Information about the addition of a variation to the popular Honda GB350, which is still selling well, has been confirmed since the end of last year. Its appearance is still a veil of mystery, but we would like to summarize some of the rumors.
Derivative models are likely to debut in Japan in 2024.
The GB350/S was launched on July 6, 2023, complying with the 2020 emission regulations. In addition to these two models, a derivative model is expected to be introduced in 2024.
What kind of model this will be is unknown, but we would like to introduce three rumors that we have now. The new GB will be launched in Japan.
The most promising model is a derivative of the existing GB350 platform. This would be a means to attract new users by offering a new model while keeping costs down. For the sake of clarity, the editorial staff has created a CG of a GB400TT Mark 2 rocket cowl, but what do you think?
Furthermore, there are rumors of the existence of a new GB500. The old GB400 also had a GB500 with a larger displacement, and Yamaha once released the SR500. If there is room for a GB350 engine with a larger displacement, a new GB500 may be possible. The latest information seems to indicate that it will not appear.
In an oblique direction, the GB750 is also a candidate. The parallel two-cylinder engine newly developed for the XL750 Transalp and CB750 Hornet will be used in various models in the future, according to the development manager, and a classic-type model would be promising.
This is another derivative model!
