USE NHTSA’S SAFETY RECALL PORTAL – THERE WILL BE A TEMPLATE ON THE
PORTAL
Re: Report of Voluntary Recall
Dear Administrator,
Pursuant to 49 CFR § 573.6, Royal Enfield North America hereby advises NHTSA that
its parent company, Royal Enfield (A Unit of Eicher Motors Ltd.), has determined to conduct a
voluntary safety recall campaign in the United States covering certain models of motorcycles –
Royal Enfield North America has received no reports of the potential defect occurring in the
United States and currently believes that the conditions that led to the potential defect in foreign
countries are not present to the same extent in the United States. However, we have decided to
move forward with this voluntary recall in the interest of our customers and the unlikely event
this may occur in the United States
THIS IS THE INFORMATION YOU’LL NEED TO PROVIDE IN THE PART 573
SAFETY RECALL TEMPLATE:
:
1. Manufacturer’s Name: Royal Enfield (A Unit of Eicher Motors Ltd.)
Manufacturer’s Agent: ROYAL ENFIELD of North America
Royal Enfield North America
226 N. Water St., Milwaukee WI, 53202
2. Identification of Potentially Affected Vehicles:
Model: Dates of Manufacture:
Himalayan March 2017 – February 2021
Component at Issue: Front and Rear Calipers
Manufacturer: Brembo Brake India PVT / LTD Chakan Company,
10 Gaye NO 307, Village, Nanekarwadi,
Chakan Maharashtra, 410501
The recall population was determined based on the usage of the specific
component at issue.
3. Total Number of Vehicles Potentially Affected: 4,891 motorcycles SOLD IN
NORTH AMERICA
4. The percentage of vehicles or items of equipment specified pursuant to paragraph
(c)(2) of this section estimated to actually contain the defect or noncompliance – less than 0.01%
5. Description of potential defect:
When the motorcycles within the population at issue are used on roads on which a
large quantity of salt has been applied during the winter for melting ice, and if
brake calipers are not cleaned thereafter, corrosion of the brake calipers can occur
which can cause the brakes to drag or braking performance could be affected or
become ineffective.
The potential defect may cause unusual and/or increased brake noise when
applying brakes, an unusual odor/burning smell near the calipers, a drag feeling
when attempting to accelerate, or unusual difficulty in pushing the motorcycle
manually. If these warning conditions are not heeded, braking performance could
be affected or become ineffective, increasing the risk of a vehicle crash.
6. Royal Enfield made the determination to conduct the voluntary safety recall.
1. Below mentioned motorcycle customer reported for front wheel dragging / locking
phenomenon while riding their motorcycle. (This incident was in the UK)
a. Case 1 : Himalayan reported on 11th Mar’20 at 2,000 Miles
2. Steps taken by Royal Enfield after the reported events.
a. Analysis and discussion with safety office, QA, etc., with dates
b. Root Cause: Joint analysis with Bosch (ABS system supplier) and Brembo
(brake caliper supplier) was performed on the affected part.
c. It was concluded that when motorcycles are used on roads on which a large
quantity of salt has been applied during the winter for melting ice, and if brake
calipers are not cleaned thereafter, corrosion of the brake calipers can occur
which can cause the brakes to drag or become ineffective.
d. Even though feedback was received only from the UK, Brake Caliper
manufacturer Brembo, advised that this phenomenon may occur in other
countries where salt is used in winter such as the US, other European Countries
and South Korea.
e. Brembo has recommended using anodized calipers to combat this corrosion for
the countries using salt to melt ice on the roads.
3. Corrective Action: To ensure there is no major damage, RE is voluntarily recalling all the
motorcycles supplied in these countries.
4. Recall: Replace Front and Rear calipers with Anodized Calipers for all motorcycles fitted
with non-anodized calipers for the EU, UK, Korea, Japan and USA.
7. Noncompliance – doesn’t apply
8. Program for Remedying Defect:
Royal Enfield, through its authorized dealers, is offering owners of potentially
affected motorcycles the complete replacement of the current non-anodized brake
calipers (front and rear) with anodized calipers (front and rear)
a. Royal Enfield of North America will begin notifying its dealer network
regarding the recall through email/dealer communication the week of
February 27th, 2023
b. Royal Enfield of North America will begin notifying the affected
customers regarding the recall through mail. The customer
communication will be sent out starting the week of March 31st, 2023
Sincerely,
Royal Enfield North America

