My two cents as a HEAVEN member,
I believe that Pre 90 will happen as a natural progression of the sport but as to when, I am unsure of that. One thing for sure is that when the majority of HEAVEN members decide that they want Pre 90 in the club as a class to "race", then it will become reality. At the moment (from what I observe), there are approx 8-10 members who have a wish to see Pre 90 added to the HEAVEN race program. Let's not forget that Pre 90 bikes can be ridden all day on the Saturday's that the club has rec riding.
The members asking for Pre 90 equate to approx 5% of the club membership.
The other issue is if Pre 90 is introduced, what would the race program be? HEAVEN already has a packed race program for race days. What class would loose out to make way for Pre 90?
As Shoey has said on other posts, if the people wanting Pre 90 put together a plan for how it could happen and then present this to all the members, then this I believe would be the first step to gaining some momentum for the Pre 90 movement.
Personally, I am happy to ride the current classes available, but having said that, when Pre 90 does eventuate, then I will probably buy a Pre 90 bike to ride as well. Reason, era that I grew up, raced and would give me two extra rides at a race day. Truth be told, I already am looking for the bike that I have picked for Pre 90 ( Honda XR600 ) and when I find the right one, I shall buy it regardless of whther or not Pre 90 is in the HEAVEN race program or not.
Just my thoughts.
