As said before, the TTR is a trail bike. It's most at home with both wheels on the ground. The WR will hop, jump, and wheelie whenever you want, and isn't afraid of big air. I would use the TTR with e-start to mark (arrow) a trail in the woods, but I'd want the WR to actually ride the trail. The TTR is heavy and relatively low powered. Great for messing around and having fun on moderate terrain. The extra weight is not a good thing going down a slipery hill, and the weight and low power are a double hit in climbing anything steep and technical (its the opposite of a trials bike). I think that a much better bike for the money is the new Honda CRF230. Only 235 pounds, e-start, and from the recent test in REV magazine, it handles better than the XR250, is lighter, and close in power. Worth looking at.
