keep an eye on your spokes. I had one come loose and detach itself from the rear wheel. This after 700 miles from the initial 600 miles service that stipulates spokes must be checked for tension. Dealer has submitted a warranty claim to Yamaha, looks like some other spokes are a touch loose as well.
I suggested to the service manager that the bike hadn't been checked properly, either at PDI or 600 mile service, maybe both, his reply was that it wasn't in the service schedule (it is)
needless to say I have lost all confidence with the dealer.
