The title of this video is “Japan Police moto test”, but according to the comment, this is Gymkhana, bike trial competition.  Rider is Mr. Yoshinobu Shiga.  He seems to be the ex-motocross biker.   
Bike is Honda CBR600RR.  He controls the 599cc bike as bicycle…  better than that.

My jealous is reaching to the top…
How do we train for this?

It’s amazing technique.  Especially his knee is touching to the ground with low speed…

In Japan, this level of technique is required for getting the license!

Then, please let me know how to learn this technique!    +2

Please give me your opinion.  What kind of training do I need to do for reaching to this level?

First of all, you should earn money for fixing the bike without problem!

He might have many mistakes during his training.  Nothing venture, nothing have!

It’s nothing.  I have never see Japanese who become top at MotoGP.

Only Ninja and Ninja can do this kind of things! 

Canada
Well, I feel only Japanese can do this.

I think his technique is amazing, but please look at the chain wheel size.  It’s big, right,
It’s easy to control when he speeds up, and it helps him to have smooth driving with slow speed. 

USA
Japanese have something worse than us? 

Indonesia
Because they have these policemen, the crime rate in Japan is the world’s least, right?

Such an amazing rider!
I hope I could drive like him…
