I have an issue with tyre wear that I haven't been able to dial on out my 2011 Z1000. Currently running Michelin Pilot Power Pure's, although I had the same issue with the Previous Diablo Rosso's. As you can see from the image, the tyre is wearing unevenly and rolling the leading edge and lipping the trailing edges. This is more pronounced the closer to the edge of the tyre. Compression/Rebound seem to be pretty good at least from a handling perspective. Rider Sag is set at 30mm both ends although, I've had to wind the preload collar in almost all the way on the shock to achieve this so it's not perfect. Really need a heavier spring. Currently running 36/38psi cold although I have tried running 34/36 with similar results. My gut feeling was it's a rebound issue but I haven't been able to dial it out at least within the scope of the stock shock. Is there something I'm missing or is it just something to live with 'till I can justify putting a new spring and shock on the back? Edit: This tyre only has 1500km's on it and I dare say more than 1000 of that would have been highway due to a longer trip.
