KK3 – Transmission Mainshaft Safety Recall – 2018-2019 Honda Motorcycles

June 4, 2019 NHTSA CAMPAIGN NUMBER: 19V412000

Circlip May Detach and Cause Gear Misalignment

A misaligned gear can shift the transmission from neutral into gear during engine start, potentially resulting in unexpected motorcycle movement or seize the transmission and rear wheel while the motorcycle is in motion. Both conditions increase the risk of crash or injury.

 

NHTSA Campaign Number: 19V412

Manufacturer Honda (American Honda Motor Co.)

Components POWER TRAIN

Potential Number of Units Affected 3,898

MULTI-MODEL:
TRANSMISSION MAINSHAFT #1
ISSUED: June 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.
