Homologationspecials exceeding the class displacement limits are excluded. This includes, but not limited toDucati models with SPS, R, and RS designations if they displace greater then 850cc.

  • Up to 850cc two cylinder, liquid cooled, four-stroke
  • Up to 350cc two cylinder, liquid cooled, two-stroke
  • Up to 700cc three cylinder, four-stroke
  • Unlimited displacement two cylinder, air cooled, two valve
  • Unlimited displacement single cylinder


    Suggestion: I would like to add the Ducati 999 (non "R" models) to the list of eligible motorcycles over the 850cc limit. I don't believe the Ducati 999 (non R) presents any significant advantage over the Aprilia RSV1000R of the Ducati Panigale that are currently allowed
