I have on on my 2010 SESG. Basically they make such an improvement on 08-down that it could not hurt. I had bought one for my 07, and the day it arrived I bought this 2010. So, I didn't want to ask for a refund (not their fault I didn't need the part) but they had to problems putting it towards one for my new bike. I see it as insurance. If it saves me from just 1 crash, it was money very well spent. Now, just waiting on my Ricor shocks.
