New Tires = New Bike!
I changed the tires on my 2003 and it is like a new bike! The old tires were getting worn, but not real bad. It was a used bike and this is the first tire change for me. I put Metzler Z6's on, Dunlop Streetmax off.
I rode about 100 miles today and I'm still amazed. I also tried keeping the rpms higher than usual - closer to 5000. The bike drove completely different - in a good way!
I was beginning to wonder about all these great things you guys were staying about the 919. Now I understand!
I realize you more experienced folks will be saying, "Jeez, I told you so!" but until you experience it, you really don't understand.
