I got an 07' gs and I'm pretty much tip toed on it. Would it be a good decision to lower the bike about an inch or two?
You have to do the things you don't want to do in order to do the things you want to do.

I lowered mine about that amount and like it this way.  Wasn't a tip toe problem for me, more to get my ancient arthritic hip up over the saddle.

I just put a Katana rear shock on mine today, and now I am truly tip toed on it, and that's with a seat mod! Before I could flat foot on the left at a stop on a crowned road. Now I don't want to take it out til I lower it again, because if I put my foot in a hole I'd possibly be in big trouble. So you could mod the seat. My PO lifted the cover and reshaped the foam up front to make a lower level pocket which is actually comfortable, and there was someone looking for a stock seat that had a modded seat who wants to do a straight swap, I believe, in the For Sale/Wanted to buy forum, maybe go dig through that?

Or replace the stock links with lowering links, just get good ones. I'm ordering lowering links tonight, I think the Diamonds. I measured from my heel down, it's four inches to the ground. The Diamonds have 2 or 4 inch settings
http://www.diamondpowersports.com/lowerlinks.php
You can also find them on eBay a bit cheaper.

Muzzy makes a nice billet aluminum anodized link that I think would look nice with the front rotor, not that you'd see much of the links. Here the ZX6R links are the same as the GS's. They are 1 1/4 to 2 1/2 inches.
http://www.muzzys.com/catalog/chassis.html#links

If you lower the rear a lot you may want to lower the front end as well to keep the geometry closer to stock, as it will change the rake and trail, and the steering response. Then you will need risers to get some room, as the top of the fork tubes only have about 1/2 inch to come up before they hit the bars. So with that in mind, check the wiki for options.

I'd like the Motechs, but I have already spent too much on this moto for the moment, and am contemplating spending more that I don't have yet, so they will have to wait. I'm going to try the junkyard option. I did give in a year ago and put both a riser stem and a new riser bar on my mountain bike. I think it ruined the look of my Specialized Stumpjumper (fully suspended, disc brakes, mmm!) but it's a lot more comfortable to ride, and a bit less easy to do a face plant when downhilling.   8)


gsJack, you lowered your forks as well, yes?

I lowered the front only about 1/2" and then put it back up because I wanted more lean on the stand.  So I'm about 1/2" up in the front due to the taller tire and about 1" lowered in the rear net.

The Diamond links have 2 holes, one for standard height and one for 2" lower.  The Muzzys ZX6 links lower about 2 1/2" using the 2nd hole, first hole gives about standard height.

So my current change in attitude of about 1 1/2" gives about 1.5 degrees more rake.  Works for me.  Way back when I put a 130/90 rear on which raises the rear about 1" it gave about 1 degrees less rake.  That was noticeably quicker.   :laugh:  GS500 has about 25* rake and Ninja 500 has about 27* rake standard according to specs.

Muzzy would NOT sell me links for a ZX6R. I suppose because I was dumb enough to call them and ask them about them!  :cookoo:  I could have gone back in and ordered them later, but they said the would NOT support any problems or take any responsibility for links for one bike used on another.   :dunno_white:

Diamond however gave me excellent customer service, the tech compared them side to side, said sure, it'll be fine. He told me to order the parts as KAW 6-9-12, basically the version for the older Ninjas. Their GS links only have two holes, for stock and 2" lower. The difference total in length was like 1/2 inch. They also use the stronger (?) aluminum. The tech told me you could actually run this bike on ONE link, and it properly tightened, it would support the weight without risk of failure...   8)

I'm crossing fingers these get my rear back in the saddle ASAP.

Hallelujah!
I got the Diamond links a couple days ago, got them installed tonight with my best buddy working from one side and me the other.
I took a pic of the stock link and the Diamond links, which are for an early ZX6  (ordered as stated above, for a KAW6-9-12).



We put it on the bottom hole first, it was quite dramatic! Didn't cinch anything up, just looked at it, my plate was pretty close the the rear wheel. It looked like the 4" that it would have lowered a ZX. So we put it on the middle link and tightened her up.



This setting took my seat height, which was at 30" from the lowest part (seat is modded in the foam up front) to 28", which is perfect, at least to me to let me totally flat foot it. I have not ridden it yet. Top edge of the tail piece was at 37 1/2 ", came down to 34 1/4". This is with a Katana 600 rear shock newly installed, which is what necessitated lowering the bike so I could ride it, as I was really on the tips of my toes after that mod. I could have ridden it, but it was that we do so much stopping in traffic on crappy pavement and in rough dirt on the sides of canyons that it made me want more leverage for safety's sake. It would not have been a problem on a track (not that I'm likely to get to ever ride on a track). Plus is I can maneuver it now when parking it, without having to get off and push it around. Try pushing a heavy bike on your toes (with bad knees)! The fork tubes have been slid up to the handlebars, to help offset that my rake and trail is now affected, I'm not sure how it will feel to me, I know it will slow the steering response. I'm pretty sensitive to cockpit changes and front end angles on two wheelers, and I liked it fine stock, so I may  need to experiment with lowering the front end a bit more via risers to get a more stock angle, though if it was okay with gsJack it's probably going to be fine with me. I did really appreciate the quick response in the front end with it stock though. I didn't have any problem with my side stand, it's fine. The center stand however is very much harder to get the bike up on it, and it's squirrely. The bottom of the seat frame is closer to the back tire, my plate needs to be relocated higher. A little less ground clearance so I'll be scraping pegs sooner.   :icon_mrgreen:

Here's a side stand angle view



Here's a clearance view with a 150 pound, 6' tall guy on it. Note the clearance between the rear tire and the plate. I'm a little concerned about the center stand clearance, but I'm used to dual sports.


