I did the route today staring in Greene RI on my new SA 1290. I was a bit concert due to the 90/10 tires. Turns out there was very little dirt at all. Almost all tar except for barre and Wendell. Kind of a blur I have to admit. I didn't stop to take notes. The Wendell section was a bit tricky tho. A couple sections of loose washed out roads. I'll say the Ktm electronic suspension is pretty sweet. Selectable damping mad for pretty soft ride over the few whoops. But the nearly slick tires hab me dancing on the pegs.
