I think I've fixed it
Over the past 2 weeks it's been between 28°C and 34°C and I've ridden almost every day between 100km and 260km.
Every afternoon I've put the industrial fan on to dry my jacket and helmet, the high pressure fan is also blasting the bike, and for the second week I've had no condensation or fogging of the speedo when out on the road.
Maybe moisture builds up after the ride and is still there for the next day? Whatever it is, I am going to keep running the fan 👍

My 2018 Heritage speedometer fogged up for 2 years. It didn't matter if it was cold, dry, humid, damp, wet, etc. It would fog up so bad you couldn't see the read out (fuel, gear indicator, clock). This is my seventh HD and none of my previous bikes had this issue--and I live in NC where the humidity is high in the summer. My dealer was absolutely no help at all with this issue, and refused to replace the speedo while the motorcycle was under warranty. I was ready to order the Dakota Digital replacement when I decide to try something. I figured I didn't have anything to lose, and my warranty had expired, so I removed the speedometer from the dash and drilled 4-5 tiny holes in the back; exactly under where the display would be located (it's easy to see where to drill). I think I used either a 5/32 or 11/64 bit. I took my time to make sure I didn't hit anything as the bit cut through the plastic. That was in July of this year, in the heat of the summer when our humidity is high. Since I did this, my speedometer has never once showed any signs whatsoever of fogging. This 15-minute fix saved me the cost of a new speedo and a lot of frustration. I love my M8 Heritage, but I was seriously starting to look at other brands.

Honestly, I didn't even think about that. I just took my time, used my variable speed drill and went slow. Most, if not all, of the plastic ended up on the outside of the case or on the bit. It's really pretty soft material. As I said, I had nothing to lose. If I screwed it up, I was going to buy a Dakota Digital. It's easy.

I believe it's not the heat of the engine but the sun heating up the instrument (black dial face, remember) and boiling the moisture inside. Then, when you start riding, the moving air cools the glass face, causing moisture to condense on the inside of the cool glass face. Mine shows the worst condensation on sunny, but cool days, where the bike is parked in the sun, then driven through cool air.
