Looks like a four stroke, so i would say it has no restrictions, unless you count the exhaust as a restriction. However, i doubt anyone makes a performance can for it.

Hard to be sure without seeing the exhaust side. If its an aprilia red rose 125, then it uses the 2 stroke motor and i belive can be derestricted in the same way as an early RS125.
If it uses a 4 stroke engine, it can't be derestricted because it isn't restricted.

Hi

It uses the same basic engine as the RS125. Think they are in a lower state of tune, with a smaller carb and I doubt the exhaust is up to much. You can probably fit the power valve to it if there is not one currently fitted, and it might be easiest to fit the older pneumatic style power valve (available quite cheaply from Kart racing suppliers as they are used on the Rotax FR125 kart race engine).

All the best
