long travel rear suspension

if you got the time and know how you can run a cr-500 link in the rear. Requires a lot of work from what iv seen.

I think you gotta run a special frame for that.

 

DO a search, there are old, very informative long travel threads all over this site.

well ive been thinkin it over for a while, what if i were to fab up new shock mounts on the frame and swingarm and run like a fox or king 2.0 coilover shock

 

You could do that. It would be a bit of work. The geometry you are given by Yamaha with the swingarm pivot point, is a bit limiting. You would be better off designing a new linkage, which could be tricky. I haven't done one for a Banshee, but from experience on other projects, you need to have some suspension design experience to avoid alot of frustration and several iterations. I suppose what I am trying to say nicely is that if you haven't done it before, it's not easy and you can wind up spending alot of time making turds. On the other hand, doing it is the best way to learn. I just want to lend what I can from experience. It could definitely be a cool project, but if you converted hours spent to dollars, it would be cheaper to buy Elka's setup. I am pretty sure a couple folks on here bought the Elka setup. I still haven't seen pictures and would certainly like to. I will probably end up with it one of these days on my red bike once I get through a few other projects. :thumbsup:

If you can doodle something for me to see, I would be happy to take a look at it. I am not the world's leading suspension expert, but I have done it before and will atleast be able to apply a bit of math to ensure that you haven't created a turd structurally, or kinetically speaking.

 

Gimeeabeer tends to know quite a bit about this sort of thing as well. Pinging him for ideas might be worth your time.

Thanks for the rep Firehead.

 

I wish someone would buy the Elka linkage and CMM it. Then I could just manually machine one. Has anyone tried to modify a stock link? I saw a post on here about it, seems pretty easy. Drill, ream, call it good for a 2 inch boost in travel. Just wish I knew exactly where to do it.

I know you know how to use SolidWorks. You should be able to pick up the important points relative to each other (swingarm pivot, shock mount, linkage pivot location). Then start modeling parts and set up a kinematic animation so that you can simulate the suspension movement. It shouldn't take you more than a week to have something proved out in you spare time. Then learn how to use a CNC mill, and make the thing yourself. The experience you will get will be worth way more than the part you make. I'll volunteer to help you if you need it.

 

Of course I can volunteer one of the Zeiss CMM's at my work if some one wants an exact model of the Elka part. :thumbsup:

HAHA, RIGHT. It took me 30 minutes to make a model of a shot glass. I know nothing about importing points and such.

Measure you bike and figure out where the pivot points are in relation to each other. Then sketch and extrude bars in place of thos pivot points. Then once you understand how the suspension moves you can start jacking around the dimensioins on the different suspension components until you find something you like. :thumbsup:

I plan to try some of this soon. I'm taking AutoCAD and machining ect at the college for work and this very reason. (I'd love nothing more to get to the point where I can design and make my own components).

 

Does anyone know how much the elka linkage is? I haven't bothered to call elka but their prices aren't listed on the site, on ebay they have the linkage and the shock together for something like 11-12 hundred. more then I want to spend right now.

Since you have to buy their shock to work with the linkage, when I was looking at it, it cost about $1300. to my door. :thumbsup:
