i dont recall eric (alba dude) telling me anything about a 450cc kit. he basically told me that it had a full yosh exhaust, and all the zook stuff on it like graphics, lights, nerfs, heel guards etc. he said that the bike that was all done up (one im talking about right now) was well over a year old, thats the one that they take around to shows and stuff. Ive got pics of it the very bike. I dunno though, i hope its not BS!
