Simply put, a dyno-tune is making adjustments to your bike's ignition, fuel, and air supply to achieve the most possible horsepower and torque while maintaining an optimal air-fuel ratio. To do this we use our state-of-the-art dynamometer (dyno). Before testing, your bike should be in good condition. If the tires, belt, etc. are in poor condition they may fail because they will be tested at maximum output.
