J arm to A arm conversion

[NYrider631]

Considering this conversion, I ride a lot of trails and street. Im a decent mechanic. are J arms truly THAT bad? and would it be better to just get a new frame or do the conversion depending on how tough it is to do.

who said J arm was bad?

they tend to chew thru the upper arm bushings a bit faster than an a-arm, but thats not a huge deal.

I hear they bend and break easily which didn't make much sense to me but Yamaha did stop using j arms and went to a arms so I just went with the rumors haha

J arm bikes have a lower street value because of the perceived weakness. I have come down nose first so hard in the sand, with a J arm bike, that I should be paralized, and I didn't bend a J arm. I've seen plenty of bent stock upper A arms, J arms, and frames. Hit a tree hard enough and somethings gonna bend.

 

If you wanna convert it, find someone with a junk A arm frame, cut out the angled tube with the rear A arm bracket, and weld it in.

unless you wanted to make it wide I would just use the j arm frame and arms as is
