Lots of bikes will top 200 mph if they aren't restricted by law, which to my mind is crazy.
Bikes in the UK must be restricted to186mph (300km/h) If I was crazy enough to try this on a road or track (and I definately don't reccomend any British roads) then if it did go tits up I reckon I would end up as roadkill wether I was doing 180 or just that little bit higher .
If you really want to fly I reccomend the nearest racetrack..
