Package Contents: (1) Complete Speedometer Cable Assembly
Maintenance Note: Mechanical speedometer cables are high-wear components because the inner core is constantly spinning whenever the scooter is rolling. If your speedometer needle starts bouncing erratically between 20 mph and 40 mph, the inner wire strand has begun unravelling and rubbing against the outer casing, indicating immediate replacement is needed.
Installation Tip: When routing the new cable down through the front steering column, never allow tight kinks or sharp bends. A sharp radius increases friction against the inner spinning core, which will cause the brand-new wire to snap within a few hundred miles of installation.
Pro Tip: While you have the front wheel hub assembly apart to attach the lower cable end, always pull out and inspect the nylon Speedometer Drive Gear (the small plastic “worm gear” inside the hub). If the gear teeth are shaved flat or packed with dirt, a brand-new cable won’t solve your dead needle issue!
