Default Why is the 270° crank so popular?

... and why is it still the wrong angle?

I watched that one the other day - his blackboard explanations make so much sense, although some of his techie bits go slightly over my head...

The bit about twins having way less ring area for unburnt fuel to hide in making their stats much better than a four was very interesting.

A more technical explanation on why Fortnine was wrong (or not totally correct). A 285° parallel twin does not have better balance than a 270°.
