Just a quick link for those of you that have derestricted your bikes early and think no one will ever know.
It's an operation by Avon and Somerset police called operation torque, where they have been stopping bikes and testing them at the roadside for there power output and making sure the rider is licensed to ride the bike they are on.
I should image other forces may be capable of doing the same.
