I've had the typical '08 problems, weak battery, failed ignition switch and a leaky water pump. With exception of the battery (installed an Odyssey 625) the repairs were done by the dealer under warranty.
I hate that they came with 16" rear wheels since they are the most expensive tires made. And the clear coat on the wheels suck ass.
With those minor things in mind, it's still the best bike I've ever owned or ridden. I just love the big pain in the butt.
I saved my only real complaint for last ... dealer support in this area is AWFUL, just terrible. If we had a dealer that was larger, more factory trained and gave a **** ... I would give the R3 a 10.
So I give it a 9.
