Panthera electric starter has been designed to fit YZ125 2005+ as a bolt on unit. No modification to the original engine is needed.

This kit is made to run with the OEM flywheel. The flywheel receives a new supplied heart that you will rivet on to receive the one way gear made to crank the engine from the flywheel side.

The billet Panthera starter cover comes with an assembly of gears, all mounted on sealed bearing, no fast worn out bushing like other manufacturers.

The system comes with its own complete wiring and battery box made to bolt to the YZ125 subframe, inside the airbox.

The motorcycle will start around 200 times before needing a battery charge.

Additional weight for the whole unit is 4.9 pounds with battery*.

*Battery is not included as they cannot be shipped internationally.
