I am a great fan of the 3D XMs, and have used lots of them on the big V. No complaints at all with them. And as Rick states, they are capable of mega mileage. Quick tip though, the latest Avon Spirits are almost the same tyre as the 3D XM, but the front has 2mm more tread. So it makes sense to use a Spirit front with a 3D XM rear. And that combination is approved by Avon.
