Interesting that the question is basically about a Buell. May I add a humble question/comment. Last year at the BUB meet a Buell XBRR which is a factory built formula racer ( I believe only 50 were made for certain teams), was allowed to run in a Modified /Production Pushrod class. Could that happen at ECTA ? The way I read the rules from both organizations, I would say no. as per ECTA -( This class does NOT include factory produced road racing or any other "works" racing models". Very similar to the BUB/AMA rule.- As per BUB - AMA (Overall construction of the modified frame must be based on the original "production" design and geometry and NOT PURPOSE built.) So where does the actual definition of "production" come into play? Everything is "produced", it doesn't just appear. To me, a production classed machine should be one thats mass produced and available to the general riding public. The XBRR was never mass produced for the general public consumption with only 50 made and sold to specific Formula dealer/teams, yet was allowed to compete in a M/PP 1350 class. Much to my objection I must add.
I'd love to have some feed back from Scott, Todd, John, and whoever has an opinion on this XBRR. Should it be allowed in "Production" classes when in reality it was a special purpose built Formula racing machine with only 50 manufactured.
