Product Description
Your speedometer doesn't actually measure your speed, it counts pulses from a sensor on your wheel or gearbox and calculates speed based on your stock tire size and gearing. Change any of that, a bigger rear tire, different sprockets, a gearing swap, and the reading goes wrong. The SpeedoHealer sits inline with that sensor signal and lets you apply a precise correction factor, so your speedometer and odometer go back to reading true no matter what you've changed on the drivetrain.
Key Features
- Correction steps go down to a thousandth of a percent, and the total range covers anything from a minor tire swap to a completely different final drive ratio.
- On bikes that use the speed signal to cap top speed (some Honda, Kawasaki, Yamaha, and Can-Am models fall into this), fixing the signal also removes that artificial ceiling.
- A small detachable button on the harness lets you pull up your top speed reading whenever you want it.
- Save two separate calibration settings and flip between them with one button press, useful if you swap wheels or gearing between street and track.
- Switch the display between kilometers and miles without touching a wire, right from the unit itself.
- Before you button the bike back up, a built-in test mode lets you confirm the wiring is correct.
- Runs on anywhere from 3 to 19 volts, which matters on certain Yamaha models with a lower charging voltage, and drops into standby automatically to save power.
- A 32-bit processor reads the sensor signal in real time, so there's no lag between the wheel and the display.
- Sealed and weatherproofed, with protection built in against reversed wiring, short circuits, and voltage spikes.
- Size: 50 x 30 x 17mm (1.9 x 1.2 x 0.6 inches)
- Weight: 38g
This is the full kit: unit and harness together, one order. If you already own one of the two, don't buy it twice, get just the missing half: SpeedoHealer V4A Module Only or SpeedoHealer Harness Kit Only.

FAQ
What's included when I buy this?
Both halves: the electronic unit and the bike-specific wiring harness. It's a single order that covers everything needed for installation.
Will this fix my speedometer across its whole range, not just at one speed?
In almost every case, yes. Modern speedometers have very little linearity error to begin with, and you can check yours using the SH's built-in test mode.
I have a GPS unit or bike computer already, is there still a reason to get one of these?
Yes. GPS and bike computer sensors send far fewer pulses per wheel turn than your bike's own speed sensor, so they lag behind your real momentary speed. This corrects the actual sensor signal instead.
Can I run this alongside an aftermarket gear indicator?
Yes, it works fine with other aftermarket electronics. We recommend wiring the gear indicator between the speed sensor and the SH's white wire.
Will correcting my speedometer also raise my bike's factory top speed limiter?
Often, yes. If your stock speedometer reads a few percent fast, the limiter triggers early. Correcting that error usually pushes the limit point out far enough that you won't hit it.
