Now lets talk about buying a record.
Any competitor who runs within a class that they are (should) be legal for and sets a record, I will always give them cudos for achievement. Anybody who sets a record on pavement in which their bikes fits the engine displacement and frame class is an outstanding achievement. You have worked for that record, and maybe somebody had a previous record in that class. And you broke it. Well done.
In my opinion if you take a 350cc bike (for example) and jump into all the other engine classes then you are buying a record.(jumping into higher displacement classes, with same engine). There is no other reason to do it other then to put your name in the book some more or get more records (assuming you did not change engine size). Would it not mean more if you tweaked your tune, changed your fairing and bettered your speed. Is it about speed? or is it about getting your name in the book as much as you can with one bike?
No issues with anyone going from lets say 350cc bike in A-G, A-F, APS-F, APS-G, MPS-F or MPS-G. All in the 350cc class. You get what I am saying.
I could see a financial issue from the ECTA with removing this rule, as each class change up gets more money for the organization.
