Yes it is all stock XP900 and Motor ,the only after market part are the Dragon fire streeing wheel ,seat and today i did put a Dirty Dog clutch kit in it. No turbo right now because I'm saving a little over 200 pounds not putting all that plasic crap back on,plus the frame is all chromemolly ,small,stronger,and lighter,also lowerd the seat 9 inchs not helping weight but better center of gravity, that should add to the power to weight Ra.
I know alot of Razor lovers are not going to like this build but keep in mine im not using this car for anything but racing although it would make a fun trail rider too, the frame still has stock ride height.
