The small category of the World Cup

The category currently known as Moto3 has its origins in 1949, when the International Motorcycle Federation (FIM) organized the first Grand Prix (GP). The small category, then, was the 125cc, known among fans as the eighth of a liter. In 1962 another even smaller category was added, the 50cc, which would be part of the Grand Prix until 1983. Replaced since 1984 by the 80cc and disappeared in 1989.

During the beginnings of 125cc, in a similar way to what happened in 250cc, 4-stroke motorcycles dominated, but in the mid-1960s the 2-stroke engines were gaining ground until it was shown that in equal displacement they achieved greater performance.

The 125cc class is the only one that remained from 1949 until it was replaced by Moto3 in 2012. Then the small class followed the path set by MotoGP and Moto2, back to 4-stroke but with 250cc single-cylinder engines, double than 125cc 2-stroke bikes. Unlike the Moto2 category, where there is a single supplier of propellants for everyone, Moto3 is open to all the factories that want to participate, with a maximum cost per engine of € 12,000. Currently Honda and KTM dominate the grid.

During 2012, the regulations already required the use of the new propellants. Seeing the experience of what was lived in MotoGP and later in Moto2, with a regulation that favored 4-stroke motorcycles, everyone bet on the future with a wide variety of brands. The difference in cubic centimeters of the engine would make a difference, with the 125cc motorcycles disappearing at the end of 2011. The technological development was directed towards the 4-stroke engines, more efficient and less polluting. The competition could not go against him and this was the main reason for the change.
