A couple of times I've pulled the bike back at an indicated 175kph - the bike had more in it but I didn't. 790cc, 18/43, slightly bigger than standard jets (can't remember what size, not much over standard though), modified air inlet, thunderbike pipes. Oh, and a big roadster screen to slow it down too, so would probably do more without it. Before the pipes it would max out at just over an indicated 160kph.
