Revealed patent suggests Honda CBR250R’s 4-cylinder engine

24 Aug 2021

A series of images of Honda’s new 4-cylinder engine block patent has just been shared by the media with high hopes for a new Honda CB250R model to compete with Kawasaki ZX-25R.

In the current motorcycle market race, Kawasaki is leading in the small-sized Sportbike segment with the Kawasaki ZX-25R model owning a powerful howling 4-cylinder engine. From which, many rumors around the world for competitors such as Honda or Yamaha, Suzuki will launch new models to compete.

Recently, a website about motorcycles in Japan has just revealed a new Honda patent with a 4-cylinder engine block that many people think is the engine block to compete against the ZX-25R.

Accordingly, the two images shared are the basic design and structure of the new engine block. With the bullhead and cylinder height design, it can be speculated that this is a modern engine block with DOHC form and has a rather short cylinder height. This proves that Honda’s new engine block will have the ability to function at very high RPMs, and this is often found in modern Sportbike models.

Currently, Honda’s smallest 4-cylinder model still on the market is the Honda CB400SF – this is a legendary and iconic model of the Japanese automaker. However, if you compare this engine block with the aforementioned designs, there are many differences. In the shared images, piston size and cylinder diameter are undisclosed. Hence, the capacity of the engine block remains unknown. Therefore, all information up to now is still only at the level of speculation.
