As a reference.
An MV Agusta F4 312R did it in 7:21.8 (so around a ~ 7:43.8)
There are a few stipulations though as since 1994, Bikes have been forbidden to do full lap sessions so the time is from the bridge to gantry. (where Top Gear's Jeremy Clarkson's "10 minutes" came from) So about 22 secs needs to be added to the lap.
