Just kidding!

Anyways, I'm looking at a NSR MC18 but there seems to be some issue with the model.
On the Model History page there is no MC18 SP, but the guy selling the one I like is saying that it is a MC18 R4J SP?
Is this a real model or a hybrid?
Since the asking price is $5k AUD I figured I better ask some one.
