I bent mine over the winter too so I won't ask. I bought a set of Renthal's off Amazon and love them! I could feel a small amount of vibration in the factory bars, but nothing with the Renthals. I saw something red on the inside when I looked into the end, so I'm assuming some sort of plastic/polymer fill that dampens vibrations. I've been out 4 or 5 times since I got them, and am very happy with them. Just waiting on a longer brake line. I was able to re-route the factory one to make it work, but it's tight and I want to move the brake lever out another half an inch. (The Renthal bars are 2-3 inches longer.)
I ended up getting a set of steel bars on eBay. They are about 3 inches wider. Only had to crack the brake hose banjo and move it a little. All works nicely. Now to have the couple of small dents taken out of the tank as a result of the “incident” and I’ll be happy.
