On most modern motorcycles, with factory speedometer error being as high as 10%, even a modest sprocket gearing change can have the speedometer off by 15%. The sprocket change will also cause higher odometer reading, creating a negative resale factor for no valid reason. The SpeedoHealer is an inexpensive, convenient and very simple way to fix your speedo and odo. It is compatible with all motorcycles with non-cable driven speedometer and any vehicle with a 3-wire speed sensor or 2-wire ground switch sensor (cars use Universal harness).

The SpeedoHealer is the most popular and reliable calibrator in the world – acknowledged by thousands of happy customers worldwide.

You won't find any better NOR a lower cost alternative on the market!


Easier to program, review and update the stored parameters.Extended calibration range: -99.9% to +9999.9% in steps of 0.1% Which means the signal can be adjusted from 1/1000 to x100, in increments of 0.001 This range is efficient even for the most radical sprocket conversions and suitable for all kind of custom applications as well.


Allows storing two independent calibration values and switching among them is possible by the press of a button. There is a clear, visual confirmation of the active bank and value in use. Useful for road & track setting when changing gearing or wheel size. Also, easy to bypass the speed limiter when on the track.
Detachable Remote button for the Top Speed Recall feature is now standard.


The unit takes less space with the wiring harness connected


Black, high quality, flame retardant and shielded wiring harness - blends in with the other cables.

Km/h conversion:
Change from Km/h to MPH by the press of a button.


Confirm installation before leaving the garage.


30% smaller and lighter unit compared to SHv3. Full SMD design. The smallest and lightest calibrator ever built.


Works from as low as 3V supply voltage, up to 19V. Means even easier installation for all Yamaha bikes and some other models. Reduced power consumption + auto stand-by.


32-bit processing ensures high accuracy and immediate response to the input signal (no lag).


100% weather proof. Every unit is fully tested, guaranteed to work. All leads are protected against reverse voltage, short circuits and high energy transients. 


A great thing about Speedo Healers is that they can be used on any vehicle with a 3-wire speed sensor or 2-wire ground switch sensor. It also is used by builders of custom race vehicles, trikes, and dragsters which use donor parts but need speedometer accuracy. If needed, HealTech can make a custom Speedo Healer unit with longer or shorter wiring harness.
For vehicles using 2-wire inductive sensor (BMW motorcycles & some autos)
Interfacing mixed sensors/gauges (e.g. 3-wire sensor with 2-wire gauge)
