Yes, on stock tires and a new bike, under no throttle whatsoever. Spooked me.
Makes me mad that this has broken my confidence in "turning and burning" with the Busa... Gonna rough the tires up a bit with sandpaper and try again. Wasn't riding aggressively at all... just going around the long driveway/road into my apartment complex. Have gone faster on the curves on my Ninja 250.
Dealer set pressure at 42, front and back.
