i had a 520 chain and sprocket conversion, new levers, bmc race air filter, penske emulators and piston front fork conversion, bazazz z-bomb, galfner front and rear braided brake lines. I believe that is everything...It's an awesome ride, love it.
All I can say is....it's an awesome machine straight out of the box! The honda is my 4th liter bike and as of right now, I wouldn't traded for anything. The bike is very agile, powerful, light weight, loads of great features. There has been some remarks made about the fact it burns oil....haven't noticed it at all. It does lack some features that bikes of the same yr. do have. It doesn't have a gear indicator and no throttle select maps. Not a deal breaker IMO. I will tell you this, it has an enormous amount of power and it's even detuned compared the euro model. I can't say enough good about. O yeah, it's very comfortable also.
