I just purchased a KFX 50 for my daughter (4 1/2 yr old), man this thing is really nice. I lookied at alot of the other makes with more standard equipment but they just didn't seem as nicely built as the Kaw/Suz. I know that the motor has been around forever too which sealed the deal for me. She really does well on it too...the controls and smaller size makes it perfect for her without going to a mini with NO ground clearance. So far so good with it and she gets better everytime we go out. Any tips on keeping this little monster in tip top shape would be greatly appreciated!
