a couple of gauges for the speed and rpms and a digital display panel for other information.

The engine of the R 1200 GS makes 73 kW (98 hp) in the first years, and then 76 kW (105 hp) from 2007-2009. They feel much the same (although more power is always good), especially as your average GS rider will probably have weighed the bike down with luggage and accessories, dulling the impact of a few hp here and there. There’s torque everywhere in the motor. It’s not “revvy” but it’s also not dull, and can pull in most gears in the middle of the torque band. Some describe it as easy to wheelie, but it won’t loft its wheel into the air without you trying.

A nice feature of the Hexhead engine in the R 1200 GS is the counterbalancing shaft. This helps keep the bike a lot more vibration-free than the earlier R 1150 GS models. It still vibrates a lot, of course… it’s a boxer… and has that traditional kick over to the left every time you grab the throttle a little at a standstill.

Shifting on the R 1200 GS is very pleasant. Just like on any of BMW’s big bikes, really — you never have to “kick” it into gear, it just shifts.

One fly in the ointment of the R 1200 GS is the servo brake unit on the 2004-2006 models. This is often called “whizzy brakes” or “servo-assisted brakes”. You can feel the unit clamping down when you pull in the brake lever, helping you out. But the drawback to this system is that when it fails, you’re left with very little braking, which can be really dangerous. And repairing it costs thousands of dollars.

For this reason alone, among the hexheads, people prefer models that either never came with ABS, or which are 2007-2009 models. (On which ABS can fail — it always can — but won’t leave you stranded.)
