With 5800 miles on the OEM B'Stone front on my 2 month old 2009 C14, I'll be lucky to get 7000 so I've got Michelin Pilot Road 2's on order. While checking the front forks, I noticed that two of the four "Front Forks Clamp Bolts (Lower)" were not tight and one of the two Front Forks Clamp Bolts (Upper)" was also not tight. The Periodic Maintenance Chart in the factory manual calls for checking "Bolts, nuts and fasteners tightness - inspect" so I'm putting the fork bolts at the top of the list. To re-torque the lower bolts with a torque wrench to factory spec., you'll have to remove the fairing but you can use a 10mm box wrench to check to see if the lower bolts are tight. After a 300 miles test ride, I think tightening the bolts has improved the handling, maybe it will help the tire last longer.