Because the front end is a bit higher now, I have just a touch more bend in my elbows and can cover the front brake a lot better. I'm just a bit more upright too. I'm anxious to get it out for a run tomorrow. Next up is a rejet, K&N lunchbox filter and a new can. Soon as there's some extra money, c'mon refund!

Thanks for the input Teek, it's all adding up better now.   :thumb:  Your Diamond ZX6-9-12 links are about 1/8" shorter than the Muzzys ZX6 links which were reported to have lowered the GS about 2 1/2" when using the 2nd hole.  With the approx 5:1 ratio that's close enough since you got approx 2" lower.

I took your pic to Paint and measured your links and got 6 15/16, 7 1/2, and 8 1/16" center distances for the 3 holes.  Good data to save for future ref, other inquiring minds will want to know.   :)

That's a nice amount of lean you have on the center stand, you should be able to lower the front 1/2-1" without trouble.  I've been thinking of going back and lowering my front again soon.  Not sure how far I can go but will check it when I can, we are having blizzard like conditions here today.

YOU deserve your POS carbs!!!    :icon_mrgreen:



The half inch down on the front end is fine. Bike seems just a bit slower in the turn response but it was probably more me a little worried about how low the back of the center stand was. I could see hitting a reverse camber curve leaned over and dragging it (at least in my slightly paranoid imagination    :oops: ). The links were hitting the stand 1/3 from the top, so the stand was an inch from the stopper, we took it off and I feel better now. If we had turned the links around, it seemed there was not enough clearance to the swingarm on the bike's left side. It's more cramped than on the right.

Moved the plate up and angled it out on some simple jury rigged brackets. Plenty of clearance now.
Also, the side stand IS too tall depending on the degree of level of the parking area. If I turn it around the other way in the picture, I'd be afraid of a strong breeze pushing it over. Discovered that after I got home. It was fine however at the gas station and several dirt pullouts.
The Katana is a hard riding bastard, the bike has no cush between that and the Sonics up front. I'll play with the adjustment a bit, then may swap springs with the GS stock shock, still leaking in the garage, and reset the preload up front by changing the spacers. Man it's nice to be off of my toes though! Especially in dense traffic.
Next time out I'll go back to leaning it over more, I think the Katana in the back has evened out the handling.

I used the first hole on my Pingel links to lower about 1 1/4 inches and had the same problem with them hitting the ctr stand so I turned them over.  The two extra holes are sticking up on top and have not been a problem, plenty of clearance.

Hi gsJack,

Thanks for the info!
We'll put the center stand back on to take the rear shock out when and if it comes to that to swap springs, and then try turning the links around again while it's up, just to see. It wasn't clearance to above, it was behind and to the side, looked like it would rub. Otherwise the bike is cleaner with the stand off, squirrely now on it, like you could give it a spin. My buddy really lays the bike over a lot more than I do, he's getting into knee dragging now, I think, when he takes the GS out. He's kinda liking riding it. He likes to drag his toe currently on his DR, which has huge clearance. We ride a lot of shifty pavement. Hit a big hole today that had a manhole in the center on PCH that I have hit way too many times and so watch for it now, today gave it wide berth, but the DR went right over it. Me, with my new low rider race bike ( :laugh:) it coulda grabbed something, that center stand felt like a loose grappling hook under there.

Hey --

I got 1 1/4 inch lowering links off of Ebay, they look to be pretty good. I was a bit worried as I didn't want to have to modify the kickstand, but it still has plenty of lean AND BONUS now I can toe on both sides!  The  only thing we had to do was dremel off the paint inside the holes on the links as that minute layer made them too tight to install.


Have fun with it... i LOVE my naked lowered 07 and may even have a seat soon to play with :)

i got a 2 inch lower on mine heres the pic of it. the links were like 34.00 on ebay and the have gs500 engraved on the http://gstwins.com/photogallery/displayimage.php?album=lastup&cat=0&pos=31

Has anyone ever broken those links? It gets me worried because of all the stress those go through because of the leverage. They are originally steel and in engineering everyone knows never replace a steel unit directly with an aluminum one because the aluminum will be a third to half as strong as steel. Plus the amount of material between each hole makes me worry, these are after all what connects your swing arm to your shock.

Teek

I asked the guy at Diamond about that, and was told the type of billet they use is extremely strong, and that the bike would be safe with ONE link! I think there has to be some BS in there, but they claim they use the latest strongest aluminum.
gsJack has been riding on links for 10s of thousands of miles, he's a solid middleweight, and he hasn't broken any yet, have you Jack??  ;)

That looks like about 4 inches lower, wow! Maybe it's the fairings, and a stock rear shock that makes it look so low. I like the paint.  8)

the thing about the stress on them is they are getting pulled not pushed. they have little to no stress actually put on them. thats what the shock is for.

How tall are you folks that are lowering your bike. I'm just curious because I'm 5'8" and can flat foot my '04 with no problems. How can I tell if my bike has already been lowered? By looking at pics I don't think it has because there is quite a bit of space between the tire and the rear plastic!

just curious not trying to be mena or anything!
