I've alwayd used Metz on my Tourer , but got crap mileage , Usually around 7-8000 KLM on the front and 5-7 on the back , I found the front would cup well before they wore out .
My lat set was the last straw with Metz 7000 out of both the front and rear no cupping this time just plain wore out , so i put the Exedra on , went on a long journey , , hundreds of klm on the straights followed by hundreds in the twisties ,, lots of rain and slippy roads, and they handled very well ,, i done around 5000 klm and there is plenty of tread left ..
Just be VERY VERY careful for the first 200 klm or so , when i left the dealer they were that slippy it was like being on ice .
Overall they appear to be lasting better than the metz and they were around 150 dollars cheaper for 2 tyres ,,
On a side note how the hell do some of you guys manage to get 10000 miles out of them , thats 16000 klm .. What do you do put the bike in a trailer and tow it round
It must be better road conditions , i can't think of anything else .
