Wow. That's a serious upgrade, but I hope she won't be trying many tough single-tracks on that. At nearly 90 pounds heavier than the XT250, it may be harder to handle. I'm surprised she didn't go for a 350 Exec F, or a 500 Exec F, with a lot less weight than the XT, but their maintenance might be a bigger chore. Anyway, enjoy your Adventures . .
