Dual Shock into monoshock newb

Hey guys im like brand spankin new to this forum but ive found nothing but tons of help from reading these threads. Anyways i thought i would come here to ask. I have an xj750 and im thinking about doing a little project to get rid of the dual shocks and install a monoshock system. Im looking for a cafe/fighter style I found a picture and a video of the perfect bike. I just need your thoughts on this. Is it possible with a 750? (the bike in the picture is a 550)

Looks like a 80s motor in a 90s frame with a 70s tank.

 

ANYthing is "possible." It all depends on how much cutting and fabricating you want to do.

The bike in the pic above is, as you said, an XJ550 which is a chain driven bike. Makes this type of thing much easier; the conversion in the pic is essentially a "bolt on" as he's used a monoshock swingarm from another bike that came with one, and probably a Yamaha. The only real fabricating would have been the upper shock mount.

A shaft driven bike such as yours would present a whole new and different set of challenges.

 

you are going to have a really hard time doing it. Like fitz says it can be done with lots of fabrication because of the shaft drive. The only possibility i could see would possibly early 80s shaft drive virago swing arm. I am not sure about the length of it or how wide the mounting is. You could fabricate your existing swing arm but it is going to take lots of work to get the angle correct and correct shock length ect.
Call me old school that bike looks neat i see bikes with no seats like that a lot. I don't get the functionality of it. I remember as a kid driving a minibike without a seat i couldn't take it then now 40 years later gives me chills. I just don't get having a nice looking bike if you can't drive it more then a few miles. For those old enough to remember the 60s and 70s bikes some of them had vinyl covered bricks for seats numbness set in after 10 miles imagine these. Go sterile after a 30 mile ride .

 

The bike shown above uses the orignal XJ550 swingarm with the top half made up & welded onto it. The shock is from a Yamaha R6. Tank from a Kawasaki Z1000.
I read this on comments left by the owner on youtube. Think it was his dad that made the top half up.
I have also done a similar mod to my XJ550 as can be seen on my thread but I used the top half of XT550 swingarm & RD/RZ 250 rear shock instead of an R6 shock.
Personally I can't see the problem with doing a similar thing to a shaftie as all your doing is replacing where the shocks bolt onto the swingarm with a couple of bars that then bolt to a shock??? Simple explantion there :lol:
If you can weld it should be easily done as long as there is a suitable place to mount the top of the shock to the frame. I used 5mm plate to make a suitable mounting.
Hope this helps.

Cheers
