236986 Electronic Speedometer Adjustment Unit

The Dakota Digital electronic speedometer adjustment unit is a specialized tool for calibrating speed and odometer readings on Harley-Davidson motorcycles. This module is essential when changing tyre sizes, pulley ratios, or installing a different transmission, such as a six-speed upgrade. The unit allows for precise corrections from 50% to 200% of the original reading, adjustable in small increments via two sealed push-button switches. The module is completely sealed against water, dust, and dirt, ensuring long-term reliability. It stores the correction factor even when the battery is disconnected, making it a set-and-forget solution for maintaining accurate instrumentation on modified bikes.
