Indeed YZF did start in 93 but the Bandit was much later too. I think it shows a lack of understanding more than anything.
Another rider said the worst thing you can do is ask. If you think it's eligible, then get your facts in order and enter. You only have a problem if someone protests and "if" the organiser decides the pursue the matter, then you put forward your case. Given what else is being entered, are they really likely to exclude anyone?
