1 safety recall, most serious first
1. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. 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.
What could happen: 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.
The fix: 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.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2018 CBR300R.
- Book a repair at any authorized Honda dealer. Quote NHTSA campaign 19V412000 (manufacturer code KK3).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-866-784-1870.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
