The only reason I got the upgrade kit with cams and stuff was my salesman (Ed at Commonwealth) threw them in with the bike for 20K. And he threw in the CF breather box and the valves in. I just decided to get the piston at the same time because I talked to the dealership here and they told me they dont do that kinda stuff for ducatis. I want somebody fully capable to install them, you know peice of mind. I paid 22,671 for my bike and thats including shipping. The shipping only takes 5-7 bussiness days and the bikes in Kentucky. If you need any parts talk to Ed at Commonwealth, by far the best salesman I've ever dealt with.
