A Ministry of Defence chauffeur faces losing his job after his Yamaha motorbike was clocked speeding at 125mph in the Borders.
Philip Gower, 41, who has driven foreign dignitaries including the King of Tonga on official business in Scotland, received a nine-month ban.
Gower of Kirknewton, West Lothian, was caught speeding along with a friend on the Dolphinton Straight last October.
Steven McIntyre, 30, was clocked at 135mph on his Honda 600cc bike.
McIntyre, of Tillicoultry, Clackmannanshire, was banned for 12 months but unlike Gower is set to keep his job, Peebles Sheriff Court was told.
The Crown accepted not guilty pleas from both men to driving dangerously by racing their machines on the A702 Edinburgh to Biggar road.
The court was told Gower, who chauffeurs military officials around the country, was likely to lose his job because of the offence.
Defence lawyer Mark Harrower said: "He is a first-class driver and is well thought of. He has never blotted his copybook during his working hours."
However, the court heard that McIntyre, who is a serving firefighter, would keep his job.
As well as their periods of disqualification, both men were each fined £450.
The Dolphinton Straight hit the headlines last year when a Berwickshire hairdresser was jailed for nine months for hitting the highest recorded road speed in Scotland at 166mph.
