Had to replace my rear Sirac at 4500 miles when it wore out then the front at 6 thou - good enough tyres but the front had the bike handling like a pig for the last thousand miles.
I put a Tourance on the rear but it doesn't look like she'll last as long as the Sirac did. Running a Pirelli in front - think it is an MT90 but it was all I could get at the time. Both tyres are working well and the new front has made a tremendous difference on tarmac and on forestry roads - amazing what new rubber does for your confidence
