The last precedents in the other classes
However, the pairings in the other classes are much more frequent as can be seen from this ranking ,which starting with the most recent and working backwards retraces, for each category, the last time a rider and a bike from the same country won the World Championship.
Moto3: Izan Guevara and GasGas (Spain, 2022)
In his second year in the World Championship, the Spaniard earned the title in the lowest class with 7 wins and 12 podiums with the Aspar team GasGas. And yet after the first 4 races he was only 4th with half of the points that Dennis Foggia had but then he moved into top gear and became a champion when he was 18 years and 110 days old.
Moto2: Stefan Bradl and Kalex (Germany, 2011)
In 2010 Moto2 replaced the 250 class: Toni Elias won with Moriwaki. But in the following season, Kalex showed that it was better. The first rider to win the World Championship with the German manufacturer was Stefan Bradl in 2011, also thanks to the physical problems that stopped Marc Marquez from competing in the last two GPs.
125: Marc Marquez and Derbi (Spain, 2010)
Twelve years ago Marc Marquez began building his legend riding a Derbi RSA 125 prepared by the Ajo Motorsport team. Starting with Mugello he won 5 GPs in a row, then won another 5 and overtook Nicolas Terol to win the first of his 8 World Championships.
250: Hiroshi Aoyama and Honda (Japan, 2009)
Japan hasn’t won a world title since 2009 when Hiroshi Aoyama got the better of a string of Aprilias and Gileras thanks to his impressively consistent performance: he finished all 16 GPs in the top 8 positions assisted by the Scot Racing Team's Honda.
80: Manuel Herreros and Derbi (Spain, 1989)
For 6 seasons, from 1984 to 1989, the World Championship had a fourth class, the 80 one. The last world champion in this category was Manuel Herreros, although he didn’t get any outright wins: with Derbi he achieved 4 second places, 1 fourth and 1 fifth out of 6 races, ahead of Krauser who won 5 GPs.
50: Ricardo Tormo and Bultaco (Spain, 1981)
Ricardo Tormo is the name that the Valencia circuit is known by and is a tribute to the local rider who lost his battle with leukemia in 1998. Tormo was twice world champion once again in the 50 class with Bultaco. The last time was in 1981 with 6 wins in 8 races.
