That is normal. When the engine temp reaches a certain level, the fan will kick on, and then when it cools down some, it will stop. Typically you are moving a little slower at the end of a ride, reducing natural airflow through the radiator. This causes the engine to heat up more and the fan will kick on. Then you shut the bike down, it is still hot, so the fan keeps running for a couple minutes to cool things off more. Perfectly normal.
