Here's why:
* Mechanical Speedometer: The 1976 FXE uses a mechanical speedometer, which relies on a cable connected to a drive gear that turns with the front wheel. This rotation is what powers the speedometer needle.
* No Other Drive Locations: There are no other rotating components on the motorcycle that can provide a consistent and accurate rotation to drive the speedometer cable.
Alternatives:
* Electronic Speedometer: If you want to avoid the front wheel drive, you could consider converting to an electronic speedometer which typically uses a sensor mounted on the rear wheel or transmission. However, this would involve significant modifications to your bike's electrical system.
* GPS Speedometer: Another option is a GPS-based speedometer which uses satellite signals to determine speed. These are readily available and relatively easy to install.
Note: Before making any changes to your motorcycle's speedometer system, it's crucial to consult a qualified mechanic or expert to ensure proper installation and functionality.
