This is the maintenance schedule and service intervals for the BMW R 1250 RS, released in late 2018 for the 2019 model year.
The BMW R 1250 RS is BMW’s sportiest of its sport tourers with boxer engines. The 2019 model replaces the previous R 1200 RS which had a liquid-cooled but smaller engine.
Still powered by a DOHC liquid-cooled boxer twin, the BMW R 1250 RS’s motor is now a 1254 cc (previously 1170 cc) capacity engine, putting out a peak of 100 kW (136 PS / 134 bhp) @ 7,750 rpm and peak torque 143 Nm (105 ft-lb) at 6,250 rpm, both of which specs are a rough ~10% increase over the outgoing 1200 motor.
Final drive is still via a shaft.
The 1250 motor is known as the “ShiftCam” engine as it has variable valve timing to help it deliver a broad spread of torque.
The 1250 ShiftCam motor in the R 1250 RS is used in other BMW motorcycles of similar vintage, like the BMW R 1250 RT, which was launched at the same time.

What you need to service your BMW R 1250 RS
The R 1250 RS is a very reliable, durable motorcycle — in fact, it’s used by some police forces for their high-speed chase bikes.
Servicing the “ShiftCam” BMW R 1250 RS requires many different parts to the earlier liquid-cooled R 1200 RS models. The parts list is also slightly different to other 1250 bikes.
Here’s what you need to service your big RS.
|Part||BMW R 1250 RS spec|
|Engine oil||The manual calls for “SAE 5W-40, API SL / JASO MA2” without additives, preferably BMW Motorrad oils e.g. BMW Motorrad Advantec Ultimate 5W-40. A well-respected alternative is Castrol Power RS 5W-40.|
|Oil filter||BMW part number for the oil filter is 11427721779. The HF160RC is a drop-in replacement from Hiflofiltro.|
|Rear drive oil||Use a high-quality API GL-5 synthetic 70W-80 hypoid gear oil, though many BMW mechanics use 70W-90. A high quality choice is Castrol 75W-90 synthetic that many dealers offer.|
|Spark plug||Standard spark plug is an NGK LMAR8AI-10 per the manual for the 1250 motor.|
|Air filter||BMW part number for the air filter is 13727726799. The K&N BM-1113 is an aftermarket alternative.|
|Coolant||The manual doesn’t mention what type, but get long-life BMW coolant from a dealer or online.|
|General lubricant||Use lithium soap-based grease to regularly lube external pivot points.|
|Brake fluid||Specified fluid must be DOT 4, e.g. Castrol DOT 4 or BMW DOT 4 fluid. BMW part number for the brake fluid is 83132445461.|
|Brake pads (front)||Part number for front brake pads is 34118548028 (you need two pairs). An EBC alternative is FA630HH (double sintered, long-life).|
|Brake pads (rear)||Part number for rear brake pads is 34218562163. An EBC alternative is FA209/2HH (double sintered, long-life pads).|
Maintenance schedule for the BMW R 1250 RS
Below is the maintenance schedule for the BMW R 1250 RS, presented in a simplified format from the manual, as it’s unnecessarily repetitive there. The maintenance is consolidated into one table below.
Things to note:
- There’s no alternator belt to change in the 1250 engine (unlike earlier models)
- You change the rear bevel gear oil every 20K km/2 years
- Valve service intervals are 20K km/12K mi, wider than earlier air/oil-cooled models
One interesting thing is that BMW doesn’t mention changing the coolant, just checking it. BMW uses a “permanent” (OAT) antifreeze that isn’t meant to be changed. Various dealers/mechanics still say you should change it every 3-4 years, though. Especially if you notice the level decreasing.
Notes on the schedule
- The running-in check is omitted (Dealers usually do this during the warranty period)
- Past the end of the maintenance schedule, keep following it in the pattern shown.
- The maintenance schedule for many items follows a “per x years” or “x distance” schedule. Follow whichever comes first.
|km x 1000||10||20||30||40|
|mi x 1000||6||12||18||24||Every|
|Conduct standard BMW annual service (see below)||Year|
|Change engine oil and filter (BMW Motorrad Advantec Ultimate 5W-40, HF160RC)||X||X||X||X||Year or 10K km (6K mi)|
|Change oil in rear bevel gears||X||X||2 years or 20K km (12K mi)|
|Check valve clearance||X||X|
|Change all spark plugs (LMAR8AI-10)||X||X|
|Replace air filter element (BM-1113)||X||X|
|Check or replace air filter element||X||X||X||X|
|Change oil in telescopic forks||X|
|Change brake fluid, entire system (BMW DOT 4)||After 1 year, then every 2 years|

About the BMW R 1250 RS
The BMW R 1250 RS is the latest in the series of sportbikes that started with the R 100 S back in 1976 (for the 1977 model year).
A lot has changed since then, but the fundamental concept of a boxer-powered fully faired comfortable sportbike hasn’t changed fundamentally.
But a lot has changed since even the R 1200 RS of a couple of generations ago. It was only last generation that the R 1200 RS got liquid cooling, and now the R 1250 RS gets a bigger engine and variable valve timing, for and even better spread of torque than before.
The R 1250 RS shares an engine with the concurrently released R 1250 GS and R 1250 RT. It’s a 1254cc boxer twin that’s liquid cooled and has dual overhead cams and four valves per cylinder.
In all three bikes it puts out the same power — 100 kW (136 PS or 134 bhp) at 7750 rpm, and a peak of 143 Nm (105 ft-lb) at 6250 RPM. These specs are a significant bump over the previous 1170cc liquid-cooled engine.
The motor has some improvements to mean that maintenance is even easier. The camshafts are driven via a toothed chain. Cooling and oil supply is improved ,and the knock sensor system is optimised for travel.
Brakes are Brembo 4-piston radial-mount calipers biting 320mm rotors — sportbike spec.
The R 1250 RS has really advanced suspension in the higher-spec models — Dynamic ESA “Next Generation” which has fully automatic load compensation. They’re 45mm inverted forks, and the rear suspension is a BMW paralever with remote preload and rebound adjustment.
The Exclusive package gets you a huge number of additions — cruise control, Dynamic suspension, a quick shifter, Riding Modes Pro, and more.
Manual for the BMW R 1250 RS
The above maintenance schedule comes directly from the 2021 manual for the BMW R 1250 RS, with parts references coming from parts fiches.
We checked both the 2019 and 2021 manuals to make sure it hadn’t changed.
