OK I had to do something with my front end, just too soft & mushy for me, but before investing for a high dollar fork cartridge kit, I decided to see what I could do with the stock fork first.

I did find out that the stock springs for the 08's & std 09's are 0.65 too soft for my weight, 225lbs+ :rolleyes:

So I contacted Lindemann Engineering, new (owner Ed Sorbal) at 408-371-6151 and commissioned him to make me a set of custom springs to my spec, basically the springs I had made are perfect "drop-ins" with stock dimensions but with a spring rate of 0.85 cost of the springs are $175.

I used Golden Spectrol 7.5w fork oil (stock) and set the air gap level at 120mm with the forks collapsed.

Now with 2 track-days on the newly sprung front end, guess what? their not bad at all, really good in fact, with the help of the track suspension specialist (at the track) I got the suspension front & back dialed in, and can now say that its never felt better.

I did trade bikes with Ben (mental999) for a track session at Laguna Seca, his Hyper has the Ohlins cartridge fork kit, and while his forks worked good, but for me, not necessarily better than mine, so at this time I will not be rushing out and getting a fork kit any time soon. Thank goodness. :rolleyes:

Moral of this story? try making the stock stuff work for you first, you might be surprised & save some some money! :D Aloha Alex

Hello Alex,

thanks for sharing your findings. You didn´t say what model you had, is it an S with Marzocchi forks or base model with Kayabas?

What sag numbers have you been using for static and race sag?

We usually use 5mm static in the back and around 25-30mm race sag in the rear.

The forks are being dialed in at 1/3 of the travel race sag, forgot about the static sag. But that is coming from the Superbikes.

I'll answer for him. He has a 2008 "S" with the Marzocchi forks. However, even the 2008 standard had Marzocchis. It wasn't until 2009 that they used the Kayabas and even then they switched back to Marzocchis for 2010.

I weigh a bit less than you and racetech recommended .90kgs. I set my air gap to 110mm and it is definately too little.

Totally agree! I did the same thing with new springs from Traxxion Dynamics and I weigh quite a bit more than you, and it made a world of difference. $120 for the fork springs + $110 for the shock spring + $225 in labor for the install = totally non-mushy Hyper! :D

the setup is important too. The fork felt super harsh and actually improved when I added compression and preload. This was because the fork was riding way down in the bottom of it's travel. That and the lack of air gap was basically locking the fork.

Right now my bike is set-up with about 33mm rear & 40mm front sitting on the bike.
The Hyper seems to like a "stinkbug" stance to weight the front end, I also have the adjustable rear link extended to the maximum for the most ground clearence. Aloha Alex

I was originally going to get .95 springs for my weight, untill I found out that the stock springs were really only .65

I also used the Racetech spring caculator and with the light weight of my bike I got a .88 spring number.

Ed Sorbal convinced me to take small steps, as there is a BIG difference in the springs from the .65 to the .85's. I'm glad I listened to him. Forks feel really good now. Aloha Alex

that is the big thing with a spring swap...you can no longer achieve the 50mm sag as with the stock setup. I think with no preload dialed in, I am just over 40 mm.

So did Lindemann Engineering say they would make more .85 springs?
Yeah, I could call them but I thought I'd ask Alex, thanks.
Sure he will, I gave him all the specs he needs, tell him what spring rate you want & he will have them made for you, from anything from .75 to 1.0

Talk to ED and he'll help you decide what spring rate might be right for you. Aloha Alex

If you want a 50mm sag, he can make you a shorter spring, stock is 295mm long, maybe a 290mm spring is what you need, ask Ed he'll help you with what you want. Aloha alex

Alex, still loving the new spring?
Thanks
YES! So far so good, we just finished a Ducati track day at Fontana today, I signed up for the #2 or B group because the Hyper can only do 130mph where the Superbikes can hit 160+ down the long straight.
But the Hyper owns the corners, and at one of the sessions I was able to turn the fastest lap time in our group, so the bike is doing pretty well.

I really think many of you should try & make the stock suspension work for you first, before spending the big bucks on fork kits. It can be as simple as a spring & oil change. Aloha Alex
