320 miles of Sierra Nevada twisties today on the Motoz Tractionator GPS setup. The rear is a keeper. Very nice cornering and feels very natural, no squirming like the GoldenTyre GT723. The front is strange feeling. Turn-in is nice, but it has an unstable kind of wobbly feeling in corners. At about 100MPH there was a wobble that was pretty scary. I think this 320 mile ride is enough to break them in. Guess the hunt for a front tire goes on. Maybe a Pirelli MT90.
