Has anyone had any heat issues with these bags? I ordered a set for my new R1200GS, and will be mounting them on Touratech pannier racks. I'm just concerned about exhaust heat, since the pipe doesn't go all the way to the back of the rack. I'm aware of the aftermarket exhaust extension, but if it will be OK without it, I'd like to save $100 bucks.
Heat is a concern of mine because I had a set of Caribou pelican cases that actually melted ininto the mounting rack while riding on a hot day with a strong crosswind.