Subject: IMPORTANT DEALER COMMUNICATION! Safety Recall Campaign
SC-31
Dear Royal Enfield Dealers:
This Service Circular is to inform you about a voluntary Safety recall announcement by Royal
Enfield of North America (RENA) pertaining to Himalayan models. It outlines the required
replacement of front and rear brake calipers and the appropriate actions to take.
Royal Enfield has discovered a brake caliper corrosion-related issue in a very small
number of Himalayan motorcycles in some specific countries outside of North America.
Upon investigation, it was revealed that this corrosion is brought about by sustained,
long-term exposure to riding on roads treated with certain salts or a combination of salts,
to prevent formation of ice during winters. This corrosion causes damage to the brake
caliper piston bore and assemblies, and can result in unusual braking sound, increased
brake drag, unusual difficulty in pushing the motorcycle manually and may impact
braking action.
To date, RENA has received no reports or complaints from our dealers or customers related
to this concern. RENA has decided to voluntarily launch this recall in the very rare instance
this may occur
This recall pertains to model year 2017-2021 Himalayan models. The brake calipers both
front and rear will be replaced through this process. Please find the Service Circular,
Technical instructions, Parts ordering, and claim filing process information on the following
pages.

voluntary safety-related recall in the United States covering Himalayan models. RENA has discovered a
brake caliper corrosion-related issue in a very small number of Himalayan models.
RENA has received no reports or complaints from our dealers or customers related to this concern.
Description of the concern outside of North America:
Royal Enfield has discovered a brake caliper corrosion-related issue in a very small number of Himalayan
model motorcycles in some specific countries outside of North America. Upon investigation, it was
revealed that this corrosion is brought about by sustained, long-term exposure to riding on roads treated
with certain salts or a combination of salts, to prevent formation of ice during winters.
This corrosion causes damage to the brake caliper piston bore and assemblies, and can result in unusual
braking sound, increased brake drag, unusual difficulty in pushing the motorcycle manually and may
impact braking action.
Royal Enfield of North America will begin notifying the affected customers regarding the recall through
mail the week of February 6, 2023. The brake calipers both front and rear will be replaced through this
process.
PLEASE BE ADVISED, IT’S A VIOLATION OF FEDERAL LAW FOR A DEALER TO DELIVER A NEW
MOTOR VEHICLE COVERED BY THE NOTIFICATION UNDER A SALE OR LEASE UNTIL THE
DEFECT IS REMEDIED
Please find attached:
1. The service circular (shows visual difference between anodized and non-anodized)
2. Technical reference material (from service manual)
3. Campaign claim / reimbursement process
4. A copy of the customer letter
We ask that you please read these materials thoroughly and share them with all of your staff as soon as
possible. Copies of this notification and its attachments can be found on the Dealer Portal and can be

GENERAL PRECAUTIONS
 Check the system for any fluid leaks at banjo union joints, damaged brake hose etc. at periodic intervals as detailed
in the maintenance schedule.
 Whenever checking brake fluid level, ensure vehicle is on its centre stand and the fluid reservoir is parallel to the
ground, whenever checking fluid level.
 Cover motorcycle painted surfaces, plastic and rubber parts while overhauling or bleeding a brake system. Do
not allow brake fluid to come in contact with any parts of the motorcycle as brake fluid has highly corrosive
properties.
CLEANING
 Clean master cylinder filler cap before removing.
 Use only fresh brake fluid to clean rubber and other parts of the hydraulic brake system. DO NOT use any
petroleum based cleaning solvents, water or detergents etc.
INSPECTION:
 Inspect brake fluid level is always between the MAX and MIN level markings in the reservoir.
 Prior to riding the motorcycle every time, check brake disc inside and outside surfaces carefully for any
contamination with oil, grease, slippery substances, brake fluid etc. as these will render the braking system
ineffective. In case of any contamination, wash the brake disk with water and mild detergent to remove the
contaminations, clean well with a good degreasing agent, blow compressed air to dry the brake disc thoroughly.
 Inspect brake hose joints; reservoir and wheel caliper ends for any traces of fluid seepage or leaks. Check and
correct the leaks immediately, if any noticed.
 Inspect Brake hoses for any damage, cracks or cuts, ageing etc and replace damaged parts immediately.
 Inspect brake pads for embedded foreign objects, abnormal wear, age hardening of friction material etc.
 Inspect and ensure the pads are not worn out beyond the wear indication limit marks on the pads. Replace pads
as soon as they have reached the wear limit marks
 Check rubber seals on the plunger for wear, cracked edges or any other damage. Replace seals whenever the
plunger is removed
 Check master cylinder housing and piston for any scoring, pitting due to corrosion or any other damages.
 Check the master cylinder bore for any damages, scoring marks etc.
 Check piston outside surfaces for any damages, scoring marks, corrosion etc. Replace pistons if any of the above
is observed.
CAUTION:
 Use only DOT 3 or DOT 4 grade brake fluid from a sealed container. Do not mix different types of brake fluid
as they may not be compatible.
 Whenever the disc brake system is overhauled, ensure that the old fluid is drained out completely and then filled
with fresh brake fluid ONLY from a sealed container.
 In case of any brake fluid contamination in the brake system, the contaminated brake fluid must be flushed out
completely from the entire system, the internal parts cleaned well, filled with fresh brake fluid and the brake
system bleeding must be carried out.
