Assuming that you have the same number of connections and that you can make it fit, the answer is yes, IF you use a relay from an equal size or larger motor. The starter motor for a 750 cc bike will draw a lot more amps than a 200 cc bike. Thus, if you used a starter relay from a 200 cc bike on a 750 cc bike you could run the risk of burning out the starter relay contacts.

so bigger to smaller is ok,

while smaller to bigger is not ok,
