V8 engines are generally not common in motorcycles, as their design and size make them challenging to fit within the limited space available. V8 engines are larger and heavier compared to the more compact and lightweight engines commonly used in motorcycles.
While there may be rare and custom-built motorcycles that feature V8 engines, they are extremely rare and typically created as one-off or specialty projects. These custom motorcycles often have unique designs and are built by enthusiasts or custom bike builders who want to showcase engineering prowess or create something extraordinary.
It's worth noting that some motorcycles have utilized engines with a V-twin configuration, which resembles half of a V8 engine. V-twin engines are quite popular, particularly in cruiser-style motorcycles, due to their distinct sound, torque characteristics, and aesthetic appeal. However, they are still significantly different from full V8 engines in terms of size, complexity, and power output.
In summary, while V8 engines are not commonly found in production motorcycles, there may be extremely rare and custom-built motorcycles that feature them. However, the majority of motorcycles on the market use other engine configurations, such as single-cylinder, parallel-twin, inline-four, or V-twin designs.
