Hi, Im new to the forum and just bought a 1999 600 F4. Ofcourse before I try any kind of stunting with it I want a good cage for it. I was lookin around the net at some and realized I have all the tools nessesary to make my own. But I need some dimensions as to make the "sliders" portion of the cage.

I noticed that all sliders "neck down"? where they mount into the recesses of the frame where the bolts go. How deep are these sections of the sliders for your cages? I noticed some bikes are different for each side.

Im making the slider bar portions of the cage out of 1.5" chromoly steel tubing with a 3/8" wall thickness.(Had a little extra after making suspension links for a rock crawler). And im gonna try to make the cage connect to atleast 3 different places on the frame(not all with this tubing). I know this tubing is a little overkill as far as strength, but too much is better than too little I would think.

If anyone here could help me with this ill be sure to post pics of each step as it goes. Thank you so much ahead of time.

 

Go buy a Atown. He did all the figuring for you already.

 

you are using thick tube on the wrong part of the cage you want it on the down pipe. and make sure if you use the bottom motor mount for a cage mount you dont put a slider in it cause the motor and frame are week there and will break the motor.seen it happen twice now on double slider cages. for your measurements you are gona have do it like the rest of the cage builders cause i no we are not gona just start throwing measurements out there. but use some of the info i gave you and it will be a better cage none the less

 

+1 i even got a new style f4i and 636 cage coming out with add ons

 

Wow. those are nice cages for a really nice price... If making this cage becomes too much of a task for me ill definetly go there. But...

For now I would really like to try and make my own. Sorry im just one of those people that try to find every other design and make it better...(in school for mechanical engineering) Plus its always fun when people ask "Hey, what cage is that?" and you reply "Umm....mine?". I just take pride in stuff like that. If it breaks I can only blame myself and not have to beat myself up shouting obsenities twords the makers of the cage throwing out negative reviews. Ok...ill beat myself up either way, but just myself! lol.

I dont expect anyone to unbolt their cage and take a measurement. Im just sayin that if you got a set of sliders/cage lying around, bent, broken, new, and wouldnt mind breakin out a set of calipers or ruler then you would make me very happy. Thanks again.

 

totally understandable this is how i got started making cages

 

I'm a fabricator by trade and have built a few cages. Actually, when I first decided to go to school for fab it was with the intention of getting into the biz of building cages and such. You just have to tear into it and see what works and what doesn't. Your best friend will be a set of calipers and an angle finder of some sort, even if its just a simple protractor. Just start cutting and building. It's a lot of trial and error your first few times. Just know that you may end up building a few cages before you find one that works. Oh, and save that chromoly for something else. Its way overkill for this.

 

Cool, thanks a lot guys. Guess ill make it a several weekend project. Just dumped snow here so I wont be tempted to go ride instead of tear into it lol. Either way if anyone has anymore helpful tips like Atown ill be sure to keep checking the forum.

 

Can anyone tell me the length of the stock bolts where the sliders attach? I just lathed them all out but forgot to measure the stock bolts before I went to work today lol. I have 1.5" of bolt hole in the slider. Im assuming one(bolt) is approx. 10mm longer than the other and the bolt is a M10 x 1.25. I live in the mountains and was trying to run to CD Fasteners when I get off so i dont have to run home first(40 min drive each way). Thanks again!

 

Oh, and is it crucial that each bolt be of perfect length? Will it bottom out or hit anything if its 5-10mm too long on either side?

 

if they are too long just put some washers on the bolts to take out the extra... and yes if they bottom out it could cause stuff to break... my lil bro-a.k.a. A2K!! had this problem on his r6 where the right bolt goes into the frame/head and cracked 2 heads cuz the bolt was bottomed out in the head...
