3S SOT secured the First Bikers Weekend Dupnitsa, which took place on 8th and 9th of July 2011, at Krainitsi Airport. The weekend was organised by the Motor Sports Club Biker Bpoys. The idea of the organizers is to transform it into an yearly event.

The programme was extremely dinamic, including Honorary Bikers Tour of the town of Dupnitsa, marked segments and attractive biking, beer keg's rolling, and Fireball band performance.

3S SOT provided for free the teams of professional guards for the two days of the Bikers weekend to ensure the peace and security of participants and spectators.
