2017 CRF1000 manual w Rally livery
Was up there on July 24 in the heat on a technical WABDR section using same Dunlop tires as OP on an AT. Almost died from the heat as I was keeping up with 2 fast moving KTM 450's (my bike was unloaded). My Rear tire has about 4K and doesn't look quite as chunked as yours. I run with a few lbs less pressure than you. My main issue (and it could be the Karoo on the Front....?) is a loud howl on tarmac between 50 and 55 mph. My Rear tire also feels very stiff to the touch and it about 1 yr old. Am going to try diff tires soon as the howl is exhausting.
