This is the complete maintenance schedule for the BMW HP4, released in mid 2012 (see official press release) for the 2012-2013 model years. It’s distinct from the BMW HP4 Race which was released in 2017 for that year only.
While it shares a lot with the RR race bikes, the HP4 is technically a successor to the boxer-powered BMW HP2 Sport, which in turn had more in common with the BMW R 1200 S. But the HP4 is the first four-cylinder HP bike.
The BMW HP4 is a race bike based on the already very race-oriented BMW S 1000 RR. It shares the inline four-cylinder engine of that bike — a liquid-cooled DOHC 16-valve engine that makes 142 kW (193 hp) at 3000 rpm, with maximum torque of 112 Nm (83 ft-lb) at 9750 rpm — but with tuning to increase midrange torque.
The BMW HP4 is distinct from the RR in that it’s built to be taken to the track immediately, with much lighter unladen weight (199 kg DIN unladen), due to lighter wheels, carbon parts, and exhaust. It comes standard with a lot of tech including Race ABS, standard DDC, Launch Control, race information on the console, a shift assistant, and more.
The BMW HP4 was made for two years, and was later succeeded by the BMW HP4 Race in 2017.

BMW HP4 Service Intervals
Overall, BMW HP4 has 10 000 km / 6 000 mile or annual service intervals.
Simplified, the maintenance schedule for the BMW HP4 involves:
- A standard service every 12 months (irrespective of distance)
- Oil change every 10,000 kms or 12 months, whichever is earlier
- Valve service intervals of 30000 km/18000 mi, at which point you check the timing and change the spark plugs, and also change the fork oil
- Changing the brake fluid every 1-2 years
That’s for regular, street use, though. If you plan on tracking your BMW HP4 (as many do), then maintenance will be more intense. See below for the track-specific maintenance recommendations from BMW.
What you need to service the BMW HP4 — Consumables and Special Tools
For the BMW HP4, the manual recommends the following specific consumables.
|Engine oil||Similar to the S 1000 RR, the BMW HP4 needs, 3.5L of SAE 5W-40, 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 5W-40 oil.|
|Oil filter||All BMW S bikes use a BMW/Mahle oil filter, part number 11 42 7 721 779. Available from Amazon. You can also use a Hiflofiltro HF160RC as a drop-in replacement that you can tighten or remove with a normal wrench.|
|Engine coolant||BMW recommends BMW Antifreeze/Coolant, with minimum 50% mixed with pure demineralised (not tap, not mineral) water. It’s based on ethylene glycol. But importantly, BMW says to never use coolants with nitrites or amines, those that “heal” the radiator, or a number of other solutions.|
|Spark plugs||NGK LMAR9D-J. This is what the manual requires.|
|Air filter||The part code for the air filter is 13 71 7 717 842, but a popular aftermarket air filter for BMW bikes is the DNA air filter, which has part code P-BM10S10-0R.|
|Brake pads||Use the standard brake pads by Brembo, which you can order from your dealer (34 11 8 534 234 for front, or 34 21 7 722 884 for rear). Or use EBC double hardened brake pads, a double set of FA447HH for the front, and FA213HH for the rear.|

BMW HP4 Tire size and pressures
The following are tire sizes and tire pressures for the BMW HP4.
Of course adjust the pressures according to conditions, your weight, and style of riding. Being a track-focused bike, most people fit very sport-oriented tyres to their HP4 bikes, if not slicks.
|Front||120/70 ZR 17||2.5 bar (36 psi)|
|Rear||200/55 ZR 17||2.9 bar (42 psi)|
About the BMW HP4
Seeing that the BMW HP4 is heavily based on the BMW S 1000 RR, to the extent that it shares the same motor, would make one naturally wonder: Why choose the HP4 over the S 1000 RR? Or why not modify the S1KR to make it an HP4 of your own?
Both the BMW HP4 and the S 1000 RR are based on the 999 cc liquid-cooled DOHC 16-valve inline four-cylinder engine, with a chain-and-sprocket drivetrain and regular (inverted, though) forks as suspension. In other words, they’re both what you expect from an I4 superbike.
But the BMW HP4 is much more track-focused.
Here’s what’s different between the BMW S 1000 RR and HP4 in a nutshell. The BMW HP4 has:
- More mid-range power. The same peak power and torque, but an engine tuned for more power between 6000 and 9750 rpm. The engine also has the same throttle response and full power output in all ride modes (but other characteristics change, like ABS/traction control).
- Less weight: 199 kg wet weight (90% DIN unladen), compared to 206.5 kg for the 2012 BMW S 1000 RR (both including ABS). This came primarily via lighter 7-spoke forged alloy wheels, a lighter sprocket carrier, a titanium exhaust system, and a lighter battery.
- Standard Dynamic Damping Control (DDC). This became available in the 2015 BMW S 1000 RR, a few years later. The damping parameters automatically adjust based on road characteristics and riding style.
- Race ABS with an enhanced “Slick” mode — the “IDM” setting configures Race ABS with specific parameters, obtained from experience on the track, to optimise the HP4’s ABS for track use.
- Larger rear tyre — a standard 200/55 ZR 17 tyre. The S 1000 RR has a standard 190/55 ZR 17 tyre.
- Launch control — a feature which also came later to the S 1000 RR
- Lots of aesthetic changes, e.g. different windscreen, LED turn signals, various stickers, carbon fibre bits, etc.
In 2014, BMW started letting you retro-fit cornering ABS to the HP4 from 2012.
The Competition package added a few more nice bits, like a spoiler, different wheel colours, and hinged levers.
Aside from that, the BMW HP4 is what you expect: a race bike that you can still register and ride on the roads.
If you’re bamboozled by all the above, the important thing to note is that the Dynamic Damping Control (DDC) is what makes the HP4 stand out from its contemporary, the 2012-2014 BMW S 1000 RR.
The DDC adjusts rebound and compression damping as you ride. It detects how bumpy the road is and also how you’re riding and adjusts the damping for maximum traction.
The DDC system doesn’t just measure speed and acceleration/ deceleration. It takes input from an IMU that can also feed it information about pitch and lean angle. Because the BMW HP4 has an IMU already, BMW offered in 2014 the ability to retrofit these bikes with cornering ABS (ABS Pro in BMW nomenclature).
The HP4 was the first bike to race with front and rear electronic damping. This is now a de rigueur feature on high-end sportbikes.
Just in case you’re wondering — yes, the BMW HP4 has heated grips. But no cruise control.
