#SparkPlugs

Kawasaki Motors Corp., U.S.A. (KMC) has announced a recall affecting a select range of its motorcycles, specifically the 2023-2024 ZX400S and ZX400P models. This recall, identified under NHTSA Campaign Number 24V221000, includes the 2023 Ninja ZX-4RR KRT Edition, as well as the 2024 Ninja ZX-4R and ZX-4RR models. The core issue prompting this recall is the potential damage to the motorcycles' spark plugs, which occurred during the manufacturing process.

There was a time when spark plugs required constant maintenance or replacement. With improvements such as electronic fuel injection, cleaner burning fuels and more exotic metals such as iridium and platinum, modern spark plugs can last much longer than they used to, with service life stretching to 80,000 miles or more. These technological advances mean these are the best motorcycle spark plugs ever manufactured, and we benefit in several ways when it’s time to upgrade.
