Electronically suspends the ignition system, allowing the transmission to smoothly shift up or down with just the push of a button. Shift up at partial or full throttle and back down at the touch of a button. No need to use the foot shifter; clutch is used only when starting or stopping. Works for normal street riding or full-throttle shifting. Perfect match for male and female riders who own bikes that require a lot of hand strength to pull in the clutch lever. OEM shifting ability is retained after installation.

Includes electronic ignition kill module and step-by-step instructions with photos for easy installation. Universal kit also available with dual-button handlebar control to fit 7/8" or 1" diameter handlebars/clip-ons; installation may require purchase of frame tube brackets for shift cylinder mounting (sold separately). Made in the U.S.A. Not suitable for 4-speed transmissions.
