Derestriction... - GSX-R 400 RR SP?

Hey there...

I'm the lucky owner of this bike..

I've heard rumours that it's derestricted to 112 MPH (180 km/t), is that so??

My bike is fitted with at Red Rev Derestrictor Kit?
What does it do, maybe make it possible to enter the reed line on the rev'o-meter??

Does I need the Derestrictor kit (M Max) to get maximum power from my bike? What is this M Max system?

Pleas help a lost suzuki driver!
