Tony - there are no dumb questions here...

I put this together a few years ago to cross-reference the letter underneath, catalogue number and description for each Scalextric Sport track piece...

Scalextric Border codes

I'm almost certain the track you're being offered is not compatible with the Scalextric Sport track in your Moto GP set. Not sure what it is - someone else my able to help there... Could be modern SCX (Spanish Scalextric track), which is quite different.
