The end of a long history
Last 4 Hours!
The JP250 class, which began in the 2016 season, is contested with production-based machines.
In addition to reasonable vehicle prices, the class is gaining attention for its close battles from the race start to the checkered flag, thanks to the equal conditions provided by the Dunlop tire one-make.
From 2017, the 4-hour endurance race in this JP250 has started, and despite being a lightweight class, it has become the gateway to the Suzuka Endurance Race.
The ST600 is a 600cc super sports bike race, with Bridgestone tires being the one make. Due to strict limitations on modifications, it is the category closest to production vehicles.
It is a popular class where riders fiercely compete with each other in conditions close to equal, and the Suzuka 4 Hours Endurance Road Race is a 4-hour battle between two classes, ST600 (Inter/National) running together.
There is a long history of producing many riders who have excelled in dramas and 8-hour races in the Suzuka 4 Hours , which has been held since 1980.
