That's it exactly. Most of the bigger sport bikes don't see gains into triple-digit speeds, and since the 250 can barely attain that it's not worth it. Hell, I remember reading that the Buell 1125cr didn't utilize it's ram-air intakes until 150mph... But at that speed, it then became a pressurized air intake (and true ram air) adding to the bikes capabilities.AUDACIA said:even the 600's don't get any advantage until higher speeds tho.
