Avon rear is a great handling tyre in the dry. It's big advantage, if that's important, is that it comes in OEM size. However, I found it lost traction too easily in the wet. 50% better mileage than a Metz. I ran two of them.
The Exedra Max is a better tyre all round. As good as Avon in the dry and so much better in the wet. The higher profile is all a big plus too. Softer ride and I think the taller gearing made the Rocket more controllable coming out of a corner. It's the size the Rocket should have come with. It's also flatter and has deeper tread so gives about another 50% mileage over the Avon. Although it's a 240, it is also actually a little bit fatter than the others. Lost count but must have used at least 6, always with an Avon on the front - except for 1 time I tried an Exedra (not a Max and not recommended).
