KTM Racing obviously have some sense of humour and use well-known PR tricks.
FMX4ever meets KTM Racing:
Goes to show there has been interaction between FMX and KTM Racing.
Given the camera resources available - at KTM Racing will etc. - it's a bit strange they don't show some actual footage of Coma doing those stunts.
To me it simply looks like they either manipulated the photo's or dressed up a pro FMX rider in Coma apparel and did the shooting on a 450 Rally with appropriately little fuel in the tanks..
In these days of well-known film-tricks a sceptical and critical audience won't be easily fooled.
