People may say (parents,friends) that motor bike riding is dangerous but if you think about it, it really isn't. If you go out and respect the bike and stay within your skill range accidents rarely happen. If you choose to rip it up and try to accomplish feats that can not be done by your skill level then your at a greater risk to crash.
There's no such thing as a bike skill, even with a hack.
is a bike mechanical
Pretty good in favor of crashing. You ride a dirt bike for the thrill which means you push your riding ability. Sooner or later it does catch up with you.
You buy a new or used bike and either replace parts or modify the bike so that it suits your riding needs and ability. Most common areas are a different pipe and silencer and suspension work.
riding a bike can have an advantage over a plane because if you don't want to pay money than a bike is better and that riding a bike gives you cardio.

The person who is riding the bike dies...if you hit him/her hard enough.
Not after riding a bike, but rather during riding a bike. Your muscles convert chemical energy (a form of potential energy) into mechanical energy to do work.
