the most common on two strokes is a little insert welded into the exhaust, usually just before the expansion chamber,

in my aprilia Rx50 is was cone shaped, and required an angle grinder to be removed


in the nsr's its a longer piece of metal requiring various drill bits to remove it..



take note if you remove the restrictors you may invalidate any warranty your bike has, if its new.

With a lot of the newer 50cc's, its, as Simple said, a small cone welded into the exhaust.

On some bikes (well the new Derbi's at least) also have a very large rear sprocket to lower top speed even more and a small air box which limits airflow.

Really though, you dont want to be messing around unless you know what your doing. Get the facts about your bike first, then figure out the plan of action.
