Tentative... the discussion is open.

• Open Class: all vehicles with any number of wheels and any kind of fairing
  
• Partly Faired (PF): all vehicles either front or rear fairing
  
• Unfaired (UF): all vehicles with no fairing
  
• Trikes (3W): three-wheeled vehicles with no fairing
• Tandems (TN): on back-to-back tandems fairing between riders is allowed
  

NOTES:

• Disc wheels are allowed for all categories and for any wheel
  
• Even though the use of a different vehicle is allowed for each race, only scores achieved with the registered vehicle or with a less-performing vehicle (for that race) will be accounted for the general ranking.

For each vehicle category, prizes will be given for the following categories*:

• Women ?18
• Men ?18
• Women Over 50
• Men Over 50
  
• Junior (14-17)
• Under 14 (50 m drag race only) - no need for pre-registration, free of charge.

* Further categories could be added after registrations are completed, within organizational constraints and with a minimum of 10 participants for each category.
