To me the trail 3 are "just" road tires eventhough are sold like 90-10 but I don't see how to be helpful on off-road...
The Road Attack are even better and gripper, I am actually surprised that one can get the same km- miles as the others Continental.
My brother on his Hornet 600 has had road Attack 2 and they were good.
My brother in law has had the road Attack 3 at the same time, more performing bike (998cc against the 600cc) and very pleased.
I don't recall the milage though not being my bike...
I used to swap my previous bike with his Ducati and all I can say both bike and tires, in my opinion , were outstanding...
