The Dynojet Quick shifter allows full throttle, clutchless shifting. It does this by momentarily cutting the fuel and or ignition, which unloads the transmission. During this time, the rider can shift up to the next gear without rolling off the throttle or using the clutch. The Power Commander 3 USB incorporates all of the quick shifter functionality in with the main fuel controller and is fully programmable. The software provided allows the user to adjust the kill time as well as the minimum rpm level where the quick shifter will operate at (prevents the quick shifter working at low speeds, such as town riding etc).Note: Certain bikes require an ignition module to function.There are two basic types of quick shifter sensor: A Shift Rod pressure/tension sensor and a linear travel sensor.The Shift Rod sensor mounts inline with the shift rod and is available in both pressure (push) or tension (pull) styles, depending on the direction that the shift rod moves during an up shift.
