10 hp warter cool engine

[skyash]

I see a man selling a pocket bike with a 10hp warter cool engine has enyone ever seen one and the man says he get up 100kmh. I think the bike are called banshee. Enyone? And the hole bike is $250 but the pull start is broken so I don't know really if if goes. It's hard when you are buying from a back yard not a shop
