SV650/1000 parts on a GS1100?

[Guest]

Just picked up a 2001 Suzuki SV650 for my son. I did a quick look with a tape measure and it looks like the front end could practically be a bolt up to my 1982 GS1100EZ. I measured the length from the top of the tubes to the center of the axel and the spacing of the triple trees. Don't have exact figures in my head, but maybe off by one or two millimeters if even that. The tubes on the SV650 are huge compared to the GS1100, to say nothing of the brakes. Plus the SV takes conventional handlebars.

Any insight?

It should work out OK
The issues in doing this revolve around redoing the lock stops and having a triple tree stem of the right length.
Of course the fork legs have to be long enough
I summarized some of the fork lengths here:

The other issue is that you need to update the rear end also
Not very complicated but it takes time...

would your son notice if you swapped the front ends without him knowing? heehee

Thanks, guys. I'll do some more careful geometry measurements soon. Need to know tree offset and rake, plus check on bearing sizes. Then I'll need to find a front end and wheels.

Oh, I already have a front end and wheels (as max pointed out! LOL!).

Here's the thread where I mentionned the formula that links offset, rake and wheel diameter

Thanks John. I remember that thread. Good work!

I saw an SV 650 today and measured the fork length.
On it's wheels I recorded 720 mm?
A little short in my opinion...

That is 28.34", my Bandit 1200 unloaded forks measure 30 9/16". I wonder are they the same length between the 650 and 1200?

I would expect so as I believe the frames are identical?
The diameter could be smaller on the 650
This site gives you the lengths of the bare fork legs that is quite usefull when you are doing these kind of comparaisons
