The numbers aren't up on the official site yet,
but there's a post on 'BentRider Online
indicating that Sam Whittingham had a run at 82.3 MPH or 132.45 KPH. This may be a new world record and I'll provide more details as they come to hand.
Which, even with strangedave
</lj> 's correction last time
a speeding ticket anywhere in Australia. :)
EDIT 22/09/2008: The numbers are now up: 82.33MPH or 132.50 KPH and marked as a new record pending approval. Congratulations to Sam Whittingham on a superb ride!
