Ah, the infamous ISDT/E five-minute tire changes. For those of you unfamiliar with this aspect of motorcycling, ISDT/E stands for International Six Days Trial (now Enduro). Often referred to as the Olympics of motorcycling, the events are six consecutive days of off-road competition, in which teams of riders representing their home countries compete for bronze, silver, and gold medals.
In order to assure the best performance possible from their machines throughout the week-long competition, riders repeatedly install fresh tires. However, ISDT/E rules require not only that the rider alone must performance all maintenance on his or her machine, but also that they do so within just a brief work period at the beginning or end of each day’s competition. As a result, riders must be capable of changing tires in just a few minutes.
How do they do it? Practice, for one thing. Plus, a few rearrangements to the motorcycle. Notice for example that this Italian rider’s Sachs is equipped with a center stand. Also, ISDT-prepped motorcycles feature condensed components to simplify wheel removal/re-installation. Plus, rim locks are typically dispensed with, relying instead on dimples or roughened edges on the inside of the rim to prevent the tire from rotating. Other tricks include shaving down one side of the rim for less overlap. Whatever these means employed, the bottom line is that each and every ISDT/E rider is exceptionally skilled - not only in their riding capabilities, but in bike prep and maintenance, as well.
