We continue to build our cafe racer based on K1100LT
Electric is a final stage before painting
We made new electric system with digital Motogadget components
The aim was to hide wires and provide the necessary functionality
Compact battery from yamaha R6 is under the tail fairing
It’s mounted on rubber inserts to damper vibrations
Here are OEM starter relay and rectifier regulator
Wire to M-Unit, generator, starter go to +
Wire to regulator, frame, engine, starter go to —
We don’t combine wires to one clamp, because we’d like to have fully demountable system
M-Unit is located in front, under the tank
It’s mounted on two pins and touches the frame
Watch detailed review of M-Unit at our channel
M-unit is connected to battery via main fuze (60A)
We use contact free RFID ignition lock, so there is no standard key lock at our bike
Optics are operated by push button controls
Turn signals are operated by lower buttons on left and right switch control
Hazard is turned on by simultaneous pressing both turn signal buttons
All rear lights are connected with water resistant connector
Low beam are turned on by upper button on the left control switch
Low beam is switched to Hi beam by pressing with delay
Gauge has corresponding indicators
Horn is on the front button of left switch
Starter and kill-switch is on the upper button of right switch control
Front button of right switch control operates gauge’s navigation
Switch controls and front brake sensor are connected to M-Button Relay
M-Button allows to hide all connectors in headlight body and connect only one wire to M-Unit (Config port)
Rear brake sensors is integrated in banjo bolt and goes to M-Unit (Brake port)
All operations are duplicated with led lights on M-Unit
Motronic wire was cut
There is water resistant M-Relay to control radiator fan on the right side of M-Unit
There is water resistant M-Relay to control fuel pump on the left side of M-Unit
Both relays are controlled by Motronic
K1100LT has gear counter with three operating wires and ground
Neutral coincides the case, when all operating wires are connected to the ground
So we made simple circuit with two relays connected successively
Oil pressure light is on the right of neutral light
It goes to oil pressure sensor in the engine
Other lights are located on Motoscope Mini panel
Blue one is charging alarm and it goes to generator
Green one is low fuel level alarm and it goes to sensor in fuel tank
Red one is temperature alarm and it goes to temperature switch in the engine
We use temperature switch (100 C) instead of OEM temperature sensor
OEM speed sensor does not fit Motogadget gauge, so we made alloy cap instead
We use motogadget speed sensor with magnets
It’s mounted on the OEM wire clamp
One wire goes to gauge, another one goes to the ground
Responding magnet is mounted on the self made bracket in place of ABS rotor bolt
Solution is reliable, provides required distance and hidden from view
Gauge should be teach on the road or you can set wheel parameters to get accurate speedometer
We will cut wires one more time at final assembly and install protective sleeves
Frame will be modified for better wiring
Number of connectors can be reduced, but we prefer to have fully demountable system
Motogadget components significantly reduced the size and weight of electric system
They are water and vibration resistant
OEM electric with gauge, relays, ignition lock, switch controls, units and wires weighs 9kg
With OEM batter it weighs 17kg
It’s impossible to hide all this under the tail and tank
Visible installation spoils the design and image of the cafe racer
