Defect

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.

Consequence

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.

Remedy

Honda will notify owners, and dealers will replace the transmission main shaft, free of charge. The recall began July 8, 2019. Owners may contact Honda customer service at 1-866-784-1870. Honda's number for this recall is KK3.
