I just rode my son's WR250x fitted with knobbies 8 hours of twisties, dirt roads, etc, was firmly convinced that I was going to sell my heavily modded DR650 to get one myself... Until I hit I40; after two hours of slab at 70, I was appreciating a larger displacement engine. That being said, the WR is an absolute hoot. Also rode the Honda, a very nice bike as well, but the WR has more guts, I would consider I a privilege to ride either of them.
Concerning the KTM; I would love to ride one, but due to the height, it's not an option, which proves to me that there is no perfect bike, what works for me might bite the wax tadpole for you.
By God, Woodrow; it's been one hell of a party.
