I've got the green version(Kawasaki) and hanen't had any problems. It is a great all around bike. I put a frame brace on mine when I got it and the frame has held up well. I think it was made by Ahrens bros.(sp?). They did a write up on the brace in dirtwheels about a year ago. The factory skidplates are a joke(plastic) but I upgraded to PRM and they are really nice. I think the only time there is a problem with the frame is when you get lots of air.
Lots O Trikes!!!!!
