The races are whats pressed on and I haven't done it, but I'm willing to bet that all the X crap can be used in the R neck. When your broke, your broke and no the 200X front end isn't that weak so just give it a go.
Most of the guys with 250R's just flat out crank them on straight aways, they don't jump and use an R to it's potential. I do, and thats why I can't have one again because I end up flying through the air.
Look at the posts titled "rode the R today!!" blah blah blah and about the only thing in the air is the front end. Those would be the people to call a 200X front end suspension weak. Of course a R needs an R front end but IF a 200X will bolt on (of course steering stops would be a plus) I'd go ahead and use whatever you have.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
