This motorcycle is a graduation from kindergarten present for my daughter. Its a really cool little 50cc gas pocket bike! Good quality build once you do a few tweaks, like swapping the fuel line and adding an inline fuel filter, swapping the spark plug, and backing out some critical bolts and using blue loctite to secure them. It will provide a great couple of years of fun and a safe way to learn balance and braking for my baby girl.
