07 450 and 250 frame differences

(1/1)

belcher69:
Does any of you guys know the differences between the frames of the 250's and the 450's. I have a 07 450 frame which Im putting a k5 in. A very helpful member has made me some rails and a yoke but they are originally for a 09 250f. So I'd be grateful  for any info... Thanks

Dutch-K5 Fan:
450 cradle has more room for the bigger engine.
There are more detials, and  09 250 is different than 06-08 250.
I have AF with 07 kx250f frame. There's a thread about it here.
If you are planning to run a larger tank in the futere.
Use it with your build. I have to make new radiators.
Almost all self build af's are custom.

I understand  that dutchie but are the points were I cut out the cradle and the yoke the same?

Dutch-K5 Fan:
Don't know if it will fit. Think you have to measure
the frame and new parts.
