1974 Honda CB450K Coil Mounting, Caps & Point Sides

Check the coil installation and service components on your 1974 CB450K before choosing replacements. Bracket spacing, wire exits and electrical ratings all affect the coil comparison. Plug caps need their own specifications, while left and right contact points remain separate reference-based purchases.

1974 Honda CB450K · Ignition Systems, Coils & Plugs Buying guide

Compare mounting orientation with the complete wire layout

The 12V coil has 5-ohm primary resistance, one output and approximately 80mm mounting centres. Its beige-Honda-coil note requires reversed mounting. Both cap products are sold individually without a resistance figure; point sides and condenser references must be matched separately.

Parts to consider

Honda CB Ignition Coil ~ Replaces 30500-292-672 Coil with attached wires and a mounting noteCoil supplies a 19-inch plug wire, 6.5-inch blue lead with dual female bullet connector and 5.25-inch black/white lead with male bullet connector. Sold individually. Match the approximately 80mm mounting centres and the beige-coil reversed-mounting requirement together.View part Universal Motorcycle Spark Plug Cap ~ VB05F VB05F cap with electrical details to confirmAftermarket cap sold individually for the named Honda applications.

Assess the coil on an altered bracket without relying on spacing alone

The coil comes with its leads already attached, and the beige-coil note changes its installation direction. Compare wire reach and bullet ends with the required paths after confirming bracket spacing. A bracket modified during earlier work still needs both mechanical and connection checks.

Identify separate point and condenser coverage

The left point lists 30204-292-003 / 30204-292-154, and the right lists 30203-292-003 / 30203-292-154. Condenser references are 30250-369-004 / 30280-292-672 / 30280-292-671. Confirm each purchase’s supplied quantity when planning service at more than one position.

Matching the ignition installation before ordering

What should I compare before replacing a beige coil on a changed bracket?

The replacement requires reversed mounting because the wire exits differ. Compare the actual bracket, approximately 80mm centres, all stated lead lengths and connector paths in that orientation. Establish the missing attachment details where a previous bracket change affects the installation.

How should I choose a cap when the ignition system has been changed?

Confirm the new ignition’s required cap resistance and plug/lead attachment, then establish the chosen cap’s specifications. VB05F and YB05F listings give no resistance figure. Their application lists do not determine every requirement of an ignition substituted during earlier work.

What information should I retain when renewing only one contact point?

Record the removed component’s side and reference and compare its attachment. Left 30204-292 and right 30203-292 products have distinct references. Confirm supplied quantity separately if other ignition components will also be renewed.
