And why would that be?

Chains are a relict of shitty end user technology, just because they are cheap, halfway light, and transfer power pretty efficiently. That doesn't make them "the best drive". It just makes them not go away, which they should have 30 years ago for normal street motorcycles outside the Race Replica and the < 500cc class. A standard swingarm with a shaft isn't that much heavier or more expensive than a swingarm with a chain, you don't loose much power (And who the hell cares for the 2 or 3 HP outside the race track?) and the convenience is just unbelievable compared to a chain.
Just my 2c of course ...
