Circlip May Detach and Cause Gear Misalignment

NHTSA #19V412000 · Power Train — Manual Transmission · NHTSA notice

Reported June 4, 2019 · Honda (American Honda Motor Co.)

Potentially affected: 3,898 vehicles

Repair completion: 81.72% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Honda campaign KK3 · Owners notified July 8, 2019

Defect description

Honda (American Honda Motor Co.) is recalling certain 2019 CB300R, 2018 CBR300R, 2018 CRF250L, 2018 CRF250L Rally, and 2018-2019 CMX300 motorcycles. The circlip, on the transmission's main shaft, may detach allowing for gear misalignment.

ODI #11725312

Incident: January 16, 2026 · Filed: March 18, 2026

I am submitting a complaint regarding a 2019 Honda CB300R with approximately 1,225 miles. This vehicle is subject to an open recall (NHTSA Recall 19V-412) involving a transmission mainshaft circlip that can detach and cause gear misalignment and shifting issues. Prior to service, the motorcycle exhibited a symptom where it would not shift or operate properly beyond 4th gear. The motorcycle was brought to a Honda dealership for recall service. During inspection, the dealer disassembled the engine and identified internal engine damage, including cylinder scoring and compression loss. The dealer attributed the cause to carbon buildup from old fuel and did not clearly establish whether the transmission issue described in the recall was evaluated as the root cause of the shifting limitation. Given that the recall specifically identifies shifting issues as a symptom of the defect, I am concerned that the original transmission-related issue may not have been properly diagnosed or addressed before recommending extensive engine repairs. I am submitting this complaint to document a potential issue involving recall-related symptoms not being properly evaluated or resolved.
