If I have a set of YZ465H 43mm forks in my '79 Honda 250, I can run them legally in EVO, however if I have a set of 43mm YZ250J forks I can't run them legally in EVO coz they are from a bike with a linkage. Stupid in my opinion, but them's the rules. Same thing with engines, as EVO550 has stated you could use an '84 500 Husky engine in anything but not an '82 CR480 engine even though they are just a dirty 30+ year old air cooled engine. How dumb is that? Therefore an EVO ultimate class is not just for big bore hybrid bikes, and free's up the STUPID subrules in EVO. This will allow more people more access to parts and see more bikes on the track without any stress from people "anal" about the current EVO rules. This will be a different class to EVO so there shouldn't be a problem. I do however personally think these type of bikes should already be allowed in EVO following the basic guidelines. Just my opinion though. As for the tapered bar/clickered shocks theory, I hate the things on VMX bikes. You couldn't buy them "back in the day" but it's OK to modernise your VMX bike with these because they are not restricted by the rules. I'd rather see an RC500 replica on the track than an RM400 with tapered bars for sure, but only one is legal. By the way even though there is an RC500 replica in my shed and another one being built, I won't be riding them but would love to see similar bikes on the track. For those of you who disagree, stop sooking, no one says you have to ride the class.
Cheers,
