[250x_kyle]

im thinking about building a hybrid this winter.. I want to know waht i shoutld do should i use a stock 400ex frame put a yz426f motor in it and get a gusset kit or buy a aftermarket 250r frame. also what parts are entergchangable between the 250r and 400ex. thanks:D

Do you have any of the frames now? They're both going to be sweet, I personally would use the 400 because I like the plastics better. But many say the geometry of the 250r is much better.

the 250r dose have the best geometry but the 400 is also a very nice frame to use. i would also use a crf450 engine insted of a 426.
