In addition to their suitability for racing, in terms of power-to-weight, Ossa motorcycles soon gained a reputation for reliability on and off the track. Despite this growing enthusiasm for the beautifully crafted and rugged bikes themselves, the firm suffered from a disorganized and sparse dealer network in the important American market. Ossa hired British rider Mick Andrews to help design and ride their trials bike, and they went on to capture the 19 European Trials Championship, the forerunner to the FIM World Championship. Andrews won the grueling Scottish Six Days Trial three consecutive years between 19 for the Ossa factory. However, Ossa redirected their competitive efforts into the sport of Observed Trials in Europe and the United States alongside such other famous Spanish makes as Bultaco and Montesa. They achieved some success in the AMA Grand National Championship, with rider Dick Mann helping them develop a 250cc dirt track bike on which he won the 1969 Santa Fe Grand National short track event, held on a quarter-mile dirt track oval. They also achieved early success in Grand Prix road racing, competing with an innovative monocoque-framed bike designed by Giró’s son, Eduardo and ridden by Santiago Herrero. Herrero won four 250 cc Grands Prix with Ossa before he died while competing at the 1970 Isle of Man TT. The loss of their star rider affected the Ossa team so much that they withdrew from road racing altogether.

Against all the major Spanish factories, Ossa motorcycles finished a surprising first and second.Inspired by this success, the factory decided to compete abroad in order to make inroads into the international market. Their first success came at the 1967 24 Hours of Montjuich on the streets of Barcelona. The Ossa firm was a strong supporter of all forms of motorcycle sport including: road racing, motocross, enduro and observed trials. In the United States and Canada, off-road motorcycling – and particularly the newly imported sport of motocross to which the light-weight and powerful Ossa was well suited – enjoyed a surging popularity. The original Ossa company got its start in 1924 making movie projectors for its home market in Spain. After World War II, Ossa, like several other manufacturers from BSA to Harley-Davidson to Yamaha, began producing two-stroke engined motorcycles, with their first mass produced model being introduced in 1949. Ossa reached its highest production levels in the motorcycle boom of the 1960s, exporting large numbers of exports to other European countries, but also significantly, to North American markets.
