there is really not that much difference but a few pounds. I think its more of a preference thing.I mihgt be wrong there will be some people that can chime in

alot of people say they handle alot different, as far as durability i think the a arms are stronger, but main thing i hear is that if you break a j arm or get aftermarket ones is that they are a TON more expensive. this is just what i have heard i have rode one j arm and thought it was fine. but the way i look at it if you got a sawzall and a welder you can do anything. my next project i am going to put a set of suzuki ltr 450 a arms on a banshee j arm frame. if there is a will there is a way

J Arm are a favorite of the drag race crowd because they are in fact a few pounds (if that) lighter.

J Arms from the yamaha factory are not as strong as the AArm bikes.

However, several companies can make you aftermarket J arms that will do you just fine.

 

The question is what do you plan on doing with your bike?

 

Tim @ Stellar does some of the nicest AND most unique work I've ever seen...

Keep in mind, if you are using factory J Arms they are at least 20 years old if not older...they were only made from 87-89.

I am wanting to use for dune riding mostly.

If they are factory A Arms (big, ugly, flat looking with a NON-replaceable ball joint), have someone make you aftermarket arms.

As said, I wouldn't trust a 20 plus year old part.

 

A properly built aftermarket J Arm is every bit as strong as an A Arm...and lighter.

factory j arms are very hard to come by nowadays. look into stellar j arms with replaceable ball joints.

if i recall LRD racing out of oregon made a kit for the j arm frame to replace it i think they were called D arms that were supposed to be VERY nice

No, LRD never made D arms, that was either JP Racind or Lonestar Racing which bought out JP Racing when they were going bankrupt for the second time.

I ve heard J-arm frames have a bad rap for bent arms and bushing wear.I have a J-arm and i like it, i dont see my self jumping 20 feet in there eithier .

Lonestar made/offered aftermarket J-arms at one time which were more of a D-arm as everyone is speaking of. I bought a set a long time ago but never ended up using them.

 

IMO they felt a bit heavy but were stout in every which way as far as design. They are discontinued, have not ever seen a set since I sold the ones I had.

 

Tim @ Stellar does make some nice looking J-Arms.
