I wasn't sure if you're kidding or serious.
Both 752S and Duke 790 are parallel twin. None are V-twin.
The firing order between two cylinders are:
752S - 360 degrees crankshaft, 360 degrees firing order. Means two pistons goes up and down at the same time, but left and right fire once after the other.
Duke 790 - crankshaft 285 separation, so firing order is: first - 285 - second - 435 - first... and so on. Means the first piston is leading the second piston by 285 degrees. This makes it sound like a V-twin with 75 degree block angle, with 360-degree crankshaft difference.
I feel the sound are not similar at all.
Benelli - very even... du du du du du du...
Duke - two - space - two - space... proom... proom... proom... very similar to true V-twin like Aprilia Shiver and Ducati. Even MT-07 sounds like 90 degree V-twin becoz of the 270 cross-plane crank.
I never said it is a v twin bro.
wht i meant was like you've explained, the crank angle and firing order makes it like a v - twin.
and no 752s is not 360.
it leans more towards the 790 configuration rather than the mt07 configuration.
