On mine, I used the stock switch - but I relocated it to a place behind the side covers, on the battery box that I built.  It is operated by a cable made using bicycle brake cable.

I will get a picture of what I did......

I will have to check it!
This is gonna be tough!
I'll just lay face down on the seat , use my feet for clutch & throttle , shift with one hand & rear brake with the other , hang my head over the rear of the tracker seat so I can see the brake light and find a bumpy road and check it !
Sounds like fun , Be right back.


Nope doesn't even flicker!
Shock springs a tad on the stiff side.
