REVISED: November 26, 2019
2018-2019 MULTIPLE MODEL – TRANSMISSION MAINSHAFT SAFETY RECALL
BACKGROUND
Honda is launching a SAFETY RECALL on certain model year 2018 CRF250L/LA, CRF250LR/ LRA RALLY, 2018 CBR300R/A, 2018-2019 CMX300/A and 2019 CB300R/A motorcycles to replace the transmission mainshaft, which may have been improperly machined during manufacturing. The machining error could result in a mainshaft circlip not completely seating into the circlip groove, which could cause the circlip to become loose. A loose mainshaft circlip could be dislodged, resulting in damaged transmission gears, which could cause the rear wheel to lock-up. A rear wheel that locks-up increases the risk of a crash.
Honda will provide a new transmission mainshaft to replace the defective part.
Service Bulletin Multi-Model Transmission Mainshaft #1 includes the affected models and VIN ranges, parts and warranty claim information and repair procedure information to replace the transmission mainshaft.
Honda will notify customers by letter advising to make an appointment with an authorized Honda dealer to perform the recall repair by replacing the transmission mainshaft with a new part.

TEXT OF CUSTOMER LETTER
July 2019 NHTSA Recall 19V-412
IMPORTANT SAFETY RECALL
This notice applies to your vehicle: XXXXXXXXXXXXXXXXX
Dear Honda Powersports Customer:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
WHAT IS THE REASON FOR THIS NOTICE?
Honda has determined that a defect which relates to motor vehicle safety exists in certain:
2019 Honda CB300R
2018 Honda CBR300R
2018 Honda CRF250L
2018 Honda CRF250L Rally, and
2018-2019 Honda CMX300 (Rebel) motorcycles.
A circlip that secures the transmission gear to the main shaft could detach and result in gear misalignment. A misaligned gear can:
1) shift the transmission from neutral into gear during engine start, potentially resulting in unexpected motorcycle movement; or
2) seize the transmission and rear wheel while the motorcycle is in motion.
Either outcome increases the risk of crash or injury.
A misaligned gear could cause abnormal engine noise, which might warn you of the defect, but either outcome could occur without first
experiencing abnormal engine noise.
WHAT WILL HONDA DO?
The dealer will replace the transmission main shaft for free.
WHAT SHOULD YOU DO?
Please call any authorized Honda motorcycle dealer and make an appointment to have
the transmission main shaft replaced for free. Once you make an appointment for your
motorcycle, be advised that the replacement process may take approximately 5 to 7
hours depending on your model (please see chart). However, your dealer can provide
you with a better estimate of the overall time for this service visit, as it may be necessary
to make your motorcycle available for a longer period of time. If you are not the only rider
of this motorcycle, please advise all other riders and passengers of this important
information!
For assistance locating a Honda motorcycle dealer, you may call Honda Powersports Customer Service at:
(866) 784-1870 or use the “find a dealer” option on www.powersports.honda.com.
CHECK YOUR MOTORCYCLE FOR OPEN RECALLS
You can check your motorcycle’s eligibility for repair under this or any other recall. Please access the Honda recall lookup tool at
www.powersports.honda.com/recalls.aspx and enter your VIN.
OWNER INFORMATION
You received this recall notice because government regulations require that notification be sent to the last known owner of record. Our
records are based primarily on state registration and title data, which indicate that you are the current owner of this motorcycle. If this is
not the case, or if any of the information is incorrect, please complete, sign and return the Information Change Card and we will update
our records. If you are a lessor of this motorcycle, Federal Regulations require you to forward this notice to your lessee within ten days.
DO YOU STILL HAVE MORE QUESTIONS?

additional assistance, you may contact Honda Powersports Customer Service toll free at (866) 784-1870.

reasonable period of time (within 60 days from the date you first contacted the dealer for a repair appointment), you may submit a
complaint to the Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Ave., SE, Washington, DC 20590.
