ATHENA Engine Oil Seal Kit for KAWASAKI KLX 110 2002-2025

On KAWASAKI KLX 110 from 2002 to 2025, the ATHENA P400250400030 engine oil seal kit fits in place of the original part. Every shaft that passes through the crankcase runs in an oil seal. Over time the lip hardens and oil escapes; on a two-stroke, a leak on the crankshaft side upsets the carburation.
