So updating my previous thread for the assistance of others. ....

I went for the Avon distanzia tyres.
There is a supermoto specific rear tyre.
The tyres are absolutely brilliant on roads both dry and wet. The confidence they inspire and the level of grip are astounding in my experience. The grip and the lean angles I can achieve are very surprising. They have never stepped out of line once yet and I've pushed them hard on the road.
Off road on byways and trails they work really well but I have only used them in the dry. On gravel and rocks they hook up great for what they are and give a confidence inspiring drift from the rear. The front slips out on deep sandy gravel sometimes but I think most tyres would react the same. I haven't tried mud but wouldn't expect great things.
So far I have done 1500 miles mostly on road and I am hard on tyres but the rear has worn about 1.5mm which i am pleased with. There are a few small pieces of the tread that have come away but nothing to be concerned with. There are literally no chicken strips on either side of the rear tyre they are so confidence inspiring.

I would say for an 80/20 tyre to use on dry trails on a supermoto, you'd be hard pressed to better them.
They are not a cheap tyre but I think they are definately worth the extra.
