This is a new exhaust pipe gasket for a 1970-76 Kawasaki G4TR, G31M, and KV100.  May fit other years and models.  These are original parts and NOT a reproduction.  These are in great shape (these are thick gaskets).  See photos for condition.  Came out of an old motorcycle shop that was closing after 45 years of business.  Great part for your vintage Kawasaki.  Please email if you have any questions.
