Both versions, new and old ones. They are my favourite tyre at the moment. I do not do track days though.
couldn't get the 200 rear so getting the new metzeler m7rr coming tomorrow I think so will let u know what I think when get fitted
I just finished off a set of M7RRs on my other bike (K1300S). They lasted 2800 miles pushed hard, but performance fell off at 2200 miles with about 1mm to go to the wear bars. But what a beautiful and fantastic tyre! Stable, transition from edge to edge superbly, great bump absorbtion, superbly grippy in the dry, and excellent in the damp. I will likely run M7RRs as my next road tyre on the Duc.
Tried to get the M7 fitted to my K13 earlier this year,but coulden't get hold of them at the time. Just as well my m5 normally do 3-3.5k. But will look at the M7 or M5 for the Duc
In fairness, I think the M7s would last longer for the majority of riders and 4k+ road miles should he easily achieved.
