The auto shift control module allows the motorcycle to make automatic upshifts at a preset RPM. It is useable on all motorcycles equipped with a Pingel Electric Speed Shifter and a Dyna Shift Minder (used to set the RPM). The module is easy to install with two plugs; one for the shifter's dual button handlebar control harness and an additional plug to install a Dyna. It is recommended that a toggle switch be installled to arm or disarm the auto shift. The Auto Shift Control Module uses state of the art electronic components and is very compact measuring at 1-1/2" wide, 2-1/2" long and 3/8" high. Dyna Shift Minder not included.
