Metzler Z6 Roadtec
Had Z6s on R1100Rt and have them on current R1200Rt. Liked them on 1100 but not so sure on 1200. Will probably go back to Bridgestone Bt 20 or new Bt 21 if they are available when i'm changing. Always got 6000 mls out of tyres on 1100 but only got 5000mls out of original Bt 20s on 1200.
Regards,
Kieran.
