WR250/300 are in the same basic frame that has been used since 1999. It has had minor tweaks in 2002 but is essentially the same frame since 1999, maybe earlier. It isn't that it handles poorly at all it is just a matter of the new frames on the 125 and ex-lites works better.
Oh, That's too bad. The '01 CR250 frame worked really well IMO much better than the '00, I would still race one and wish I never sold my '01 CR250.
Given how much space there is in the '12 CR125 frame, what's to stop someone from shoehorning a WR250/300 motor in there? The swingarm bolt size/spacing? I think it would be phenominal........ NEXT PROJECT, WALT****************************************! I'll buy the first one!!
