- Rumoured to be unveiled in China on Sep 19
- Expected to be ground-up models
- No word about global launch yet
Following the recent unveiling of the Honda CB1000F and CB1000F SE as successors to the famed CB1300 Super Four and Super Bol d’Or, speculation is mounting that Honda may be preparing a smaller four-cylinder retro model to replace the CB400SF, which was discontinued in 2022. Recent reports now suggest that this new machine could make its debut at the CIMAMotor show in China on September 19.
These rumours have a solid basis. Honda is actively developing a fully-faired, four-cylinder sportbike aimed at competing with rivals such as the Kawasaki Ninja ZX-4RR, and a growing lineup of Chinese-made models like CFMoto’s 500SR Voom. In 2023, Honda filed trademarks for CBR500R Four and CBR400R Four across multiple regions. The 400cc variant is expected to target markets with licensing restrictions like Japan, while the 500cc version is likely to be available globally.
Given that the platform is already in development, transitioning to a naked version, branded as the CB500 Super Four or CB400 Super Four, seems like a natural progression. Supporting this, Honda recently filed for trademark protection in Japan under the name “CB400 Super Four,” suggesting that such a model is forthcoming.
On the technology front, the new engine powering the CB500 Super Four and CBR500R is believed to be an all-new design rather than an evolution of the CB400SF’s motor. It may also feature Honda’s E-Clutch system, already seen on the CB650R and CBR650R, potentially as standard or optional equipment.
The global demand for bikes in the 400cc to 500cc segment is growing rapidly. Younger riders in emerging markets, especially in China, are seeking upgrades from smaller displacement motorcycles, while in regions like Europe, older enthusiasts are downsizing from heavyweight bikes to more accessible midsize alternatives.
Industry sources indicate that the CB500 Super Four for the Chinese market will likely be produced by Honda’s Wuyang-Honda joint venture, helping reduce costs and remain competitive against local brands. However, given Honda’s extensive global manufacturing network, the bike could also be assembled in other regions depending on tariffs and trade policies. Meanwhile, the Japanese-market CB400 Super Four is expected to be produced in Japan.
