Inertia disc Power Booster Honda eSP 125/150 Yuminashi

The manufacturer Yuminashi has thought of all the details, and has produced a Power Booster inertia disc to improve the torque of the PCX 125cc and 150cc models.

Torque is a very important part of these models, as they are quite heavy vehicles for the power they have, and they do not stand out for their aerodynamics.

All this means that the PCX125, PCX150 and their siblings are not easy scooters to lift at high speeds and that is why Yuminashi has developed the inertia disc.

The inertia adjustment is an unobtrusive improvement, but it really is an improvement that will help you achieve higher top speeds.

Installing the Power Booster disc:

• Remove the radiator and fan at the top of the flywheel with the 3 screws.
• Install the POWER BOOSTER disc between the flywheel and the fan
• You will need the 3 larger screws (stainless steel M6x25mm) to install the POWER BOOSTER disc between the flywheel and the fan which you will need to buy separately.
• After this, you can reinstall the radiator in its normal position with the original bolts.
  
  

Attention*:to install the Power Booster disc on 150cc PCX or SHI ABS engines, be sure to install some washers between the radiator, otherwise the fan on top of your Power Booster will touch the radiator and damage it.

*For125cc you do not need to make this modification.

Note: The inertia disc no longer bears the Yuminashi logo and has become shiny due to the new zinc protective coating placed as a top coat to protect against rust.
