In 1955 the Penya Motorista Barcelona called up for the first time the 24 Hours of Endurance of Montjuïc. Montesa won this race led by the team of Josep M Llobet Turuta and Joan Soler Bulto who rode a Brio 90 bike. The following year the triumph was also achieved by Montesa with the Elizalde Brothers in control of a Brio.
