4 recalls across 5 model years
The Honda CBR300R has 4 recalls spanning 2015 through 2021, with the most serious affecting 2015-2016 models where a crankshaft machining defect can cause the connecting rod bearing retainer to fail, stalling the engine without warning and raising the risk of a crash.
The 2018 model year has a transmission recall where a circlip on the main shaft can detach, allowing gears to misalign. This can cause the transmission to jump from neutral into gear during engine start, moving the motorcycle unexpectedly, or it can seize the transmission and rear wheel while riding. The 2020-2021 model years have a rear reflector that may not meet brightness standards, reducing how visible the motorcycle is to drivers behind it at night or in low-light conditions. Going back to 2015, a separate issue involves sealant applied incorrectly to the starter relay switch, which can cause a loss of electrical power and stall the engine while riding.
