Copyright 2003, Roadracing World Publishing, Inc. Rich Munson has resigned as Pirelli Racing Manager for Metzeler North America after about five years in the position. Sources within the company characterized Munson’s resignation as being related to a contract-renewal dispute. Jeff Johnston, who handled racing for Metzeler/Pirelli prior to Munson and who now works in motorcycle tire marketing for the company, will fill Munson’s role at least in the short term. During Munson’s time with Metzeler/Pirelli, the company developed the SuperCorse DOT-labeled racing tire, which has proved very successful at all levels of motorcycle road racing, including winning AMA Superstock Nationals. The tire was sold under both Metzeler and Pirelli brands, and the company’s percentage of U.S. grid fitment increased substantially during Munson’s administration. The company recently concentrated its racing efforts under the Pirelli brand. Attempts to reach Munson for comment were unsuccessful at post time.
