Just got this for my 6 year old from a guy at work. $100 and runs great. Clutch sticks a little so this weekend I will be pulling it off and cleaning it up some. As well I will be adding an extra set of pedals so he can reach them and still have his seat belt securely attached. It has a 6.5 HP Tecumseh and is pretty quick even with daddy's fat 300 pound butt on it.
Now I also need to find him a used kid's dirt helmet to make sure he stays as safe as can be. If anyone has one sitting around that they don't need and you want to give away or sell, let me know
