This is the complete maintenance schedule for the BMW R 12 nineT, released as a 2024 model year onward.
The BMW R 12 nineT is ostensibly a replacement for the 2021-onward BMW R nineT (the “classic” high-end version). It has the same engine platform, but the chassis and suspension are different, with an angled rear shock rather than the upright one that the R nineT line had.
Like the bike it replaces, the BMW R 12 nineT has an 1170 cc air/oil-cooled boxer engine that makes around 80 kW / 107 bhp at 7000 rpm. The specs are ever so slightly peakier than the current gen R nineT.
Final drive is via a dry clutch plate and shaft.

Service intervals for the BMW R 12 nineT
Like the bike it replaces (and other Camhead models), the BMW R 12 nineT has relatively short 6000 mile / 10000 km or annual service intervals. At every service, you have to change the oil and filter and also check the valve clearances, plus do a series of other checks.
In recent years, BMW has been updating the service requirements of its boxer motorcycles, requiring more attention to the shaft final drive. BMW actually recommends replacing the drive shaft every 48000 miles / 80000 km, or as needed.
Luckily, the valve clearance inspection is only by distance, and it isn’t too hard on the R 12 nineT. Once you’re changing the oil at that point, it’s easy to remove the valve covers as they’re poking out the sides of the motorcycle rather than under a bunch of fairings. It doesn’t add much cost to the service.
Every two services, change the air filter and the spark plugs.
Finally, make sure to regularly replace the brake fluid.
What you need to service the BMW R 12 nineT — Consumables and Special Tools
For the BMW R 12 nineT, the manual recommends the following specific consumables.
|BMW R 12 nineT Spec
|Per the manual, you need a maximum of 3.95 L (1 US gal) L of SAE 15W-50, API SJ/JASO MA2. Additives (for instance, molybdenum-based substances) are prohibited, because they would attack the coatings on engine components, BMW Motorrad recommends BMW Motorrad ADVANTEC Ultimate oil.
|All BMW R bikes use a BMW/Mahle oil filter, part number 11 42 7 673 541. The best replacement is a Hiflofiltro HF164.
|NGK MAR8AI-10DS This is what the manual suggests. Make sure it’s gapped correctly to 0.8mm (get a gapping tool).
|Called the “Rear axle differential oil” in the manual. BMW recommends “SAE 70W-80 / hypoid axle G3”, but many hypoid gear oils work, e.g. Mobil 1 75W-90.
|Super annoying when this breaks! The part number is 11 31 8 528 385. It’s easiest to pick this up from a dealer.
This table will be updated as more parts diagrams are made available online.

About the BMW R 12 nineT
The BMW R 12 nineT is an extension and replacement for the already-iconic BMW R nineT.
BMW started the R nineT line in 2014. They took the twin cam engine from the existing R line (which has since been replaced by the liquid-cooled boxers) and bolted it into a stripped-back, naked sport bike chassis.
The result was a hit. A rumbly engine, reasonably low weight, a low-maintenance air/oil-cooled engine and a shaft drive… the BMW R nineT flew off the shelves.
BMW in 2017 added variants to the line, including some highly design-forward variants like the R nineT Racer.
But for the 2024 model. year, BMW revised the entire concept with the announcement of the R 12 nineT. There’s a new chassis, a new layout of the rear suspension, and two models — just the BMW R 12 nineT and the BMW R 12, a cruiser.
The R 12 nineT is much like the high-end R nineT (no sub-model). It has an adjustable inverted fork up front, a six-axis IMU, and cruise control — though cruise is now an option, not standard as it used to be. There’s also the option of a quick shifter, a first for the series from the factory.
But aside from that, the R 12 nineT is much the same as its predecessor. It’s a combinaton of old and new, with a rumbly air/oil-cooled engine that gives a torque reaction when you give it throttle at idle, but with a reasonably lightweight build, and enough keep-alive electronics to keep your loved ones happy you’re taking care of yourself.
The BMW R 12 nineT also comes with an optional digital TFT display, which is a first for the line. It’s thin and low profile, which somehow suits the aesthetic.
Existing owners of the R nineT have little reason to upgrade. I don’t think many who’d opt for a bike with twin gauges would be swayed by a digital display. The shock location change seems trivial, and people like the air snorkel on the right of the original R nineT.
The exhaust end is nice, though (never mind the larger underbody section), as is the pairing of spoked rims and tubeless tires. Tempting!
In terms of maintenance, not much has changed since the R nineT. But note that BMW has started recommending paying active attention to the shaft final drive. You have to plan on replacing it — for the R 12 nineT, every 48000 miles or 80000 km. However, BMW does say that this is subject to the condition of the final drive.
