Usually you drain the oil out of the drain plug and then find out what kind of your oil. It takes an you fill it up until it starts overflowing, but I would ask the BMW dealership to make sure
The ABS lights can come on for a number of reasons, not least of which could be the condition of the battery, although I can't think why it should happen after travelling 500 metres. You may just get away with resetting the ABS system, the attcahed link shows how ou can do this ith ABS1 and ABS2, what harm could you possibly do? (answer; plenty, but the narator seems to know what he's talking about)

Jim, a little more info would be required.
Bike model and series. And I am not sure what you are referring to as the "Power Centre". Is that the starter motor or the engine itself?
Will depend on year, later models use a CanBus system, which replaced the fuse box, hence no fuses. If something trips the canBus acts like a fuse to protect what ever caused it to trip, turning off the ignition for 30 secs and back on again resets the system.
It may be a throttle lock. to find out, turn the throttle (ENGINE OFF) and hold it while tightening the screw. it should keep the throttle from closing when you release the grip. This is a very dangerous thing and should not be used EVER.
Usually, a rapid or immediate loss of power is indicative of a major component failure on an engine...and its something you should consider. Some tell tale signs, smoke out of the exhaust (note the color); or severe noises like loud banging and knocking- time for a major engine repair / over-haul.
On the other hand, perhaps what is happening is just coincidental to some other problem that was already in the making and was exacerbated when you snapped open the throttle.
Check the gas flow from the tank through the delivery system and filter- check the fuel shut-off valve, make sure it's fully open and that it is free of any clogs which would prevent the full flow of gas to the carburetor. Check the carburetor, see if the float bowl is full of gas; if necessary, check for a faulty fuel pump.
Another remote possibility is stale gas- was the bike sitting in storage for a while or did you use gas from a can that was lying around in storage...especially if it is of an ethanol blend that absorbs moisture.
Check the electrical system for ground shorts, spark plug cables for any deterioration and intermittent spark, check the CDI for either a weak, no-spark or verify a strong spark; and so-forth.
If everything is so far okay, inspect the engine oil; it should look smooth, glossy, and somewhat transparent. and run some compression tests.
Best regards.
