That's ok then beeps.
The risk of being stopped for anything like this is near to zero anyway, so no need to hide in the bike shed.
The problem might arise at some time in the future when there's been a fatality and the police decide to do their full scale thorough accident investigation. An overweight bike subsequently found to overperform as well could open a whole can of worms, especially if only supplied through ebay direct from outside the European law area.
That could trigger action of a more widespread nature by all forces.
