For the 25 pitch roller chain, I used the sketch formulas found in (I believe) Machinery Handbook and made a Solidworks equation driven model where you would enter in the chain pitch, roller diameter, and number of teeth and it would generate the CAD model.
After a quick Google search I found this PDF but I haven't verified the equations:
