David Alonso led Moto3 World Championship Practice One (P1) Friday afternoon at Circuit de Barcelona-Catalunya, in Spain. On board his Gaviota Aspar Team CFMOTO fitted with Pirelli control tires, the Colombian lapped the 2.9-mile (4.7 km) course in 1:46.897. That was enough to top the 27-rider field, but it was slightly slower than the new All-Time Lap Record of 1:46.838 he set Friday morning.
