MPH and KPH versions offer several finishes, but matching color does not establish compatibility. Check the advertised ratio and physical mount first, then account for illumination and any indicator connections.

The chrome mini KPH versions have a 0–220 KPH face; the all-black mini KPH version stops at 140 KPH. Their finish names alone do not describe the dial. Compare the pictured scale with the product description, then check body size and mounting provisions.
The mini speedometers combine illumination with high-beam, neutral, oil-pressure and turn indicators. Their presence does not establish direct connection to the CB550SC harness. Confirm each connection and the mounting bracket separately. A vintage-style speedometer also needs custom mounting and a verified mechanical drive match.
These are custom individual gauges. The mini listings explicitly say they are not stock-type replacement speedometers, and the vintage-style listings require custom mounting. Check drive, clearance and connections rather than expecting the original instrument assembly to accept them.
The mini speedometer listings include a mounting V-plate, but require a separately purchased bracket. Compare the proposed bracket and gauge position with your motorcycle before ordering; the plate alone does not establish a complete mount.
No. The CB550SC’s original tachometer uses an electrical signal, while its speedometer connection is mechanical. Assess each instrument independently. Matching diameter or finish cannot establish tachometer signal compatibility, speedometer drive ratio or suitable mounting.
