There is no confusion. Just people with their own agenda. The agenda we are discussing is riding one bike in two or more classes. It really is a given that an mc490 is an evo bike. Then because the rule book doesn't dot the I's and cross the T's, its also a pre 85 bike. Then some people want to take advantage of that.
What era are you trying to recreate?
For me and i think for the people that wrote the rules, having bikes that look the same and are as equal as possible in performance, both suspension and technology.
Motomaniac i agree that an evo twin shock bike is more than capable in pre 85. It doesn't bother me putting twin shock and single shock bikes together.
Ballard has done it the smart way for the nats and entered 2 different twin shock maico's, 1 for evo and 1 for pre 85. Can't see anything wrong with doing that going by the rule book.
I personally have a small problem with that. But its just a niggle, not 'the sky is falling ' type of thing.
So do the people that want to ride one bike only have one RACE bike ( not a bike that sits in the shed collecting dust), as i am really wondering why this is. Are you guys too tight to buy a second bike?
