Instrument & Gauge Parts
About Instrument & Gauge Parts
These are the parts around a gauge: the mounts and cups that hold it, brackets that move a speedometer to a new position, adapters, and interface or plug-in units that connect a gauge to the bike. Riders look here when they have a new gauge but nowhere to put it, when taller bars block the stock view, or when a gauge needs an adapter to connect.
Mounts are sized to what they clamp onto. The samples include gauge mounts for 1-inch and 1.5-inch T-bars, a clamp for 1.25-inch risers and a relocation bracket for a 39 mm fork. Match the bar, riser or fork diameter, then the size of the gauge or cup. Harley-Davidson mounts are listed by model and year, such as Dyna, Sportster and Softail. Check that a new position does not block the headlight, the controls or the full turn of the bars. Some items here are electrical, such as a data bus interface for 1999 to 2013 Harley-Davidson models, a tachometer adapter and a direct plug-in speedometer, so read what each one connects to.
Brands in this category include COLONY, Drag Specialties, Dakota Digital, ACCEL and SLYFOX. The gauges themselves are in Individual Gauges and Instrument Clusters, and extension wiring is in Wiring Harnesses, Cables & Connectors. The whole group is Instruments & Gauges.
FAQs on gauge mounts and relocation parts
How do I know which gauge mount fits my handlebars?
Measure the diameter of the bar, riser or fork tube where the mount clamps, and compare it with the size in the listing, such as 1 inch, 1.25 inches or 39 mm. Model-specific mounts list the bike and year. Also check the cup or gauge size the mount is made to hold.
What is a gauge relocation kit?
A relocation kit moves a speedometer or gauge from its stock position to a new place, such as the handlebar or the fork, using a bracket and clamp. Moving a gauge may mean the wiring or cable no longer reaches, so check whether an extension is needed.
Do I need an extension harness when I relocate a gauge?
Often, yes. If the new position is farther from the connector than the stock wiring reaches, you need an extension of the right length and connector type. Check the listing and measure the route, leaving some slack for steering.
Can I mount a gauge on the handlebar of any bike?
Only if the mount fits the bar diameter and the gauge does not block your view of the road or interfere with the controls. Check the bar size first. Turn the bars fully both ways after fitting to make sure the gauge and its wiring clear everything.
How do I keep a gauge mount from loosening?
Use the supplied hardware, tighten it to the maker's specification and, if the instructions call for it, use thread locker. Vibration works loose anything that is not secure, so recheck the mount after the first ride and support the wiring so it does not pull on the gauge.
