200+ easily. I don't think they're speed limited, although mine is an EB Ghia. I'm just assuming that the ED donk/box have the same computer guts as the EB's. 6cyl EFs though are limited to 180, but I don't think they're rev limited coz I was doing single wheelers at around 5000rpm
I've forgotten what I think I got up to (speedo ends after 199), but it was either around 210 or 220, & it felt like I could squeeze maybe an extra 10kph out of her. Too bad I ran out of road :o
The wind noise was phenomenal!
