fork and shock lowering
« on: July 06, 2011, 10:17:09 PM »
Anyone have a suggestion of who can lower my shocks and forks ?  I'm also trying to find someone to maybe clean my carbs.

Thanks

because I have an extra set sitting in my garage and thought I would like the look.  I will obviously keep the originals shocks and forks as my bike is completely original.  I thought of doing it myself but could not find a good tutorial.  No need to tell me the best, safest ride for most types of riding is stock -just wanted a more aggressive look now and than but be able to turn it back to stock with my originals when desired.

Thanks,
John

Unless you are vertically challenged or really wish to destroy the handling characteristics of your perfectly set-up from the factory stock bike, I would caution against it.
Your bike looks great as is, find something horrible to lower. ;D
I think the thing I most like about motorcycling is the speed at which my brain must process information at to avoid the numb skulls who are eating pies, playing the ukulele, applying make-up etc in the comfort of their airconditioned armchairs as they make random attempts to kill me!!!!!!!

If you must, lowering your bike requires this:

For the rear, either purchasing shorter rear shocks, moving the top mounting points forward, or both. You could use lowering blocks, but those are wonkey.

For the front, either just move the tubes up in the triple tree, or purchase shorter stanchion tubes and order custom springs from like, hagon, or works, or something like that. Come to think of it, a 550 front end would work, with 550 springs. Should be able to fit the 750 front wheel to them, if you just throw the 550 forks into the 750 triples.
No.

I used shorty's from DCC on the rear end and lowered the front 10mm be moving the fork tubes up in the triples.  Be careful how much you lower front end as it can lead to head shake.  I had to loose the center stand but nothing else rubs.  I haven't noticed any loss of handling at speed and prefer the lower ride height at slower speeds since I am vertically challenged and prefer to be able to reach the ground flat footed.

Oh, it's not a 750. It's a 500.

Scratch the part about using 550 forks on your 750, then...
No.

Thanks to those who suggested where  / how to lower my bike.  for clarification, the bike I am considering to lower is a 1973 cb750.  The pic I have posted on the forum is of my 1973 CB500.

My thought is that I will most likely slide the fork tubes up about 3/4 of an inch and just change the adjustment on my rear shocks.  i did this on my 500 and I really don't notice a handling difference and it seems to just sit a bit nicer.

Thanks,

John

Oh, then yeah, like I said, 500/550 forks will work. Just order some decent shocks that are shorter.

I still advise against it as a practice, though.
No.

The adjustment on the shocks is for pre-load, not height.  If you adjust them to the lowest setting so the bike sits lower with your weight on it you'll lose most of the travel and will bottom out much more easily, which could prove dangerous.
