what rims interchange with raptor ones?

what can i do to lighten my raptor up?

 

YFZ450, Banshee, Warrior, other Raptors. There might be a few others, but those ones I know for sure. To lighten it up, depending on how far you wanna take it, just lose everything you don't need for the bike to be rideable. (ie lights, heal guards, e-brake, etc.) You can also buy aftermarket parts that are lighter if you so desire.
