The exhaust pipes, which emitted noise louder than the legal limit, and the illegally modified motorcycles had been seized by Mueang Loei police since June 1 last year as part of measures to crack down on road racing.
Mueang Loei police chief Pol Colonel Torsak Aranyakanon chaired the ceremony in which a road roller was used to crush the pipes and motorcycles in front of the police station at 11am.
