+4 Swingarm

[bansheeryder21]

I just put a +4 swing arm I bought off ebay from the swing arm shop! I noticed when I compress the rear end of the bike, it is a lot softer and may bottom out when I am riding! Has any else had this problem? What do I need to do to stiffen it up or is it going to be okay?

when i went to a longer swingarm i called FAST and he set me up with a spring from eibach for the length and my weight. i think it cost about 100 bucks. it was well worth it..

It's not really a problem, it's reality.

 

It's all a matter of physics as applied to the lever arm of the system. By increasing the length of the arm you push the compressive force (rear axle) out away from the resistive force (the shock), essentially making it easier to compress the shock and spring. So you need to adjust for this with a stiffer spring.

 

It's the same as when you use a longer cheater bar to loosen a nut or bolt.

 

Hope this make sense.

Yeah I understand the concept! The same thing happened when I put an extended swing arm on my 50. that's why it came with an 800lbs spring! I am going to adjust my shock and see how much it will stiffen! It was soft before the swing arm and I don't think it's too much softer! If it comes down to it, I'll just buy a new spring! How many others have a +4 swing arm??? What did you do???

it's best to have the rear shock re-sprung AND revalved for your swingarm length AND rider weight.

 

 

makes one hell of a difference if you get both.

 

I had mine done my TCS, but it's in for service at percision conceptz. Both are reputable companies. But if I was going to do it again I would probably just go with PC.

How much of a difference did you notice after getting your shock reworked? Were you able to go thru woops a lot faster???

I did the Eibach spring and revalve.

Well to really go over the whoops faster you need front suspension as well unless you wheelie over them

 

But yea it pounded the whoops WAY better, it was some of the best money I spent on the banshee. But unfortunately I think my shock has developed a nitrogen leak or something which is why I am servicing it so soon by someone else. The Valving and Spring make a huge difference, I believe all the stock valving garbage is replaced. The rear banshee shock is pretty decent compared to the front suspension. I having it revalved and a new spring sets the shock up for your particular weight. Adding a spring is definately going to help with bottoming out but revalving it will make it nice and plush. Besides if you have been riding on it for more than a couple years it's time to have it serviced anyways.
