The difference between the standard SH-V4 and SH-V4-AB is that the standard model has a remote push button for top speed recall, while the AB model has a remote switch which allows INSTANT switching (even while riding) between the A and B memory banks.
The SH-V4-AB 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. 

• Resists viscosity breakdown 6X better than Harley-Davidson* SYN3* for improved protection against compensator and transmission gear wear.1• Resists extreme heat to help keep engines clean and efficient.• Reduces wear and deposits for maximum engine compression and power.• Convenience of one lubricant for all three sumps.

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.

Remove the bulky and heavy exhaust servo motor when replacing the end-can or the full exhaust system. Plus, it will get rid of the FI light coming up when disconnecting the servo motor. Get the job done right with the help of the tiny, but mighty ESE!
Introduction
OEM exhaust cans and systems won’t win a beauty contest these days (and rarely did they in the past), they weigh a lot more than the aftermarket counterparts, sound crap and you never reach the bike’s full potential with them. Whatever is the reason to change your end-can or whole system, removing the exhaust valve will leave you with the dreaded FI light. Install the ESE to take care of that so that the FI light will come on only when it has to – when there’s a trouble with the engine.
