Forget Evel Knievel! He's got nothing on the world's greatest daredevil, Hammy the Hamster! (Yes, the same Hammy the Hamster that went organic a while ago). According to Spot Motorcycles:
... no hamsters were harmed in the making of this extraordinary movie. Hammy announced his retirement shortly after completing this jump but, like many other famous daredevils, may find the lure of the spotlight to be too great to sit on the sidelines for long.
Fake, but cute.
I'd also disagree that this is cute, on the grounds that its not particularly safe. The gyroscope can also cause the bike to spin quite violently as it rights itself after toppling. Remember kids - stunts are best left to professionals and bendy toys.
(I know it doesn't matter, this is an explanation for those who say it's real)
