Suzuki will return to the Suzuka 8 Hours endurance race this August 1-3, continuing their carbon-neutral racing project and hoping to improve on their eighth-place result from last year. The Suzuki CN Challenge team will field an upgraded GSX-R1000R with more planet-friendly tech, including 100% sustainable fuel and aerodynamic wings that could hint at future developments in road bikes.
The GSX-R1000R will once again compete in the Experimental Class, where Suzuki has replaced the 40% bio-sourced petrol used last year with a 100% sustainable blend from TotalEnergies. This is a major step towards the goal of MotoGP replicating this fuel mix by 2027.
The base 199bhp machine is found in the endurance racer with full superbike trim, including upgraded parts for the chassis, suspension, brakes, and swingarm. It is once again led by Shinichi Sahara, the former MotoGP team boss, and ex-Suzuki MotoGP rider Takuya Tsuda will return to lead the rider seat.
According to Toshihiro Suzuki, the president of Suzuki, “Although it was a new challenge for the company last year, thanks to the support of partner companies, such as Yoshimura Japan, and the enthusiasm of the fans, we achieved eighth place.” He added, “We will continue to participate this year to showcase technology development in the sustainability field.”
The GSX-R1000R includes carbon bodywork that is recyclable, fenders made from flax, and an inline-four motor that will use bio-based oil from Motul. Also introduced in 2025 are front aero wings, which were absent last year, so this could indicate ongoing development behind the scenes. Bridgestone will supply tires with a higher proportion of recycled materials compared to last year.
In addition, Yoshimura will provide a full-system exhaust with a catalytic converter to reduce some emissions, and made of eco-friendly titanium called TranTixxii. The brake pads are designed to reduce dust, and the team uniforms are made from 100% recycled fabric.
Tsuyoshi Tanaka, Executive General Manager of Motorcycle Operations, expects, “Last year, we took an important step towards the future of internal combustion and motorsports. This year, we will expand the use of sustainable items and continue to conduct technology development.”
This race will serve as the 46th running of the Suzuka 8 Hours and part of the 2025 FIM Endurance World Championship (EWC).
