1982 Honda CB450SC Nighthawk · Tach & Speedo Buying guide

Separate cable maintenance from a custom instrument plan

The Japanese-made cable replaces Honda reference 44830-MA5-670 for the listed 1982 application. The MPH and KPH instruments offer different scales and calibrations; neither listing promises a direct stock replacement. A drive-opening plug is relevant only if the original cable is deliberately removed.

Inspect the parts the cable connects

A fresh cable cannot repair a worn or binding instrument or wheel-mounted drive. Check those parts and make sure the cable seats at both ends, follows a route without sharp bends or tension, and receives only the lubrication its maker specifies.

Treat the gauge choice as an installation plan

Select the speed units you want, then confirm the drive calibration, cable thread and direction, housing clearance and wiring. The listed model application accompanies a custom-mounting requirement, so it does not establish stock-cluster interchangeability.

Common ordering questions

What can I check before buying a cable for a noisy or erratic speedometer?

Inspect the gauge and wheel-mounted drive for wear or binding, and check that both cable ends seat fully. The cable’s current instructions also call for routing without sharp bends or tension; a new cable cannot repair those other faults.

How do I decide between the MPH and KPH versions?

Choose the desired scale, then verify the stated calibration: 2240:60 for the 0–130 mph version, or 60 km/h at 1,400 cable rpm for the 0–220 km/h version. Both require a compatible mechanical drive and custom mounting.

What if I leave the original wheel-drive opening unused?

The listed gear plug closes that opening when the original cable is removed. One approximately 15mm-OD, 22mm-long plug is supplied; confirm secure seating and retention, plus clearance from the wheel, fork, axle and drive gear.
