It is foolish to take dangerous motorcycle rides by yourself.
Biff just bought an expensive new motorcycle to show off and ride on.
Biff wants to ride his motorcycle.
Biff plans safe riding routes with his friends and then shows off how fast it can go.
Biff rides the motorcycle and first time out he crashes into a tree.
Biff and his friends have a lot of fun riding their motorcycles.
Biff is fine but is motorcycle is totaled beyond repair, all he could do is buy another one.
