Let's see some of those pictures. Esp. the 450R/CR500 quad. How much you goin to be asking for that thing?

i would use a 400ex chassis over the 450r, it handles alot better, and is lighter, if you get some LT elkas and arms and a aftermarket axel on there it will handle amazingly well, you almost never see crf450 hybrids in 450rs, its always in 400exs
