Speedohealer V4-TSD with Top Speed De-restrictor feature

The SpeedoHealer TSD model has a Top Speed De-restrictor feature. It is inactive by default. You may activate this feature only for racing purposes on closed tracks, entirely at your own risk. It must not be used on public roads!

This unit can be configured to avoid the top speed restriction on motorcycles and ATVs which have a top-speed limitation based on the speed signal (such as the CBR1000RR, VFR800X, GL1800, VFR1200F, ZX-10R, ZX-12R, ZX-14, FZ-09, MT-09, YZF-R1, V-Max, Can-Am, Kawasaki, Polaris ATVs and more).

You can set the TSD unit to either ‘freeze’ the speed signal to the ECU at a specific threshold, or apply a stronger calibration value so that the speed signal will be increased at a slower rate above the set threshold.

The SH-V4-TSD unit is compatible with all SH-V4 Harness kits.

On most motorcycles the factory speedometer error can be as high as 10%. So even a modest gearing change can have the speedometer off by 15%. Changing the sprockets or tires will also result in higher odometer reading, decreasing the bike’s resale value without valid reason. The SpeedoHealer is an affordable, convenient and very simple way to sort these speedo and odo issues. Compatible with all motorcycles, ATVs/UTVs with non cable driven speedometer. Get your fix today – You won’t find any better alternative on the market! The SpeedoHealer is the most popular and most reliable calibrator in the world – acknowledged by thousands of happy customers worldwide.

Note: The new SpeedoHealer TSD has the ability to remove the top speed limiter on certain vehicles for racing purposes, including: CBR1000RR, VFR800X, VFR1200F, ZX-10R, ZX-12R, ZX-14, FZ-09, MT-09, R1, V-Max, Can-Am, Kawasaki, Polaris ATVs and many more.User Manuals
