The motoscope mini is a highly compact digital instrument for motorbikes.
The LED display we created for the motoscope mini is unique in the instrument realm. 251 ultra-bright LEDs provide an essentially rimless and extremely readable display surface that can entirely be used for the display of readings. This intricate and innovative technology combines a maximum of display surface with minimal casing dimensions.
The unadorned and elegant design of the motoscope mini and its high-class appearance fit every bike, trike, or four-wheel vehicle. Exposed mounting can reinforce style and looks, but it might just as well be installed more discretely and 'clean' - with the mini, everything is possible!
Casing
The high-quality aluminum casing is machined from solid metal and its surface is black anodized. The mirror-polished variant has its own appeal. Electronics come completely moulded-in and are immune to weather, water, dust, and vibrations.
Display and features
The innovative, ultra-bright 251-LED dot matrix shows the engine speed in a scalable horizontal bar graph and all other features as easily readable numeric values. With the push of a button, the engine speed can be displayed as a numerical value (rpm) as well.
For optimal readability in dark, sunlight and dawn conditions, the LED luminosity varies automatically.
Specific engine speed thresholds can be programmed for the display to show the maximum permissible engine speed ('red zone') or a gear shift light with all LEDs pulsating simultaneously.
The kicker: The display of the motoscope mini not only displays numeric values from left to right but from top to bottom as well. Thus, the instrument may also be mounted vertically!
Operation
You can toggle between the different information on the LED display by operating the provided menu push-button or e.g. the headlight flasher push-button on the handlebar.
By default, the display shows the speed value. Other values may be displayed via push-button operation if needed. A feature for automatically switching back to the speed value after a predetermined time or leaving the manually chosen value on the display is provided.
Default settings or recorded values are of course stored even with the power supply switched off.
Mounting
Due to its compact dimensions, the motoscope mini is easily mounted just about anywhere on any vehicle. Single mount on your triple clamp or right onto the handle bar, embedded into already present instrument panels, into the tank, or FBE - this instrument is applicable anywhere.
We offer universal mounts as well as brand-specific solutions e.g. for Buell or Harley-Davidson. Please refer to 'Mounting'.
Connection and sensors
Hassle-free wiring and detailed installation and operating instructions enable even users without any previous experience in handling the vehicle's electrical system to connect this instrument.
The supplied speedometer sensor in stainless steel is very small (M5/25 mm). The 1.5 m connector cable easily connects it to the front or back wheel. This permits easy conversions of originally mechanical speedometer drives.
The motoscope mini is compatible with various original speedometer sensors (reed contact and proximity sensors) used by motorbike manufacturers. In these cases, only the terminals have to be connected while the installation of mechanical sensors will be completely obsolete.
An intelligent 'teaching' function provides for easy speedometer calibration - even in cases of vehicles with sensors at the gearbox.

Motogadget m.switch 3 button
Regular price
$157.00
m.switch 3 button
PLEASE NOTE: m.switch 22mm black with 2 and 3 buttons black - ABOUT 6 - 8 WEEKS DELIVERY TIME
New: Now also with 3 push-buttons per unit.
The m.switch is a high-quality universal push-button control for handlebars with 1 in. or 22 mm (7/8 in.) tube diameter in a plain and elegant design.
These finely CNC machined hand controls in combination with an electronic push-button control unit (not included in kit) are used to operate all electrical features, e.g. lights, turn signal, E-Starter, horn, etc.
The casing is made from CNC machined billet aluminum and is available in mirror polished or reflective black finished surfaces respectively. The compact design casing permits mounting two or more units on one handle bar.
Each unit is equipped with two or three push buttons in black or stainless steel. Different looks matching or contrasting the casing can be combined freely. Two flush built-in M5 stainless steel mounting screws (only one screw on the three-button version) ensure secure and stable clamping of the push-button control to all handle bars.
The push-buttons are of high quality, very robust design and vibration- and spray water-proof (IP65). The adequate size and ergonomic pressure point (easy, mechanical detent) provide for a definite actuation sensing - even when operated with gloves. This feedback allows shifting without the need to check the operation.
Each push-button is equipped with two terminals for an easy optional circuit layout with only one or two cables. The internal ground terminal is already provided for the 'one cable layout'. Therefore, the routing of the cable inside the handle bar can be performed easily.
The push-buttons are available separately and can be replaced if damaged. The m.switch is of course compatible to all common push-button controls, e.g. the m-Unit.

Motogadget mo.blaze disc dark
Regular price
$174.95
mo.blaze disc dark
Discover the dark side - a tinted look makes the mo.blaze disc disappear on the handlebars and emits light from all sides. An innovative top product, handmade in Berlin. The design and high-quality appearance make the mo.blaze disc a highly regarded design classic.
For use as a pair, please order one left and one right turn signal.
The mo.blaze disc is the flashing signal light of the latest generation. The characteristic feature of the LED turn signal is the transparent illuminated disc on a compact aluminum base, which harmoniously closes with the handlebar end grip.
This is motogadget's third turn signal, which uses the new TranzLight technology (TLT, patent pending). This progressive development approach is not limited to simple miniaturization of turn signal housings, but designs the light directly via a crystal-like plastic body. Only precise optical CAD calculations and state-of-the-art manufacturing processes make this novel design and its function possible.
The light flux required for the TranzLight principle is generated by the motogadget's intensiLED® process and consists of three important components three important components:
Selected high-performance LEDs with maximum efficiency and a total output of 9W with a service life of more than 50,000 hours
An IC-controlled constant current regulation clocked at 330kHz
A special collimator optic that couples the light from the LED precisely into the plastic body
The discreet aluminum housing is only used for the stable mounting of the glass body and the integration of control electronics and high-end LEDs. Of course, the housing is CNC-manufactured, black anodized or highly polished and finely inscribed by laser.
The handlebar end turn signal builds very flat and appears through the transparent disc neutral and inconspicuous. Thus, it fits many styles and the most diverse motorcycles. The flasher can be operated like any other LED flasher with load resistors or all our load-independent flasher relays (mo.flash, mo.wave, mo.stop, mo.relay+).
The handlebar end blinker mo.blaze disc presented here has an E-mark and is ECE-approved as a front blinker.
