IHRO classes 2010 and beyond
Posted in IHRO News, Technical | Comments Off
Following response to the suggestions I posted for the future of IHRO racing classes I have decided to adopt the following, starting from 2010.
There will be 2 classes called IHRO 1 and IHRO 2.
The IHRO 1 class will be for single cylinder machines and will not have any rule changes from what is currently in force, there will be the current capacity class awards for 250, 350 and 500 machines, this will, I hope, make for a full grid which always looks better. Although I do realise that there are some single cylinder machine riders who would loose their second ride, IHRO 2 will allow all IHRO 1 class machines to compete as well, this would ensure fuller grids at the start of this new venture. Hopefully the single cylinder only class might encourage people who claim to have left the existing class because of multi cylinder domination to return, or was that just hot air?!.
It will not be permitted for riders to compete in both classes with the same machine, we need to establish both classes in their own right
IHRO 2 will be for multicylinder machines which will be open to allow any 500cc Grand Prix machine up to 1972. Until this class is established, there will be only one set of awards, no different capacity classes, this may well of course change as the class develops. This class obviously allows in two stroke twins and multis but we will make it the same for acceptance of machines, GP machines or good replicas only, not just a road T500 with a fairing and expansion boxes, it would have to be a good replica of a TR500. The class would allow aircooled, twin shock, drum braked machines only, if you look at what was running in the GPs in 1972, that would certainly cover most of the bikes out there, there would be odd exceptions such as the Konig but IHRO has always had an exception policy for worthwhile machines, this will continue to apply in this class. The essential thing is that they would have to be machines which genuinely raced in GPs as with the current class eligibility rules. The class bikes could be Paton, Honda 450 (any chassis used in a GP or accurate copy of it) , MV 3/4 cylinder replicas, TR2, TR3 real or good replicas, seeley chassis or any that were used at the time. Then you have TR500 Suzukis, any chassis that was used in a GP, Kawasaki 500 3 cylinder, Husqvarnas, Eric Offenstadt even cut a cylinder off a 750 H2R and used that!, it will be a class where people can look at the history books and buy a machine or make a good replica.
I have included a selection of photographs of the acceptable appearance for machines, and also one which I trust will illustrate what is definitely NOT acceptable.
There is a pdf for you to download which contains the regulations that are proposed, I will allow comments for a month on this then I will finalise the regulations to allow people to build machines for next year. I am looking for comments from you that will allow me to avoid any problems that I have not foreseen particularly regarding the dates of construction of machines etc.
I trust that this will allow for fuller grids for the future, but of course, that is up to you, the riders.
