My dad just got himself a used 2008 YZ450F. And since Christmas is right around the corner, I thought I would buy him something nice for his new bike. My price range is between $50-$100. I realize that isn't much money but I don't have much money to spend so I want to make it count. And since I don't ride a four-stroke or know anything about them, I thought I would see what you guys say. Please help me.
