Went riding with Ed today, a seasoned enduro rider: Some nice riding with some nice views, and some fall color. But not in that shot. I tried his bike, a wr250r (not the street legal one) and it is very nice, runs like a 2 stroke, a very noticeable power band and not much torque. Just pin the throttle and work the 6 speed trans and roost all over the place. I would get hurt on that bike. I did well on the TW: 65F to 70 or 75F, no dust, firm sand from rain last night, but not enough to fill the mud holes, so a very good 60 mile ride. I run about 10 psi in my tires. A flat in the front would be no problem at all, just ride it out, the Shinko tires are tough and stiff. The back tire would be a problem... I never balance dual sport tires and never had an issue. The heavy duty tubes can make it very hard to balance. The one I bought is incredibly heavy and thick. I would never use it in the front.
