No, fuel-injected motorcycles do not typically have a choke. The purpose of a choke is to restrict the air supply to the engine to create a richer fuel-to-air mixture during cold starts or when the engine is not warmed up. This helps in achieving a stable idle and smooth running until the engine reaches its optimal operating temperature.
In fuel-injected motorcycles, the engine's air-fuel mixture is controlled by the electronic fuel injection system. The fuel injectors precisely regulate the amount of fuel injected into the combustion chamber based on various engine parameters such as temperature, throttle position, and engine speed. This system automatically adjusts the air-fuel mixture to provide the optimal ratio for starting, running, and acceleration under various conditions, including cold starts.
Instead of a choke, fuel-injected motorcycles may have other mechanisms or technologies in place to assist with cold starts. For example, some motorcycles may feature an idle speed control system that automatically adjusts the engine's idle speed during cold start conditions. Additionally, the electronic control unit (ECU) of the fuel injection system may provide extra fuel during startup to compensate for the colder engine temperature.
It's important to note that while fuel injection has become the standard technology for modern motorcycles, there may still be some older models or specialized motorcycles that use a carburetor system with a choke.
