For what it's worth, my money [and I could be wrong] would be on a parallell twin. Reason being, this [should] be a 'clean sheet' design and the big twins of yestert
year were parallell jobs. If they take this route, I would like to see a 180 degree 800 cc or so c traditional twin. The 'Iron Barrel' has gone, as far as the factory is concearned, despite them being a major part of my bread and butter. Time to move on, for what comes off the line, but the 'Classic' jobs will still provide lots of scope for the home tuner and stock machine riders alike.
Harley and Ducati mass produce v twins for those who want them, already [among others], let's see what comes out of the factory doors next.

Hi BW,
I expect the RE factory to make theirs a parallel twin. It would fit in their frame, and they have the production ability to cast and manufacture those parts.
I like a parallel twin just fine myself, too
For us here, we are using the Bullet top ends on the V-Twin crankcases that Aniket is making, because that is more within our ability to do. Less castings to make.
Here's a pic of the crankcase castings and timing covers, prior to finish machining
(From the Kneeslider article).

This is a 59-degree V-Twin, with a common-crankpin, enlarged main bearing size, wet sump with cast-in windage tray, both oil pumps providing oil feed, solid lifters with 2 sets of Bullet cams, UCE filter element, pushrods adjusted under the rocker covers.
Has the shifter tunnel to allow left-shifting 5 speed if desired, or right-shifting 4-speed or 5-speed.
These will be the crankcases used for the ACE V-Twin 1070cc "Double Fireball".
