I went through the same exercise. Found 15mm was too fast and 10mm was too slow. 13mm turned at the same rate as stock. Amazing to me how such tiny changes make a big difference.
DD, I have to be totally honest. I stole the idea of 13mm from you, after you posted about it. I was not real happy with 15mm and your setting worked great. Thanks.. ::025::

I have never ridden on a track or on a sport bike and we do not have a lot of really twisty roads around here, but everything I was reading about the SupaT was that it was laid-back and sluggish due to the head geometry. With this in mind when I lowered my SupaT rear by 1" I went hard on the front. I dropped the tubes as much as possible - 16-17 mm and then backed the preload all the way off to drop the head even more. This also served to keep the bike low as I only have a 28 5/8" inseam on a good day when I am bragging about how tall I am. The bike feels fine on black top set up like this, rolls in nicely and holds a line well. It will be interesting to get K60's on it and get out on some dirt once the snow is gone ::26:: ::26::

Glad it worked for you. My wife loves the way the bike handles compared to her old lowered Wee Strom.

Re: Lowering Links

I have a build date for a Renanzco seat this NOV, I am a little worried that I wont be able to touch the ground afterwards. It is gonna be raised about 1 full inch, I am a 30 inch inseem as well.

Re: Lowering Links

I too have found my legs too short after I had a Russell seat built for. I ordered Tabasco's lowering links and can't wait to install them. Just remember that when U do this it changes the mechanic of the shock as a longer linkage as more leverage and reduces the spring preload, so U will have to put more preload in the shock to get your sag back to way it was before.

Re: Lowering Links

I found 13mm works well along with Jaxons 1" link also had the Russell seat mod but asked them to do mine in thier sport style wich keeps your seat height very close to stock and had the pillon done in the full day long style both the wife and I are loving these seats, the folks at Russell are awsome to work with and do real nice work. I finally got the k60s mounted holy shit what a difference, I love this bike!

Re: Lowering Links

Ok. Installed Jaxon lowering links and lowered forks 13mm. My feeling is that the M/C really handles better now. Frontend turns in better. Just IMHO.

Lowering Links

I too have a 30" inseam. However I don't want to lower my Super T. Perhaps if I rode one of your lowered Super T's I might Chang my mind.
But that being said... Hmmm if your lowering the forks in the triple trees helped that much. I want to figure out how much I should lower it without the rear lowering links.
Got suggestion?

Re: Lowering Links

I have been lowering fronts for a long time, I dont think it changes anything, good or bad. It is easy just loosen the triple clamps and makes sure both side have the same length sticking out the top.

You may want to raise the forks in the trees 4mm to start and see how the bike feels. By raising the forks, the bike will want to drop into the turns easier.
1mm can make a big difference, so I would go slow on the amount of change until you like it. jmho

one can also back the pre-load off to the max and sag the frontend to see how handleing changes. ::017::

Re: Lowering Links

Just installed my lowering links from Jaxson. Raised the forks 13mm (To the top of the fork cap) . Handling seems to be fine. What would one notice if the forks were too high or low? I see guys say 10mm is not enough and 15/17mm is to much? Never lowered a bike before...just want ta know???

Lowering too much causes the steering to be quicker. If you go too far you will find when turning a corner at slower speed the front wheel wants to flop inside the turn. You're actually fighting to keep the bike from turning sharper than you want.

Re: Lowering Links

For those who need a shorter side stand, but don't want to modify the stock unit, soupy's performance (www.soupysperformance.com) makes adjustable side stands for many bikes, including the Super Tenere. They also make adjustable links, so you can modify the drop. I have not personally used their stuff, but have heard it is good kit. Being inseam challenged myself, I use a combo of things (Daytona Boots, lower saddle and suspension links - if necessary), to get a bike comfortable.

Just remember... You don't want to slide the forks up *TOO* high in the clamps, and not because of steering geometry issues. Instead it's because the fork legs begin to taper down to a smaller diameter not too far below the lower triple clamp. Sliding the forks up too much begins to lose you clamping/bearing surface between the lower triple clamp and the fork tube, which can lead to all sorts of problems, from breaking the lower triple clamp or permanently deforming it as you tighten up its clamping bolts, to having the forks twist in the clamps causing front wheel misalignment, etc.

You really don't want to slide the forks up in the clamps much higher than 0.60" (15.24mm) or so. You perhaps can go to ~0.67" (17mm), but that's *PUSHING* it. Given what I've seen of the taper of the fork tube and how it effects the clamping/bearing surface and triple clamp I use the 0.60" (15.24mm) above the upper triple clamp as my personal limit.

BTW, I run the stock rear suspension links, a standard OEM length Penske rear shock, Penske re-valved forks, and currently I have the forks slid up in the clamps 0.50" (12.7mm), though I do this to quicken the steering, not primarily for any lowering benefit. And for the record I have a 29" inseam.

Just FYI... Hope it helps.

Re: Lowering Links

You can start at 10mm and see how it feels to you. If you have lowered 1", I would try 13 mm and see how you like it. Remember 1mm can make a big difference. I have mine lowered..

