BMW F 650 GS (800cc Twin, 2008-2012) Maintenance Schedule and Service Intervals

This is the maintenance schedule and service intervals for the BMW F 650 GS Twin, BMW’s little sibling to the F 800 GS. The F 650 GS in this incarnation was made between 2008 and 2012.

We’ll call it the F 650 GS Twin to distinguish it from the earlier F 650 GS, which was based on the 652cc single-cylinder engine, later found in the BMW G 650 GS.

From model year 2013, BMW replaced the F 650 GS Twin with the F 700 GS, giving it a few upgrades which warrants a separate maintenance schedule.

The BMW F 650 GS Twin was powered by a 798cc four-valve-per-cylinder DOHC parallel twin engine — the same engine block found in its bigger sibling the F 800 GS.

But the engine in the F 650 GS was de-tuned, with peak power of 52 kW (71 hp) @ 7,000 rpm, and peak torque of 75 Nm, by way of power-reducing valve timing and an accompanying ECU tune. So it’s not totally neutered; though you can also get the F 650 GS Twin in A2 form that makes half that power, for those on restricted licenses.

Other changes to the F 650 GS compared to the 2008-2012 F 800 GS can be seen in the table below.

Maintenance schedule for the BMW F 650 GS Twin

Below is the maintenance schedule for the BMW F 650 GS Twin. It has been adapted to be a little easier to read and to fit this screen.

We’ve omitted the “running in” check as we assume your F 650 GS is no longer new.

The schedule is quite similar to the contemporaneous F 800 GS, except for not having to change the oil in the forks.

About the BMW F 650 GS

The BMW F 650 GS Twin was an all-new model when it was launched in 2007 for the 2008 model year.

It confused (and continues to confuse) the BMW motorcycle world because it was identically named to, well, the other BMW F 650 GS, which was so named because of its engine displacement of 652cc. This was no longer the case with the new F 650 GS Twin (the unofficial name), which had a 798cc displacement.

Another thing that changed between the two motorcycles is that the F 650 GS twin is distinctly more road-focused and beginner-focused. It has alloy rims rather than spoked wheels, a short fairing, and a detuned engine more suited to beginner riding.

Basically you have to cast the name to one side and assume that the new BMW F 650 GS is an all-new motorcycle.

In a nutshell, it’s an easier, less aggressively adventurous, and cheaper version of the BMW F 800 GS.

It’s powered by a 798cc dual overhead-cam liquid-cooled parallel twin, tuned to produce around 20% less power than the F 800 GS, though peak torque is the same and comes on around the same point (a few hundred RPM higher in the F 750 GS).

Since the engine is lower powered, the bike’s engine has a smaller radiator, and is only equipped with a single front disc. There are a number of other changes to the fairings and specs, some of which are for cost savings, and some of which are weight-saving — the F 650 GS is a total of 8 kg or 18 lb lighter than the F 800 GS. Coupled with the lower ride height, this makes the bike easier for newer, or less aggressive riders.

An unusual characteristic of the block found in the F 650 GS is the firing order. It has a 360 degree crank, which means one firing cycle for each crankshaft rotation. The pistons move up and down together. This means the sound is just like that of boxer engines, which have the same firing offset.

(It also means it sounds like a Triumph Bonneville T100, by the way! They used to have a 360-degree firing order before the the mid 2010s when the whole Triumph twin range went to a 270-degree crankshaft configuration.)

The pistons moving together leads to some vibration, which is smoothed out using a balance shaft. Despite this, the F 650 GS is still a vibey bike — something to be expected. All BMW adventure bikes share this characteristic.

The on the F 650 GS are alloy rims — not spoked, unlike the outgoing F 650 GS thumper and also unlike the F 800 GS. So it’s not designed to be for aggressive off-roading, through of course the little GS is still capable on dirt roads and so on.

In 2012, when BMW announced the updated F 800 GS, they also announced the upgraded F 700 GS, which replaced this model.
