Royal Enfield Genuine RAB00081/A – Toner Front Wheel (ABS Tone Ring / Reluctor Ring) – Classic 350 ABS BS4 & Thunderbird X 500 ABS

If your ABS warning light is on, your front wheel speed reading is erratic, or you’re replacing the front hub/rotor assembly, the Toner Front Wheel (also called ABS tone ring / reluctor ring) is one of the first parts you should inspect. Royal Enfield RAB00081/A is the genuine OEM front wheel toner ring designed for ABS-equipped front wheels where the wheel speed sensor reads the ring’s teeth to calculate wheel speed for ABS modulation.

This part mounts on the front wheel / hub side (model-dependent) and must be installed perfectly aligned—any bending, wrong orientation, or damaged teeth can cause ABS sensor errors. It’s a small, inexpensive part that prevents big headaches like recurring ABS faults, unnecessary sensor replacement, and repeat workshop visits.

✅ Verified fitment: Classic 350 ABS (BS4 / BSIV) and Thunderbird X 500 ABS (BS4 / BSIV).
⚠️ Not for non-ABS (halogen/non-ABS variants)—those wheels don’t use this toner ring.

Ideal for accident repairs, wheel rebuilds, ABS troubleshooting, and preventive replacement when doing major front-end work.
