Alright, here's the whats up with a Hayabusa Rear shock onto a First Generation Bandit (should work the same on the 6 or 12)
First thing to notice is that the Hayabusa shock is 13" eyelet center to eyelet center, whereas the bandit shock is approximatly 11.75" from eyelet center to eyelet center. that is really the only real problem with the fitment. You "could" just compress the shock 1.25" and wedge it in, but that is intstantly giving you 1.25" worth of preload on the shock which you could never adjust out. Now, if you are going to have the shock revalved/sprung you could see if perhaps there is a spring which is 1.25" shorter fully uncompressed, and have them install that onto the shock body in place of the stock spring.
What I wanted to accomplish did not involve either of the two techniques listed above, I wanted to be able to install the shock without having to compress it on instalation, and the whole reason for using the stock Hayabusa shock was to do a relatively inexpensive suspension upgrade, so revalving/springing would sort of defeat the cost saving issue.
What I will be showing, here is done with stock bandit parts that are already on your bike, and the Hayabusa rear shock
Basically all that needed to be done was to clearance a few parts so that the shock lever assembly is allowed to droop further, accepting the longer Hayabusa shock.
Here is the bandit shock lever installed and allowed to fully droop, and you can see how far down the lever has to move in order to fit the Hayabusa shock....
There are 2 areas on the frame that need be be cut/grinded to provide clearance for the Lever to droop further, really its the same location, just on both ears of the lower lever mount area, they are illustrated here...
Here is what It looks like with the frame mount material cut away....
Basically you just need to clearance the frame enough to get 13" from the top shock mount hole center (on the frame) to the bottom shock mount hole center (on the lever), once you are done with that there is one more area that needs to be addressed...
Here you can see the shock to lever clearance issue, even when installed on the lever, the shock is not allowed to pivot forward enough on the lever....
A small amount of grinding here will relieve this problem, basically you need to grind it far enough to allow the lever to touch the spring when the lever is installed on the shock, it will provide the necessary clearance to get the shock bolted up!!! Here is what it should look like....
Here you can see a couple of final clearance pictures, there is no binding on anything and the shock can be installed fully extended...
Here are the Final fit pictures....
Now, there is another way to avoid the cutting/grinding, and that is by dealing with the extra length up at the top shock mount, it could be cut off and extended higher, but that would require pulling apart a lot of the bike, what I have shown in the pictures above could be done by only removing the swingarm for the necessary room to work.
There may be a small amount of inner fender trimming necessary to clear the piggyback resevior, but thats very simple to do, also longer dog bones will be required to return to stock ride height because this mod WILL raise the tail, either you can make them yourself, or buy the lowering links from Holeshot.com
I hope this can help those that are looking up upgrade their first generation bandits, if there are any flaws/questions, your input is greatly appreciated, and may help someone else down the road
Good luck, Josh
