HiThe large capacity(cc) is a trend in the newer sports bikes.I think it is just a horsepower war in the go faster crowd.Jeri
Beans. Different kinds of beans, chili, lots of cumin and spices, onions and fatback, oil and veinegar- still beans. Ever wonder why these bikes keep getting bigger, but not faster? Because the average motorcycle consumer is stupid as a bean. Weather it's a Harley or a Star- these bikes should be capable of twice the speed.
I think the power requirement for overcoming air resistance goes up with the square of the speed. So you would need close on 200 hp for 200 mph, i.e. four times the amount needed to reach 100 mphAlso, there are horses and horses! Some of the horses in 1980s Japanese bikes were definitely on the coltish side of full grown. They would tell you there were 67 of them - or whatever - but your motorcycle would be no faster than a Bonneville with 50 British ones.
