Royal Enfield 124559/3 – Ignition Coil (Lucas Type) 12V – Genuine Replacement for Select Models

Restore strong spark & smooth running—Lucas-type 12V ignition coil replacement for Royal Enfield setups that use an external HT coil.

Description 

If your Royal Enfield is showing hard starts, misfire under load, weak pickup, or erratic idling, a weak ignition coil is a common root cause. The Royal Enfield 124559/3 Ignition Coil (Lucas Type, 12V) is built as a direct replacement-style external ignition coil for motorcycles that use this coil format in their ignition system.

This coil is designed to step up 12V battery power into high voltage for consistent spark at the plug—helping your engine start easier, idle cleaner, and pull more reliably through the rev range. It’s a popular choice for restoration/maintenance where the motorcycle uses a Lucas-pattern coil (match your existing coil physically + connector style before ordering).

⚠️ Important fitment note: Royal Enfield used different ignition coil designs across platforms/years (carb/EFI, UCE/J-series, etc.). This listing is intentionally fitment-safe: please confirm by matching your existing coil or share your VIN/model details (or the RE spares portal compatibility list) for a guaranteed fit.
