I'm a believer in under body sliders. Ran off into kitty litter
(brake fade!) in turn 5 at RA with only some surface scratches to the fairing. Had they been through body sliders the pea gravel would have collapsed the fairing around the slider and cracked it. As it was the slider supported the fairing and the weight of the bike with only surface scratches.
Moral of this story is fast tracks like RA require racing type brake pads that wont vitrify under extreme braking conditions. I should have known better - lol
