when you bike is new, the metal parts of your engine contains some rough edges. As you run-in the bike, they tend to create greater friction and hence the heat. This is normal in any machine.

As you run-in the bike, those rough edges get smoother & fits perfectly with each other. Those tiny metal scraps are deposited in the engine oil. Hence Engine oil is changed in First Service.

The speed limit is due to the fact, since engine is new, some parts may be loose and it may not be at your full potential, so at high speed, there may be some damage to the new engine. It is always better to follow the running in for better life of your engine. Some occasional bursts are not harmful, but don't keep running the engine all the way like that.

Your bike manual has some detail information about running in. Follow them.
