Observed Trials Mission Statement

Observed trials is a very significant part of historic motorcycle competition. It began as a wintertime sport for European enthusiasts, who tested themselves by tracing ancient Roman roads. These riders negotiated various obstacles along the way, all of which gave test to both man and machine. As the “gentleman’s sport” developed, such obstacles became more specific, and more challenging. From the 1980s until today, the obstacles presented to trials competitors have been inconceivable for most motorcycle riders.

AHRMA’s observed trials goal is to provide its members a safe, historically accurate environment to showcase and experience vintage machinery. The key to this enjoyment is the observed sections. From the 1950s into the ‘70s, sections were mainly composed of wide-open areas of challenging terrain, with the rider’s choice of line determining his/her success. Observed sections reminiscent of this era are critical in AHRMA’s representation of classic observed trials. With period-accurate sections, machines will remain true to their original concept, and the techniques required to ride them will do the same, enhancing the entire vintage trials scene. The trials-riding experience will undoubtedly result in good friends, good rides and good fun.

Refunds will be issued only to pre-entered riders who have filed a Refund/Credit Request Form with the AHRMA National office. A refund form is in the Handbook, may be obtained from the office, or can be downloaded here. The form may be filed by mail, email, fax, or the office may be telephoned with the relevant information. Please see AHRMA Handbook rule 4.7 for more details.