How is the ground clearance like this :question:

On the OEM shock with stock settings I found clearance very limited, winding a notch of pre-load on helped, but two-up even with full pre-load the bike was decking out way too easily. I would have thought a 10mm drp of hte forks would make the pegs a lot lower to the ground.

I do suspect however your Penske is stiffer sprung like my Wilburs (I have a 150nm spring) and better damping, I have already noticed that even with full sag (no pre-load on shock adjuster = 32mm static sag) the clearance is much better and I was told the new shock would hold the bike much higher during cornering - and I am also running a bit more sag at the front.

May be tempted to drop the forks a few mm to help the steering a little, although I am currently loving the setup as it is and just taking 2mm of sag out of the rear seems to improve steering noticeably - and feels "perfect" - but you never know what perfect is until you have tried other settings - the only thing I do not want to do is end up with limited clearance as it does not matter how well a bike turns in, if it just turns onto the pegs.

Ground clearance is terrific! ::008::

First off, Rasher, let me state I am rather, shall we say "portly", individual... As such when I had the stock suspension I ran the rear shock spring preload *FULL* stiff all the time - *SOLO* as well as two-up. I never liked the front steering feel of the S-10 from day-one with the forks as delivered, level with the top triple clamp, and I especially didn't like it as I dialed up more front spring preload (more about that in a moment). So I started sliding the forks up in the clamps, both to put more weight on the front wheel and steepen the steering head angle, reduce trail, etc. The more I dropped it the better I liked it, but then I got to the 0.60" (15.24mm) limit I mentioned and decided to err back on the side of safety, going back to 0.50" (12.7mm). I left it there for past year and thousands and thousands of miles since.

Now back to the front preload with the stock suspension... I kept cranking it up, too, just like the rear, but finally reached a point where the front suspension action - for me - got really harsh (even with the compression dampening backed off considerably), and the steering started to go limp again, so I never did get it dialed full stiff on the springs up front. Instead I ended up with the front preload just a bit past mid-way.

With the bike set-up as described I rode 20,000+ miles, and yes, I drug hard parts cornering from time to time both directions, but back in my road racing years I learned how to mitigate that pretty easily and simply rode around it. Once I got adjusted to what the bike needed I rarely drug anything, even when really hustling. However, as the miles piled up I did begin to notice the subtle indications of the stock springs sacking out, and slowly some cornering clearance issues would rear their ugly head... That's one of the reasons I finally decided to spring (no pun intended - well, maybe just a little bit... ;) ) for the new Penske rear shock and Eibach spring and the Penske valved forks with new springs.

To spring the bike for my weight Nick at Stoltec had to spec *WAY* stiffer springs, as it should be. I wanted that, and knew from past experience a *HUGE* percentage of the suspension improvement would come from just getting the spring rates correct F&R. Since I have received my upgraded components and got 'em installed I have been dialing in the adjustments to get it as *perfect* as I can. Over the years I have learned this is where most folks don't get the improvements they expect from buying high-quality stuff - they expect them to be perfect out of the box and don't take the time nor effort to twist a few knobs or screws and properly dial things in - and I have been corresponding with Nick to get this *just right*. In fact, I've just spent a few days and over 500 miles dialing both ends in...

As a result I've got not only way *MORE* cornering clearance than ever - even when my S-10 was new - but also much better comfort, control, precision, compliance, bottoming resistance, useful wheel travel, etc., etc. as well as reduced dive under braking, less squat under acceleration, less suspension compression when leaned over, reduced harshness, etc., etc. In other words, *EVERYTHING* about the bike is *BETTER* now - period - and I actually have *MORE* ground and cornering clearance...

Even with the forks still dropped 0.50" (12.7mm) in the triple clamps! :D

I just got back from a 300-mile overnight jaunt, and the suspension is so much better it's almost impossible to adequately describe... However, there is one *MAJOR* drawback, especially as it relates to this thread.

The seat height is significantly increased as to what I had gotten used to as the stock suspension had sacked out. Doesn't matter to me. It was still worth it, and the increased control and more composed ride and steering with the better springing and dampening actually makes the bike easier to handle at walking speeds, so seat height isn't that big an issue. I still even run the stock height seat in the high position even with my short, 29" (73.66cm) legs. :)

Re: Lowering Links

I too had some issues with cornering clearance, no matter how the suspension was adjusted. When I scraped my new RideOnADV skid plate in a right-hander, I contacted Jaxon to see if he could modify my skid plate to give me more clearance. Instead, he sold me a set of raising links and I'm happy. No more scraping hard parts, not even pegs, and the bike handles very well. I have a 30" inseam and the bike is a little tall now, but I can live with it.

A suspension upgrade will come, but I want to wait until I wear out the stock suspenders first. When I do upgrade, I'll probably go back to the stock links.

Even with the rear raised, I may try lowering the front slightly because I have one rather odd handling issue. When riding 2-up, if I don't lean forward when cornering hard to put more weight on the front, the bike will sometimes get a little bit of head shake mid turn. Leaning forward slightly prevents the head shake, but sometimes I get lazy. Perhaps dropping the front a few mm's will help. Right now, the front is pretty much at the top of the forks.
