Wow, way to go lucky! I think thats the first time you replied to a post that wasnt like 8 pages back. Also
Two shocks, one on each side is balanced and distributes the force equally.
So does one shock in the middle.
If you have one shock and it fails then what?
When have you had a shock catastrophically fail? Come on.

i imagine to change to a mono the easiest way is to find a swingarm that fits like a 88-89 gsxr and add the appropriate shock mounts. The swing arm is longer so your bike will turn even less like a sport bike but anything can be done and anything can be over come with enough machine work or $

Nice bike, i dont know how the rear end would be. Your esentialy putting the load of 2 shocks into one as well as increasing the the amount of force throught leverage. So the shock would have to be pretty stout.
Godfrey went with two shocks in the middle so you have the same dampening and the way the swingarm is braced i guess its close to the same leverage as stock, just in a different direction

Both nice bikes worthy of the inspiration gallery.
