86 250r durablue swingarm question.

[Jason125m]

I just picked up an 86 R, it has a durablue swingarm on it..
I can tell it is a durablue because of the sticker, but i've never seen another one like it?
Anyone know anything about it? What type of riding it is made for? How much longer then stock? Etc.

P.s, I don't have the R in my garage yet to take a good picture.

I was starting to doubt it was a durablue because every other durablue i've seen looks nothing like this one. Anyone have any idea what it is?
