The BF115's Dual Stage Induction offers a variable air intake manifold to deliver top performance at every speed. At low speeds, air passes through a long intake runner, increasing low-end torque. Above 3500RPM, shutter valves open to shorten the air’s path, boosting air flow for more high-end torque. The result is a simple, compact design that delivers the awesome performance for you - no matter how fast you want to go.
The engine's linear air/fuel and knock sensors help determine the correct fuel flow and ignition curve. They improve the overall engine operation and efficiency while preventing engine damage.
And a quick movement of the throttle control activates the BLAST™ system, advancing the ignition curve aggressively. 'Hole shot' is vastly improved as more horsepower gets the hull up on plane quicker.
