Oh fount of all knowledge that is embodied in UKRM - I humbly beseech you for wise council I've an R1150R and been running Michelin Macadam on front & rear (170/60 ZR17) and now need a replacement on the back. I guess the obvious choice would be to replace like for like, but the Michelin web site recommends the Pilot Road or Pilot Sport Anyone had any experience with this tyre - I need something that's not going to square off badly as I teach CBT, this means I spend a lot of time very upright between 20 and 40 mph, however once off duty, have been known to put the engine on the deck and don't want anything to let go. Thanks GM (R1150R)
