Man I am between those M4's and gravesport carbon. I have a matte black with red accents 14' and the powder coating/satin coating on those M4's would really match the blackness of my bike. You say they aren't that loud without the silencers? I'm curious how you feel about them after a ride with a helmet on? I checked your pics of your old Raider, my other bike is an 09' raven Raider I was going to sell it, but I couldn't do it. So now there is two bikes in the stable. The way I figure it, once the newness rubs off the ZX14 I will be switching rather frequently. Give us a ride report when you have some time bro!
The Gravesports look good too, good luck deciding. I wish I kept my Raider, it was fun. But if you decide on the M4's, get the stage 2 baffles.
Check out this vid, M's with the baffles in.
