At first I agreed with you but thinking positively, I think the cost for a 600/1000 is at least twice that of a little twin so hopefully the cost won't be as high.
Other than the normal or travel and such...
To get the OEMs to potentially support, get the new models seen (eg. The KTM)... No clue for sure but I assume they don't want an '01 SV out here when the 2018 is available and Suzuki wants to sell bikes.
The travel and all that and spec tires will keep the costs up. Nowhere near like a 600/1000 of course but still enough that a lot of club level riders will go chase it to call themselves pro and spend their entire budget on doing it. Can't blame them.
Like I said, I totally get it and agree with it from the MA perspective. I think its a good move for them. Even though I know it will have some effect on our grids. I'm not saying it'll kill us or even hurt us severely or the like, it'll just have an effect. Longer term it may help the LW twins as there will be some cool stuff available every year if the OEM's get involved in the class.
I'm also hoping we'll be able to figure out some things and work with them to make a more linear progression to pro that will work well for the long term of the sport. It's been great working with them on our few events this year. They're good people and truly are looking at the long term good for everyone.
