I've done just under 11k from new on mine and the rear is down to 2mm of tread (front 3mm) - my dealer reckons I'll get another 1000-1500 miles out of the rear, but I'm heading for Spain next month and will do at least 1500 miles on the trip.
Anakee 2's seem to be the overwhelming favourites - can I get away with just changing the rear, or do I need matching tyres front & rear?
