  • What is a Dyno Tune?

    Simply put, a Dyno Tune makes adjustments to your motorcycle ignition, fuel, and air supply to maximize horsepower and torque while maintaining optimal air-fuel ratio. To acheive this, we use our state of the art Dynamometer (Dyno). Before testing, your motorcycle should be in good condition. If the tires, belt, etc. are in poor condition, they may fail, since the Dyno tests your motorcycle at maximum output. The Dyno at St. Charles Harley-Davidson® is able to handle Trikes too!
