X2 Vintage

IHRA2026, T. A closed-list class. The craft must stay stock except where the rules allow otherwise, so anything unlisted is not permitted.

Open questions on this class (2)

Places where the rulebook contradicts itself, or where a figure could not be settled. Nothing in this list is decided, and it sits here rather than in a footnote because it is what you would want before spending money.

  • T.2.3 permits added holes in the crankcase up to 10mm provided they do not penetrate internal surfaces. A hole that does not penetrate an internal surface is a blind hole, and the rule does not say what the allowance is for.
  • T.3.3 requires a replacement fuel tank to come from another personal watercraft and permits a fully aftermarket tank only with Race Director approval. Whether that approval is per event or per season is not stated.

Sections this rulebook does not contain for this class

Confirmed absent by a targeted read rather than merely unnoticed. In a closed-list class an absent article is why a part reads as not permitted; in an open class it is why one reads as open.

  • No forced induction article.

What the rules say (63 parts)

38 permitted outright, 21 answered by our reading of the class rather than by a quoted rule, 0 the rules do not settle. Grouped by the answer, because an open class gives one answer to most questions and printing it once per part would say the same sentence forty times.

Not permitted, not listed in the rulesOur reading, not a rule we can quote at you. This class requires the craft to stay stock except where the rules allow otherwise, and this part is not on the list.
