Hey! I'm Eric...been riding a Z400 for ages. Once I started racing hare scrambles, though, the poor thing just couldn't keep up! Picking up a holdover 08 DS450X tomorrow...can't wait to get it to the starting line!
congrats on the new quad! as always...make sure it has the updates and before you ask after that first ride, yes it sucks on the bottom end at first. cut the pink wire, open the air box and remove the sparky and youll find that hidden power plus more!
Before you buy it you might want to check in on the racer support program. I didn't know about it when I bought mine a month ago and now I can't get in. Plus if you get in before you buy they give yo a better deal.
