After 15,000 Km, the Bridgestones that came with the 2011 BMW R1200RT were just about gone. The rear was quite flat in the centre due to the big trip last June, and both tires were showing the start of the wear bars.
My service manager recommended Metzler and we settled on Z6 Interacs. $500 left me enough for a Starbucks. A small one.
Quieter tires. I can feel the difference between Comfort and Normal. Have not tried the Sport setting yet, as I wanted a few miles on them. I'm now in Watkins Glen and will try that on the way home. Handling is better than ever.
Will have to see how well they hold up, but I'm happy now.
