He said: "The speed at which you were travelling means a custodial sentence is the only option I have."
The court heard that Purves, who has since sold his Suzuki GSX-R 1000 motorbike, covered 0.7 of a mile in just 16 seconds on 13 May this year. His lawyer said he was "deeply ashamed" of the offence.
Procurator Fiscal Morag McLintock told a previous hearing: "We believe this is the highest speed that the police have ever recorded in Scotland. "A police speed check was taking place when officers were alerted by a high pitched whine from the motorcycle's engine." Last year more than 20 motorists were caught travelling at more than 100mph on the Dolphinton stretch of the A702. It has sparked calls for permanent speed cameras in the area.
