Sudden breakage in a rear cushion connecting plate could cause riders to crash.
American Honda Motor Company issued a voluntary safety recall on April 8, 2021, for certain 2021 Honda CBR1000RR-R Fireblade SPs, due to the possibility of incorrectly installed rear cushion connecting plates. On some bikes, one or both of these pieces (there are two per bike) may have been installed upside down, which means they’re not securely connected to the bike. This could lead those plates to unexpectedly break, which would immediately cause a vehicle height drop. Such sudden action could increase a rider’s risk of a crash.
A total of around 89 bikes may be involved in this recall, which represents an estimated 1 percent of this model that may have this specific defect. Affected bikes were produced between April 28 and July 29, 2020, and have VINs ranging from JH2SC821*MK000004 to JH2SC821*MK000092, per American Honda.
The company also issued a stop sale notice on certain 2021 CBR1000RR-R SP bikes until they can be inspected, and if necessary, have any incorrectly installed rear connecting plates replaced with new ones, as well as their corresponding seals. A new service bulletin pertaining to this issue offers very clear diagrams on how to correctly install the rear cushion connecting plates, as well as how not to do so. You can view it in the NHTSA documents if you like.
