The difference between the base model SH-V4 and the SH-V4-AB is that the SH-V4-AB has a switch on the remote control that allows you to switch instantly between memory zones A and B, even while driving.
The SpeedoHealer v4 is the world's leading and most popular speedometer and odometer calibrator. Regardless of changes in gear ratio or tire size, the SpeedoHealer v4 ensures accurate speed and mileage readings, providing reliable performance and absolute precision for your motorcycle's instruments.
On most motorcycles, the factory speedometer has an error margin of up to 10%. Even a small change in the gear ratio can increase the error to as much as 15%. At the same time, changes to gears or tires also affect the odometer readings, recording more kilometers than actually traveled and negatively impacting the motorcycle's resale value. It features a remote control button for resetting the maximum speed.
SpeedoHealer is an affordable, practical, and easy-to-install solution that accurately corrects speedometer and odometer readings. It is compatible with all motorcycles as well as ATVs/UTVs equipped with an electronic (non-mechanical) speedometer.
The SH-V4-AB unit is fully compatible with all SH-V4 wiring kits.
CAUTION: You must verify that the product and wiring are compatible with your machine's model and year.
