Many people confuse themselves as the higher the cc of a bike, the higher the speed. This is perhaps a wrong conception, as apart from the engine displacement, many other factors decide the speed. The higher the cc, the more power a motorcycle can generate, which leads to more fuel consumption. So before you jump in to know which is the highest cc bike? Let me break the question into three parts:
- Production Motorcycles: These motorcycles are globally approved by the government authority, which then go under mass production for the public to buy & own.
- Custom Motorcycles: Custom bikes are only built once or a couple of units by the owner or a team. It is never available to the general public and does not go for production.
- Road Legal: Road-legal motorcycles are also approved by the government. These motorcycles use custom engines derived from an aircraft or a supercar.
The road-legal highest cc bike is the BOSS HOSS which holds a massive 6200cc engine. The V8 engine of the bike is derived from Chevrolet and is globally approved for production. Talking about pure production motorcycles, the Triumph Rocket III with a 2500cc inline 3 engine is the highest cc production motorcycle. And if you consider custom bikes, the Dodge Tomahawk holds a humongous 8300cc viper engine which is the highest cc custom bike.

DODGE TOMAHAWK
I have compiled a list of the top 10 highest cc bikes globally, which are available for the general public to buy and own. These bikes are globally approved and legal on the streets. Please note that custom bikes such as the Dodge Tomahawk are excluded from the list.
