I would welcome feedback from any K12RS pilots out there who are running on Michelin RP2s together with their recommendations for suspension settings and tyre pressures.
I've got 4,400 miles on a set and they're not quite worn out, but I have a 4 day riding trip coming up to the NC mountains and they won't make it back. BT021s came off for the RP2s and I have another set of BT021s in the attic ready to mount.
Can't help you much with suspension settings, but I've kept the air pressure pretty high, 42R and 40F. The front is looking much better than the BT021 after the same mileage, and the rears are about the same. Very little squaring off of either rear tires.
But the RP2s have cupped very badly. I've never had a rear tire where I've noticed cupping before these RP2s, and I can feel the vibration in turns. Front has not cupped tot he extent of a BT020 but the rear is quite extensive.
I'm hoping that I had the front pressure of the BT021 too low and that is why it was toast far before the rear. Mileage is about the same for the rear tires. If anything, I felt the BT021s were more stable, stuck a tad better, and had a softer ride.
If the new front BT021 goes away again as fast as the first set, I'll return to the RP2s. They quite nice.
