The SIM-1M electric speed correction module adjusts for Sportbike and Metric Crusiers equipt with electric speedometers to correct the speedometer and odometer after a change in tire size, pulley size or transmission gearing. The SIM-1M splices between the stock Sportbike or Metric Crusiers transmission sensor and the original speedometer and is easily tucked away into the bike's wiring harness after adjustment is complete.

• Cutting or splicing is required.
• Two push button switches allow the original speedometer reading to be increased or decreased easily.
• Ability to correct the speed to within 1 MPH or KPH from 50% to 284% of the original reading.
• Sealed completely from water, dust, and dirt.

The new SIM-1M comes in a smaller size for easier mounting and allows more room for calibrating more bikes.
