I had a rear go out at 7O mph. No issues, it must have gone down slow. Anyhow I am going to replace both tires and I have heard some good things about the Metzler Z8. I am just a weekend rider (200-300mi), with just a long ride once a year( 1500-2000). Oh yea, it an R1150R.
I would appreciate any comments on the Z8 or any recommendations on another Metzler before I hit the buy button.
