NOTE :: This unit DOES NOT have an included Gear Display.

A Gear Emulator or sometimes called a "ATRE" or "Automatic Timing Retard Eliminator", is a product that simply tells the motorcycle's computer that the motorcycle is in a specified gear overriding the current gear. On some Suzuki models, a "motor timing retard" may be applied at the factory in certain gears. Some Suzuki models, such as earlier model (01-03) SV1000s would have a slight stumble when applying acceleration. This helps alleviate that issue. Many M109 riders have reported better part-throttle response and increased fuel mileage.

The Gear Emulator is a simple transistor based product. Since the Suzuki Gear Position Sensor is based off of a varying voltage system, we simply bypass the Gear Position Sensor and tell the motorcycle that we are in a specified gear all the time. The "automatic" or "smart" part of the Gear Emulator (TRE) is the transistor that only activates the bypass when the motorcycle is not in NEUTRAL. This is important because we don't want to affect the motor timing at "idle".

Switchable units are available from certain manufacturers, but there is really no need for this option - assuming you're buying a transistor based product.

Cheap designs that only include a single resistor should be avoided since they change the mapping of NEUTRAL which can affect your starting.

We don't recommend splicing a resistor into your motorcycle's harness for a couple reasons. If you don't have the right equipment to do such a job, you can easily ground out the circuit and end up burning up your ECU. Secondly, when the next owner of your bike does an inspection and sees cut wires, then the value of your bike drops dramatically. Lastly, a resistor will affect your motorcycle's starting, especially in colder weather. Look for a Gear Emulator with the features described above.
