Tony Arnold, 50, admitted speeding on his Honda CBR 1000 at 6pm on August 21 but asked Skipton magistrates to take into account his job as a window cleaner.
Arnold, of Soutergate, Ulverston, told the court on Friday he had sold his motorbike and in the future intended to do his racing on tracks and not on roads.
He argued he would suffer exceptional hardship if he lost his licence as most of his customers, built up over 20 years, lived in the countryside and he would not be able to reach them.
Magistrates told Arnold, who already had six points on his licence, that it was a very high speed on a road which they believed was used by drivers as a racetrack.
They turned down his exceptional hardship argument and endorsed his licence with six penalty points, taking him to the maximum 12 and giving him an automatic six month ban.
He was also fined £155 with costs of £85 and a victims surcharge of £20.
