I think its overkill, because its an engine as big as many cars, on a bike for just one person.
I'm one of those people, who want a regular engine, that is tuned and optimised instead of just having bigger bore.
And yeah i know, that a ferrari engine is always optimised, but i still think its overkill, as it will never get to strech its legs, as noone will ever use it fully. Like if The Hulk were to get a normal job... He and his big muscles should be put to use.
