•It’s forbidden to open or tune electric or electronic parts (battery, inverters, SCU, DC/DC etc.). This would
compromise the operation of the scooter.
•Before starting any installation or work, when the battery is connected to the eSkootr, remember that there is
voltage in the cables, so be careful of wrenches or tools that could generate short circuits.
•If parts of the body as finger or hair get caught in the spinning parts of the scooter, this may lead severe injuries.
Please be careful.
•If the product is lifted by holding the handlebar, there is a possibility that the scooter may be damaged. When
lifting, be sure to hold the scoter by the front fork or front pins and rear pins or footrest.
•Before starting any run remember to wear the wrist bracelet of the Wrist kill Switch.
•Be careful when handling dry ice. Use appropriate protective gloves and goggles. Don't breathe it.

The vehicle is supplied with a suggested setup. The vehicle in terms of adjustment is basic due mainly to the choice of
having rigid front and rear suspensions.
Anyway, it should be possible to play with some basic vehicle dimensions to change the vehicle behavior and
performance.
For example, as explained better in the next section it should be possible to adjust independently the front and rear ride
height.
Another parts fully adjustable is the steering damper, where is possible to set different level of damping.
Regarding the riding position, it is possible to possible moving the handlebar stem along the steering column axis.
Standard Mechanical Setup (dry conditions)
•Front Tyre: see Technical and/or Sporting Regulations
•Cold pressure: see Technical and/or Sporting Regulations
•Front Tyre: see Technical and/or Sporting Regulations
•Cold pressure: see Technical and/or Sporting Regulations
•Standard Front Fork height: Upper fork plane in correspondence of the lowest Position Mark
•Standard Rear Fork height: Center-distance on the ride height 3-hole adjuster in the SHORTER position
•Standard Steering Damper Settings: 15 click anticlockwise from full closed position
•Standard Steering Damper Spacer: N°2 spacer (5mm each) on both side
Other adjustable features on the eSkootr eSC S1-X, as better explained on the specific section of the vehicle manual,
concern the SCU controls. It is possible for the rider to select independently up to 5 different maps for the front motor and
the rear motor. With these maps basically it is possible to control the level of power for each motor and manage the
“shape” of the output curve of the motor.

The weight of the vehicle in running condition is 41.5kg.
In case the BOP (Balance of Performance) request is to add weight on the vehicle, there is the possibility to add some
ballast under the chassis on the keel area.
The ballast must be fixed with 4 M6 bolts and its maximum allowed size is 100x405x11 mm.

Set-Up Adjustments

17
|eSC S1-X –User manual
Experienced mechanics are required to work on the front suspension assembly as incorrect assembly could compromise
the safety of the vehicle.
Bearing Preload
The main thing that needs to be checked every time is the correct preload of the steering bearing.
As for the motorbike, inside the steering support there are N°2 Single Tapered roller bearing. These kind of bearing needs
a certain preload to remove any kind of play.
The front fork must be free to turn smoothly with a minimum of preload. The amount of preload should be the minimum
to avoid any kind of bearing play and keeping the rotation of the steering as free as possible.
To adjust the preload, it is necessary to use the special wrench tool B00101082A.
The sequence to adjust the preload when the scooter is on running conditions are the following:
1) Remove the steering damper. To do this, unscrew the N°2 set screw at the extremity of the steering damper shaft
till is completely free and remove the steering damper pulling it off from its fixing pin.
2) Unscrew the M8 bolt on the lower fork plate
3) Unscrew with the special wrench tool B00101082A the lower locking bolt (below the lower fork plate)
4) Unscrew the N°2 M6 bolt locking the lower plate to the two forks
5) By using a rubber hammer,slide down the lower fork plate along the fork. In this way the locking nut for the preload
setup is completely accessible for adjusting the preload.
6) Unscrew the N°3 plastic set screw from the locking nut and by using the special wrench tool adjust the preload.
7) After adjusting the preload, screw the N°3 set screw again
8) Position again the lower fork against the locking nut and screw the M8 bolt to lock it
9) Screw and lock with the special wrench tool the lower locking bolt (below the lower fork plate)
10) Lock the N°2 M6 bolt to fix the lower plate to the two forks. (Refer to the tightening torque section for having
information about the proper torque)
11) Fit again the steering damper in place and lock it with the N°2 setscrew as explained on point 1.

Front Wheel Assembly Removal/Installation
The removal of the front wheel Assembly is necessary on the following situation:
•Brake disc Change
•Tire Change
•Motor Change –each motor is paired with some specific parameters on the related inverter: if you replace a
motor, eSC or YCOM must update the inverter software to not affect scooter performances
To remove the front wheel assembly to proceed with all the maintenances as illustrated above, it is necessary to follow
this sequence:
1) Switch OFF the main switch of the vehicle (P0)
2) Remove the front brake caliper
3) Unscrew the N°2 M10 Knut on the motor axis
4) Unscrew and remove the N°2 Unbrako M6 bolt
5) Remove the complete front wheel assembly (with the hub motor)

6) Remove the MGU wiring insulator cover positioned on the front closing plate of the chassis
7) Disconnect the N°3 MotorPhase cable. To disconnect the Motor Phase cable, usea N°10 Wrench tool and remove
the brass nut, the brass washer, and the phase cable connector.
8) Disconnect the Motor Signal cable from the front closing plate of the chassis
Image 8 - MGU Phase cable & signal connector
9) Now it is possible to remove completely the front motor assembly from the vehicle and proceed with one of the
maintenances (Brake disc change, Tyre change, Motor change)
10) Re-assembly everything following the above instruction in the opposite way. When positioning the Motor into
the forks, be careful about the correct positioning of the N°2 centering bushes on the Motor Axis. To facilitate
insertion of the motor inside the fork sheath housing, you can help yourself with the help of a rubber hummer.
NB:
•Pay attention on the motor phase order. Remember to install no.2 copper washer between all the nuts and
connectors.
•When disassemble the MGU please be careful during this operation due to voltage hazard.
•When disassemble the MGU check the tightness of the copper studs.
•At the end of the day also check the tightness of the copper studs/nuts inside the chassis
