This has been around for ages now, its a Serb J22,
for those that thought it was a Tornado or a Jag, shame on you
closest people got before the Orao was mentioned were those that said the Mig 23 (again the Mig 27 looks more like the Jag because it was modelled on that

)
And so endeth the Air Defence lesson
The R1 had to back off because when then jet passed the bike (and i believe the bike was on the limiter showing 299kmh) it became too unstable, hence why the car overtakes the bike dramatically
As the story goes, the result was already known before they set off, it was going to be more a question of how dramatic the acceleration of the aircraft compared to the bike was going to be.
Good entertainment, but thats about it really as it doesnt prove anything other than power to weight again.
