BMW HP2 Enduro Maintenance Schedule and Service Intervals

This is the maintenance schedule for the BMW HP2 Enduro, an iconic enduro motorcycle from BMW powered by a boxer engine. This is from the service manual and other maintenance resources.

The BMW HP2 Enduro is from the HP2 line, a shortly-lived series of high-performance bikes.

Here are all the bikes in the HP2 series:

The BMW HP2 Enduro is powered by a 1170 cc air/oil-cooled engine. It has a single camshaft and four valves per cylinder. With a relatively mild 11.0:1 compression ratio, it makes 77 kW / 105 hp at 7000 rpm, or 115 Nm / 85 lb-ft at 5500 rpm — it’s more torque-forward than its stablemates.

Final drive is via a six-speed transmission and a shaft drive.

BMW HP2 Enduro Service Intervals

Basic service intervals for the HP2 Enduro are every 6000 miles / 10000 km or year. At every service, change the oil and filter, and check the valve clearances. The service guidelines recommend checking some items more often if you ride regularly off-road or in harsh conditions.

Other items are more infrequent. For example, only change the spark plugs every 24000 miles or 40000 km, though it’s good to check their condition against the spec (below).

BMW recommends you change the gearbox oil every two years, but doesn’t specify you should change the final drive oil. But based on practise of owners, and recommendations in later model BMW motorcycle manuals, every two years is still a good guideline.

Maintenance Schedule for the BMW HP2 Enduro

Below is the maintenance schedule for the BMW HP2 Enduro.

We’ve broken it up into two parts:

  1. The regular schedule of major items (oil changes, spark plug changes and so on)
  2. The list of standard annual inspection items

Notes on the schedule

  • 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 10000 km on it, change the oil anyway)
  • At the end of the indicated schedule, continue following it in the pattern shown.
  • [D] means items needing dealer tools

* The owner’s manual and RSD doesn’t specify this as a requirement. However manuals for later BMW motorcycles did, so we apply it retrospectively.

Annual checklist

Items marked with a checkmark in the “O-R” should be checked more often when riding off-road or otherwise riding aggressively

BMW HP2 Enduro Wheels and Tires

The BMW HP2 Enduro runs a 21/17-inch offroad-ready tire combination. Stock, it runs with “massive-bar” (blocky knobby tires) which are optimised for off-road work, rather than high speed.

Front90/90-212.2 bar / 220 kPa / 32 psi

The BMW HP2 Enduro is a quite unique bike for BMW. In some ways it’s like a BMW R 1200 GS but without a lot of other “stuff” on it, stripped back to its core. But it’s not the same — the wheels, suspension, brakes, and other core components are quite different.

When launched, the BMW HP2 Enduro was just known as the HP2, as it came before the other variants in supermoto and sport bike variations.

These were the three variants of the HP2 line and how they differed:

BMW HP2 Motorcycles core differences

The HP2 Enduro is powered by a single overhead camshaft four valve boxer motor. It’s of the earlier generation of boxer motors before the HP2 Sport introduced the dual overhead cam setup, which became the standard in BMW boxer motorcycles from 2010.

Despite being the “older” generation motor, the HP2 is tuned for relatively high performance, and makes both decent low-end torque and top-end pull, if you ever need it.

The manual for the HP2 Enduro says that 98 ROZ/RON fuel is recommended (super premium), but that it’ll run on basic regular unleaded (91 ROZ/RON, known as 87 PON / AKI in the US) with power and consumption-related restrictions. It’s good to know that you’ll have options, because an enduro bike with only a 13L (3.4 US Gallon) tank will need refilling pretty often!

A few things distinguish the HP2 Enduro from most other BMW boxer motorcycles.

Firstly, unlike the BMW R 1200 GS, the HP2 Enduro doesn’t have a Telelever front suspension. It has an upside-down fork, which has a different response — it doesn’t have eliminate dive like the Telelever setup does. However, it is a lot lighter, and contributes to the fact that the HP2 Enduro is quite lightweight (just shy of 200 kg / 440 lb with a full tank).

Secondly, the 21-inch front wheel is unusual in the boxer line-up. Even the adventure-ready BMW R 1200 GSA has a 19-inch front wheel.

Thirdly, the rear air shock is a pretty weird one. It’s an air/spring damper that actually works by flowing air through plates for a “spring” effect. You adjust it with a wheel valve and a bicycle pump! Or with a high-pressure pump that comes with the pipe.

Even though the BMW HP2 Enduro is an interesting bike, it has niche appeal at best. Sure, an air/oil-cooled motorcycle with a high-performance boxer and 21-inch front wheel sounds interesting on paper, but in practise its limited range, heavy weight, and air-cooling mean that it’s not the greatest off-road experience.

Nonetheless, the BMW HP2 Enduro has a lot of collector value and definitely gets a lot of comments when you take it anywhere.

The best part is that you can stick on some road wheels and have yourself a pretty feisty supermoto, as well.
