Doeas anybody know the differences between both models?

I asked Patrik personally and he said that the differences are " we improved the aerodynamics and its 8cm shooter, narrower nose with a round dome deck. the deck shape around the Footstrap area is also different. the rest is the same shape and it has the same bottom shape and cutouts.

cheers Aiden

thx for the answer.
What's the reason of the "in between" holes rows (placed just ahead of rear footstraps) of the V1 ?

I think that it is just for more inboard Footstrap holds
