He is a special little guy, we started him out on a 125 Taotao with the throttle set screw turned in. When we had to weld steering support and then the frame it was time to move him up into a machine that had a better frame and other components. I had the 330 trail boss and 500ho scrambler so Polaris was my first choice. He has had his bumps and bruises but keeps getting back on and always asks grandpa want to go for a quad ride. The Taotao has been passed on to his 5yr old sister, she started riding it last summer at 4.5yrs and does real. Thanks for the reply and votes.
