• This module allows you to recalibrate most 95-06 OEM electronic speedometers when changing tire size, pulley, or final gearing
• Easy installation – simply plugs in between the pickup sensor and the stock wiring harness
• Allows small step corrections of less than 1 mph
• Correction range of 50% to 200%
• No power required to maintain calibration when the bike is parked
• Two sealed buttons allow easy resetting of the speedometer reading while the bike is in motion
• A must for custom builders using electronic speedometers

Fits: 1996-2006 Harley Softail, 1996-2006 Touring models, 1996-2005 Dyna, 1995-2003 XL

Later models (2004-up Sportster, 2006-up Dyna and 2007-up Softail and Touring models) require hardwiring into stock harness, speed correction can be made up to Harley's factory margin of error, typically 3-5% of actual speed reading.  If correction is made beyond this, it may result in the loss of the 6th gear indicator light and cruise control.
