Hi Jovian
After discusions today at lakeside it is likely that we will run with a china bike class structure much like you outlined IE: senior up to 125cc, up to 140cc, and a class that is over 140cc unlimited to cater for the 150 and 160cc bikes.
I would guess we will run some seperate junior classes as well, probably 125cc and 140cc that grid up together with a staggred start.
There has been discusions to run a Jap class sperate for jap bikes, the other option is to fit them into other china classes depending on their potential lap times, This will likely be detrmind on the day on an individual bassis IE: big bux high potential jap's will probably go in 140cc+ class.
With the numbers we have been geting at lakeside so far it is likely that next year we can support 3 or 4 senior classes and 2 junior classes
