I bought a 2007 YZF600R last month and want to upgrade the seat. I really want a corbin seat and have heard great things about them. I looked on their website and noticed they only have listed up to a 2003 YZF600R. I called them and they are not listing the 2007 until, of course, one rolls into their California or Florida showrooms and has one fitted. I checked with Yamaha and they tell me the model numbers on the 2003 and 2007 seats are identicle but won't guarantee the 2003 Corbin seat will work on my bike. I'm hoping there is someone out there who has purchased a 2003 Corbin seat for their 2004 - 2007 600R and can let me know that it will work.
