Thanks for that info, I have a little one that has a 50 and it would have a place there but I also have a plain 4-wheeler for that. Just wondering if the z-400 was fun, fast, and handled well, even when we go out for the casual ride with my friends it always turns competitive. We ride some semi hilly, somewhat sandy, old and new fire lanes. Some are clean as a whistle and you can go fast some are becoming overgrown and need a little technique to get around the washouts. Would the z- be fun by myself "not competing with a bike cause we all know bikes are faster, just looking for the fun factor.We also have lots of water bars to jump, Can you go very far on a tank of gas, when we go off on our bikes someone usually runs out.
