SpeedoHealer V4 TSD (Top Speed De-restrictor)


This version of the SpeedoHealer can remove the top speed restriction on those motorcycles and ATVs which are top speed limited via 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 many more).

The Top Speed De-restrictor feature is inactive by default. You may activate this feature but only for racing purposes on closed circuits, entirely at your own risk. Never use it on public roads!

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 readings, decreasing the bike’s resale value without a valid reason.

No matter what sprockets or tire size you use, the SpeedoHealer v4 will deliver precise readings to your meters. Don’t let uncalibrated readings degrade your bike’s resale value.
