Rabmadjak30 is certainly right about the slow stuff being amongst the most difficult things you’ll have to master on a motorcycle; U-Turns especially.
I would add that, when going slowly, you must remember never to use the front brake when your front wheel is not pointing straight ahead or you will very likely drop the bike. Use the back brake only if the front wheel is not pointing straight ahead at slow speed.
At speed on the open road however, you should use both brakes together.
Another thing that nearly got me a few times when I was new to this, was stopping on a piece of road which was not flat left to right (e.g. some driveways on country roads). You may go to put your favored foot down (usually left), find no ground beneath your foot (because of the slope) and then the bike starts to tip over and you have a heck of a struggle to keep the bike from falling over when your foot does hit the ground (as a consequence of the bike falling over).
Another mistake newbie’s often make is to drive forwards into parking spaces. This is not a good idea as you will have less visibility when later backing-out of the space (than if you’d reversed into the space initially). It’s especially a bad idea if the parking space slopes downward (which is not uncommon). For one thing, your bike’s kick-stand (a.k.a. side-stand) may not hold the bike if you’re not in the habit of leaving your bike in gear. For another, it’s very difficult to get out of the space if your bike has no reverse gear (most motorcycles have no reverse gear).
