At the risk of stating the obvious; swing out wide on the turn like you’re driving a long semi-trailer, make the turn later and tighter where you still have the clear pavement, straighten up the bike completely before you enter the gravel (if possible) and from that point exercise extremely smoother throttle control, engine or no braking at all while on the loose gravel corners.
Street bikes always feel ‘twitchy’ on thick gravel but it doesn’t mean you are going down, resist the urge to over-react, pucker up those butt cheeks, transfer your weight as low as you can and ride with it.
On my drivers test I was riding a full knobby dirt bike at the time and I wrote on the edge of the test paper, “wooHooo, roll on the throttle and do a big cat walk” …along with the correct answer. …The government really has no sense of humor, do they !
I just thought of another oops! … reaching down to put your spark plug cap back on at high speed in the pouring rain
