Years ago, when I was looking to buy an Audi, out of the 10'ish I looked at I would say 7 or 8 of them had been clocked.

Now I'm looking for a 650cc bike & the mileage varies from 100 mile per year upward, I know nothing about bikes,but with digital clocks,it must be easy to clock them, even if its every year before the MOT

How common is it? & do you have any tips?

Thanks
