How It Works
Rapid Bike Revolution in Lambda Sensor Management
The introduction of electronics in motorcycle engines made it necessary to use sensors to monitor and modify the amount of fuel injected to ensure correct combustion.
The quantity and quality of air drawn into the engine and mixed with fuel are directly affected by external factors such as temperature, atmospheric pressure, and humidity, which can significantly impact performance and riding pleasure.
