The 2023 factory Honda Suzuka 8 Hours team will consist of WorldSBK riders Xavi Vierge and Iker Lecuona, and four-time 8 Hours winner Takumi Takahashi.
Having skipped the 2022 Suzuka 8 Hours with its factory team, Yamaha will again rely on the YART World Endurance team for its 2023 8 Hours effort.
There will be no factory Kawasaki team at the 2023 Suzuka 8 Hours race, after the Akashi marque officially announced its absence from the event.
