I am working through this now. The main question is, does a CRF wheel fit your forks? If the answer is yes, then you can get a CRF-X wheel, speedo drive, and cable, and it will hook up to your gauges and work normally. I am swapping 07 CRF 250 forks onto my L and keeping the stock instruments. I purchased an X wheel and everything bolts up and works well. You need the X wheel because it has slots for the tabs on the speedo drive, and you need the X cable because it is threaded on both ends. If the axles and spacing are same, it should work. BP the wheels from an X and crf will fit, but i already have a few spares from my cr, so to keep the cost down i was wondering if the speedo drive from the X wheels would fit the cr wheel.
