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! :)

Where would you get one of these GSXR400's? My wife is interested in a small cc bike but doesn't like the looks of the ones available in the US. Where was this bike offered? After a little research I see they were offered all the way up until 1999. I'd love to get ahold of one of these or an RF400.
