The Uganda Revenue Authority has given cyclists with Kenyan registered motorcycles one week to register them in Uganda or else they will be impounded.
The authority said the cycles pose a security threat especially in the border areas of Busia, Malaba and Tororo.
John Malinzi, the URA customs manager Eastern Uganda said many of the owners of the motorcycles are not known.
But some of the riders said they register their motorcycles in Kenya because it is cheaper to register a motorbike in Kenya than Uganda.
The riders said motorcycles in Kenya are sold at Shs 3.8 million compared to Uganda where the figure is Shs 4.4 million.
They urged URA to instead reduce the taxes on motorbikes.
Malinzi said the cyclists allegation of motorcycles being cheap in Kenya compared to Uganda was not realistic.
“We have given them up to the end of the week to register them in Uganda. We shall not hesitate to impound them,” he said.
