Both forks are rockshox. One has lock out, the other has remote lock out. Can I swap them around, and is it easy or are any special tools needed?
Yes, assuming they are both remote capable. Rockshox uses the same lockout on all the models I have seen. Should be no issue and will only take a small allen wrench. You will likely need to remove the grips, brake lever and shifter from your left handlebar.
IF the new fork is not capable you may need a remote lockout top cap, which is a bigger question.
