Kawasaki Motors Corp, USA (Kawasaki) is recalling certain 2021 Z400 ABS (ER400D) Ninja 400 (EX400H) and Ninja 400 ABS (EX400G) motorcycles.  The problem is the result of a faulty camshaft chain tensioner.

Kawasaki says that the cam chain tensioner may have been improperly heat-treated.  As a result, the tensioner may not be strong enough for its intended purpose.  Kawasaki warns that continued use can result in camshaft chain tensioner damage, noisy operation, and in the worst case, engine stalling, which could result in loss of control and increase the risk of a crash.  Accordingly, Kawasaki is advising the owners of affected motorcycles to not ride their motorcycles until the repairs have been completed.

The list of affected motorcycles is as follows:

MAKE MODEL YEAR
KAWASAKI ER400D 2021
KAWASAKI EX400G 2021
KAWASAKI EX400H 2021

Kawasaki will notify owners and dealers will replace the camshaft chain tensioner free of charge.

This recall began on December 21, 2021.  If you have any questions, you can contact Kawasaki customer service at 1-866-802-9381 and cite Kawasaki recall number MC20-13.  Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 or go to www.safercar.gov.
