To exclude so many standard bikes is just dumb - I don't think that anyone really thinks that's the slightest bit reasonable, or good for the sport. Mick's suggested alternative is a great idea, but falls down as Graeme M (and others) have pointed out - I think that a lot of the votes for staying with 9" of travel are more a rejection of the problem with 'standard travel' than any love for 9" of travel.
I think the revised rule should be:
All bikes are limited to 9" of travel front and rear, or the standard travel, whichever is greater.
Its the best of both worlds - the guys with the stock YZ250/400s, Maicos, Montesas, etc etc etc can run, while still keeping the class different (in both suspension performance and appearance) to the Evo bikes.
