ATHENA Engine Oil Seal Kit for YAMAHA TTR 125 2005-2015

On YAMAHA TTR 125 from 2005 to 2015, the ATHENA P400485400157 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.
