In 1913 the Model 65 was supplemented with the new 70, and also the 70A model, which were manufactured for two years. The Model 70 had a 405cc engine giving 3hp with a clutch in a pulley and as an option the customer could order a three-speed gear-hub in the rear wheel. The 70A had a slightly bigger engine with a 3.5hp output. By 1915 Moto-Rève had come up with an even bigger power unit. This time it was still a two-cylinder V-engine, but the Model 75 gave 3.5 or 4.5 horsepower, depending on choice. The stroke was 85mm for both versions, while bore was at 55 and 61 millimetres respectively. The smaller model – with a weight of just 80 kilograms - was priced at 1,300 Swedish Kronor (approx. 280 US dollars). The bigger one – weighing 90kg cost 1,400 SEK. By now, competition had entered people's mind and the bikes soon became popular for sport. This meant that many had a dual-purpose use, and the interest in competition grew fast among the purists.
