This page covers 1 recall and 14 owner complaints for the 2013 Kawasaki Ex300.
Complaints about the 2013 Kawasaki EX300 (Ninja 300) cluster around two main areas. The most-reported issue involves the powertrain, specifically handlebar wobble or shake that owners describe occurring during deceleration, typically in the 35–55 mph range. Several owners point to the steering head bearing as the source, reporting the wobble appears early, sometimes within the first few hundred miles. Engine stalling is the second consistent theme: owners describe the engine dying when the clutch is pulled in, particularly during downshifting or when coming to a stop. RPMs reportedly drop below idle speed and the engine cuts out, sometimes repeatedly within a short ride. Some owners tried raising the idle speed manually without resolving the issue. The fuel and propulsion system attracted a smaller share of complaints, though the stalling behavior likely overlaps with those reports given the symptoms described.
