POWER TRAIN:MANUAL TRANSMISSION
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.
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.

The Wrench - If the right engine cover is leaking coolant on any of the models listed, this could be due to the water pipe causing a gap at the clutch cover side. Replacing the O-ring will not fix the leak. Instead, replace the water pipe.
