Had these on a previous CRF250R, and they worked well.
Just put a new pair on my new CRF250R...the fit was pretty good, but the instructions are poor. You get a piece of paper about the size of a playing card, that only explains a few things. You'll probably have to assemble and re-assemble the brackets that mount to the bike frame, due to the poor instructions. But, once the finished assembly is on, they work well.
Be sure to attach the bolt to the frame first, then the radiator, then the upper shrouds, help get everything to line up.
