I made a couple of posts in the Templar resource guide on the rear shock link removal, with dimensions.
I think that a lowering link for a CRF250R or CRF230 (2000's models) will fit, but I haven't checked. I need to find one at a bike shop and measure the thing. If you can find one, or know someone with one, maybe see if you can get a micrometer on it to check if it is the same. I think 1" longer than stock (105mm plus 20-25mm) should be in the ball park for a 2" drop.
There are adjustable links for the CRF250R but they are not cheap (~ $180). But I am sure that there is a low cost aftermarket option. There must be one out there.
