Here are some pics of the stress on my frame. I am a mx rider and caught a dirt wall with my left front tire (standing in front of quad) while i was roosting arond it. my tires were turned all the way to the left (standing in front of quad) when i cauglt the dirt wall. It hit pretty decent. but I've hit stuff harder with my Z400 and not had any probs. After this I had a tight spot in my steering. As if I had a bent tie rod. After removing and inspecting my tie rods. I discovered they were perfect. I had stress marks by the bottom steering stem holder. I took it back out an took a couple slow laps. After those laps my tight spot disapeared. I've rode it for about a month since. I think this could be a problem. I check mine after every ride. Please don't turn this out of hand. just warning you about a possible problem.
