Honda Rancher 350 ES shift bypass kit — the actual kit, photographed in our shop
The actual kit — our photo, our bench. Not a render.

If you can hand-shift the transmission through all the gears with the shifter on the lower left of the motor, you've checked battery condition and connections, tested or replaced the up/down shift buttons on the left handlebar switch, and already tried a known-good shift motor — but you still have a flashing shift code — this kit may solve your electric shift headaches.

Great for diagnostics of the Honda E.S.P. computer shift system — it quickly isolates a mechanical problem from an actual electric sensor or computer problem.

The kit runs on sealed waterproof 5-pin relays, the same style you can pick up at any local auto parts store. One relay powers the upshift, the other controls the downshift — if one ever fails years down the road, you're minutes and a few dollars from back on the trail.

It bypasses the angle sensor, speed sensor, shift computer (ECU), forward/reverse sensor and most of the main wire harness — converting your electric shift to manual-style control without computers or sensors, while you keep shifting with the stock thumb buttons.

The Last Fix Your Rancher Will Ever Need.

Stop replacing parts. Fix it once with the ES Shift Kit — free shipping, 2-year warranty.
