The renewed Suzuka 4 Hours, restarting!
A class contested with 600cc supersport bikes. The modification range is strictly limited, making the conditions nearly equal, which leads to fierce competition among Riders.
As a foundation to accelerate the development of future young endurance Riders and vehicle development for the future, a new chapter of the Suzuka 4 Hours begins in 2026 alongside new classes (8H Challenge-Class, D-Class).
