The All Japan Road Race Championship (Japanese: 全日本ロードレース選手権, Hepburn: Zen Nihon Rōdo Rēsu Senshuken) is the premiere motorcycle road racing championship in Japan. It is run by the Motorcycle Federation of Japan (MFJ) (日本モーターサイクルスポーツ協会) – the Japanese affiliate of the FIM.
History
The MFJ was formed in 1961 and held its first motorcycle road race in 1967.[1][2][3]
The Championship's premiere class for a number of years had been the 500cc class but it was replaced by a superbike class in 1994. During the 2002 season the championship was used by some manufacturers to test their MotoGP prototypes. The prototypes usually won the races but were not eligible for points. The series now runs a small seven round schedule but has a large field of Japanese riders and bikes. Similar to Spain's CEV championship, Moto3 motorcycles are used in Japan.
Current classes
JSB1000
The motorcycles used are primarily based on 1000cc commercial road sport models, modified into full race-spec machines. Since the 2023 season, the class has been using the carbon-neutral racing fuel ETS Renewa Blaze NIHON R100. The manufacturers usually involved are Honda, Kawasaki, Suzuki, Yamaha, Aprilia, BMW and Ducati. They use specs similar to those used in the Endurance World Championship, the top category of the Suzuka 8 Hours endurance race and the Superbike World Championship.[4][5]
Tyre suppliers vary from Dunlop to Bridgestone.[6][7]
ST1000
Like in the JSB1000, the motorcycles are based on commercially available road sport models with 1000cc engines, but the range of modifications allowed for racing is extremely limited, making them much closer to stock. The manufacturers involved are the same ones from JSB1000. The machines align with the SST class regulations used in the Suzuka 8 Hours endurance race, which is part of the Endurance World Championship.[4][8]
All teams use series-specified Dunlop tyres.[6]
ST600
The motorcycles used are primarily based on 600cc commercial road sport models. Like in ST1000, the range of modifications allowed for racing use is very limited. Honda and Yamaha are the main manufacturers in the class.[4][9]
All teams use series-specified Bridgestone tyres.[7]
J-GP3
The motorcycles used are prototype-based machines, the Honda NSF250R and KTM RC250R. The machines conform to the specifications of the Moto3™ class in the MotoGP™ World Championship.[4][10]
Tyre suppliers vary from Dunlop, Bridgestone and Pirelli.[6][7]
