Hirth 515
Any engine experts out there? I can't find anything on the Hirth 515 in JAWA38 or JAWA42. These two sources take the Hirth type numbers to 512, a much more powerful engine.TSRL (talk) 10:24, 15 January 2009 (UTC)


 * I have just found an article on it in the German WikiP!TSRL (talk) 14:12, 15 January 2009 (UTC)

Does anyone know if these records were homologated? A ref would be good.TSRL (talk) 14:35, 15 January 2009 (UTC)
