I went ahead and ordered Avons this time to try them out anyway from tireexpress.com. Obviously, if I don't like them, I'll be back to Metzlers.
OH.. I also know that the new Suzuki C109RT is running Bridgestone Exedra G852 rear tire. 240/55-16. I looked and looked for this, but coudn't find it readily available yet. Once this tire is available, I believe it will be cheaper. Although, I don't think it's V rated. They also have a G701 front tire, 150/80-17 for the Valkyrie that will fit ours.
Dang.. I should have called the local Suzuki dealer first..
