SureShift - the gear shift display with shift indicator
The advantages of gear shift displays for motorcycles, especially in motor sports, are well-known and no longer have to be highlighted.
In rally or touring cars, for example, large LED gear shift displays are often visible in the cockpit .
Many manufacturers of sport motorcycles now equip their models with a gear shift display at the factory.
By the same token, an adjustable shift indicator is a useful accessory, which is now finding its way from motor sport to the street motorcycle. It is used to determine the optimal gear shift speed or as a warning prior to the maximum allowable maximum engine speed. The SureShift from motogadget is a compact digital gear shift display combined with a two-stage shift indicator function.

The casing
The high-quality aluminum casing is milled from solid metal on CNC machines and its surface is bushed, anodised in black or high-gloss polished. The electronics are fully cast in the casing and thus protected from the weather, water, dust and vibration. Two threaded bushes on the reverse side easily mount the SureShift to any motorcycle.
The simple, neutral design and compact dimensions of only 33 mm in diameter and 14.5 mm in height make the SureShift an ideal accessory for any motorcycle.
The display
The LED display developed in-house represents an innovation in this area of application. It displays the digits normally or inversely (red surround/black figures) and has a clearly visible, two-stage shift indicator lamp at the same time.
The luminosity of the LEDs is automatically adjusted to achieve the best possible readability in darkness, sunlight and dusk.
The function
The SureShift is connected to the compatible electronic speedometer originally fitted to the vehicle or to an auxiliary speedometer (reed contact). An engine speed signal is also fed from the ignition box or ignition coil. It is then calibrated once in a learning procedure to the vehicle-specific gear ratio. It can then immediately determine the connected gear from the speed signal and engine speed. No mechanical switches or similar are required for errors in sensitive components.
An exact calibration of the speed is not required. The neutral position of the gearbox is read out in parallel to the neutral indicator light over the conventional neutral switch.
One engine speed value is programmed into the device for each of the two shift indicator stages.
Connection and compatibility
If the vehicle has a transistor ignition (negative firing pulse, 98% of all street bikes), the signal is compatible with the SureShift. The engine speed is then transferred direction from the ignition box or ignition coil. Should there be a capacitor ignition (CDI), an additional ignition signal pickup unit must be used.
For most motorcycles with an electronic tachometer, the tacho signal can for the most part be accepted by the original sensor. All sensors are compatible, which emit a signal/signal level of +5 V to +12 V. This includes Harley-Davidson™, Buell, Ducati, Aprilia, Suzuki Bandit (with electronic tacho) and others.
Should there be no electronic speedometer or there is not suitable signal, a complete speedometer kit can be ordered from us. It contains a very small reed contact (M5) with 150 cm connecting cable, two small neodymium magnets and an epoxy glue.
The device is normally programmed and set once after installation. If the gear transmission ratio is changed or the device is installed in a new vehicle, the settings must be made again. Entries in the form of a simple button signal must be made in part. For example, the gear lever or neutral switch can be used. If this is too circuitous , the included mini buttons or any other button can be temporarily connected. If the device is set correctly once, this button is no longer necessary for operation.
The simple wiring (5 connections: +12V, mass, tacho signal, engine speed signal, neutral switch) as well as the comprehensive installation and operating instructions also make connecting the instrument easy for users who have previously stayed away from the vehicle electronics.
Versions
The casings are available in the following versions: Black or high-gloss polish.
