The video - part of a series - features Dakar veteran CS Santosh, introduced as 'India's most accomplished off-road racer'.
He says: 'The first thing we were trying to look for was if the bike felt at home and if it didn't feel alien off road. Most of the time you have motorcycles that do well on the street but as soon as you take them off road they don't seem to fit in.
'But I was surprised because I think it felt natural to be off road as well...
'For the common man it will not be intimidating because the power is there but it's not going to be aggressive.'
It's expected to make around 28hp.
The video was posted moments ago on Royal Enfield's official YouTube channel with the message: 'C.S.Santosh, the only Indian to have completed the gruelling Dakar rally, puts the Royal Enfield Himalayan through its paces. Watch as he tests our latest machine and shares his thoughts on what you can expect when you head off-road with the Himalayan.'
Another official video has been posted here.
The promo video follows an unofficial clip of the bike with engine running.
