As I previously mentioned I've put Pirelli Scorpion Rally STR 120/70-18 and 170/60-17 on my TDM900 .
Now they are tested after 6000km ( 400km off road and more then 500km very mixed bad roads (stones,gravel, old asphalt)
Tested on dry roads , mud, gravel, stone roads, in the havy rain (temp range fro 3Celsius to 30C). This is during last week trip to Turkey, Bayburt road D-915, Kemaliye tas yolu, ....
This is very very good tyre for all conditions, I would rate them 40% offroad 60% road...more then good enough..and they last , front in moment 5-6mm rear 7-8mm. So they lost 2-3mm.
