So please forgive me if it's an obvious answer. But why is the nose cone ram air intake really popular with 600's but not as much with 1000's?
I think its the same, all the bikes use ram air, 600's use a central air scoop 1000's use two sited each side
a lot of it has to do with the airbox position.but not all thou's have double intakes 04-07 blades,aprilla's,zx10's etc..
It's mostly aesthetics that dictates it, a 600 Is meant to be tiny, to have side inlets would make the fairing wider thus bigger.
