Kawasaki has rolled out a recall for the 2019-2022 W800. The vibrations of the engine block can break the wiring of the horn, causing it to no longer function.
As early as March 2020, Kawasaki Heavy Industries (KHI) received the first report from the Japanese distributor (KJI) of a horn that stopped working due to a break in the horn wiring plug.
Research showed that there was a fatigue fracture and that the fracture was therefore not the result of an impact. KHI tried to recreate the break, but failed. In the course of 2020, KHI received another 6 notifications from the Japanese market.
In January 2021, KHI tried to determine the frequency of the vibrations generated during driving and whether it was higher than in other models, which could lead to a fatigue fracture earlier. The number of incidents continued to increase, in the period March – July 2021 KHI received another 9 reports from the Japanese market.
Initially this was unsuccessful, only after the frequency and amplitude of the motor vibrations were modulated could the premature failure be simulated, but KHI thought that the circumstances were so exceptional that in practice it rarely lead to such a fracture.
Despite this, KHI decided to develop a rubber damper to reduce the vibrations and then roll out a recall. At the Kawasaki dealer, the complete horn unit will be replaced by the new one with rubber damper.
