In terms of commercially available motorcycles, several manufacturers produce motorcycles with engine displacements in the range of 1,800cc to 2,500cc, such as the Harley-Davidson CVO Limited and the Triumph Rocket 3. These motorcycles have extremely powerful engines and offer exceptional performance, but they typically have engine displacements well below the 8.3-liter displacement of the Dodge Tomahawk.
It's important to note that the motorcycle industry is constantly evolving, and new models with larger engine displacements may be introduced in the future. Therefore, it's always a good idea to check the latest offerings from motorcycle manufacturers to get the most up-to-date information on the largest engine displacements available.
