KYB or Showa Rear Shock
I am speaking of the shock (rear) only. I have WP forks up front. I have both KYB (2004 CR125) and Showa (2004 CR 250). Both are in very nice condition. Either one I chose I will only be "springing" for my weight (not re valving).
Does anyone have a recommendation on which of these shocks would be a better choice either from a "future build up" platform, or which may have better stock valving for what I am doing? Weight 220#, riding type Sand.
Any input appreciated.
Also Do you guys feel using the race tech suspension calculator for the cr125 (if using KYB) or cr250 (if using showa) for "motocross" will get me close for sand, and the 500 conversion, or should I get a little heavier or lighter spring?

From all my sand experience, and thats a LOT, almost exclusively what I ride, you should consider valving for your weight. Now I'm speaking from moto perspective, but sand is a pain if the suspension isn't set uo for you. Especially on the rear. Shock plows through the travel fast, even with the proper spring. If you are riding at high speeds in the desert, I would think that would be as horrifying as a whooped out sand track. I can't say what shock is best, perhaps it comes down to the mechanical condition of either. Likely though, the Showa is the better, I think it will have stiffer OEM valving being off a 250. If you absolutely don't want to valve.
I clicked on your build thread, got a 400 errror, so I can't tell what bike you have. However sag is sag, regardless of bike. I have an 04 450 chassis with a 5.9 spring in it, and I'm 265 in gear. That was the choice off their chart, and it was bang on for me.

Yup, that link worked. Remember it now. Your welder did an awesome job, that whole bike looks sweet. Not sure what to tell you on a spring choice, the 125 obviously would be lighter than the 500 motor, so whatever spring is recommended for your weight on that bike might be a tick off. Maybe by .1 or .2. Anyone you can swap springs with before you pop for the right one?
