I have a Road Attack ll on the front of my 2005 X.
I like it, plenty of control, holds well. The bike is a good mix of responsive and stable. It certainly does not have the tippy feeling you get from the pilot power that was my last front. Mileage is about 3000km so far, I would expect it to go to 10000 but probably no more. I commute each day so around that figure I tuned to bake out tyres ( use up the heat cycles) anyway.

They are a single compound tyre that uses a progressive temperature curing to get the grip at lean angles, as opposed to other manufacturers dual and triple compounds. The tyre uses Conti's black chilli technology, also used on their bicycle tyres, which I also use and am very happy with.

I would be confident to use one again
