I used to have a 2005 r6 that I really liked and kept it for about 2 years, then finally bought a new 2008 r6. I rode my buddies 2006 r6 limited edition and hated it.. it had no low-end power at all. The new 2008 has (while not a whole lot more) enough more to tell a difference. Add the ycci chip and bam you got the first stock 600 bike to truly pass 170 mph. It´s a little rougher than most bikes, but well worth it to have this bad machine. A GOOD BUY
