Yeah man , I do. I went to ride in Mendicino county ( north of San Francisco) Great place called middle creek. My buddy invited some friends and one of them was on a WR250x. His was the supermoto version with dirt wheels on it. According to this guy he bought it with all the possible mods for power already on it. A fuel injected bike with just air and exhaust. As far as I know there was no EFI map changing software added. SO anyways, dood couldnt ride for beans so I wound up riding his bike up the more difficult stuff and he hiked. I ride a WR250f aswell as my TW so I have a fair comparison.
-the 250x had pretty good smooth power with the fuel injection and mods. However, it was not nearly as powerfull as my WR250f (JD jetkit and exhaust)
-the suspension had less travel but felt alright. I am only 160 lbs.
-the seat hieght was as high as my 250f, for me at 5'8" that is tippy toes on the ground while seated.
Personally I would choose a different dual sport if I wanted a street legal and more power. I dont know what or where you like to ride but I have ridden a couple Kawasaki KLX250s' and they have an inverted front fork with 11" of travel front and rear like the full on dirt bikes. I really enjoyed those as the seat hieght was reasonable and more power than the TW by a long shot. Just a suggestion.
After learning to ride on the WR then switching back and forth from TW to WR and back (depending on who I go with) I have realized that you really dont need big power to be efficient. So long as there is traction that little TW will go anywhere my WR will!! Although there is something quite nice about, turn throttle, front tire goes up! Weeeee!
Hope that helps bra.
