Hi m8 the last pic with the bags next to the exhaust reminds me of my earlier bike gpz500 me an the Mrs was on way up to Scotland an I had bags like this but I made a small platform with 1/2 inch gap between each alloy plate to stop the bags touching the exhaust I got less than 100 miles and R1 came along side me I'm doing 85mph and he's pointing to the back my bike so I pulled over mrs climbed off the bike as I did the right side bag exploded .the Mrs had large can hairspray in the bag an her clothes they was all over the hardshoulder of the M6 on fire.
The heat off the exhaust went up thro 1/4inch alloy thro 1/2inch air flow gap thro another 1/4inch alloy plate an boiled the hairspray can to exploding it . So seeing your bags on the exhaust be careful they don't burn .
