Well tonight i got every thing all tacked together for my mono shock conversion on my tx500 cafe project that is turning more and more into a vintage moto gp bike and less and less like a cafe bike. I did not take any pictures of it all together tonight. next time i head out for a smoke ill get some. but here it is as of last night. i built the swing arm cradle out of 7/8 dom .120 wall. a little on the thick side but i needed strength. Tons and tons of planning went into this thing. I now know more about suspension geometry than i ever hoped to know.

So when the moment of truth came tonight to drop it down off the jack and see if the single showa shock from a 75 cz dirt bike would work with all by its self....... it failed. the suspension design works flawless only problem is the spring rate needs to be doubled. So like i figured i would have to do i need to source a more modern mono shock. So if any one has a mono shock laying around that is 13.5" eye to eye please let me know. I'm watching a few on ebay but i hate spending so much on shipping! Im so glad i checked it before i did any final welding. I may have to change the mounting tabs for the shock depending on what i can find.

Enjoy.:weld:

o yea in these pics the shock is just zip tied into place.

Looks good! I like it! ALLOT

I would think you could snatch a shock from a sport bike that would easily do the trick. Have some boys like Mud measure up his...

Hey thanks again for that shock Bill, as soon as i got home me and my buddy knocked off the old tabs and re tacked them with the new shock in place. This time when the jack was taken down it stayed!!!!! it works perfect. Im heading out to the garage in a bit to finish weld and reinforce the tabs more. I will have new pics up tonight.

Thanks!

Did you weight test that rear shock? With your weight on it and have somebody also push down to simulate a bump.

o yes. i fucked with it for a good hour last night trying to get the tire to hit things, i would jump this bike. i have the pre load set on the lowest setting right now and i have the dampener adjusted way soft and still no issues. im sure once i ride it i will need to play with the adjustments but over all i think its going to work great.

Rrugby... at this point im going black on black with a cream leather pleated seat. but im not married to the black right now but the seat has to be cream.

It's the OEM shock from my FZ, me thinks he will have no worries.

yea its a slightly modified 72 cb360 tank. im not in love with it but it works well to hold all my electronics. i even found a tiny little 4lb battery that fits back there with plenty of room to spare for the other bits. the electric starter is broke like all tx500's and i have no intention of ever using it so i did not need a big battery for starting. I'm used to kicking over my dirt bike and this is even easier to kick.
