Thanks, that helps a lot actually.

I live very close to Sears Point (Infineon) and there's a world class go-kart track above the big track that they run Supermoto on every week, I think it's like $60.

I may try a track day on the small track before running on the big track, even though all my past experience is on the big track. I think it will be fun.

I'm sure I'll run into someone there who can give me some tips.
Ive done a trackday at infineon years ago on a ktm motard. Too many places for the big bikes to stretch their legs, where im stuck at 95-105 mph depending on gearing... Id recommend buttonwillow for hyper owners over all the tracks in north/central california. The cart track u mentioned sounds interesting!

So they will customize spring/oil weight for rider weight and intended use or have they just made a batch of upgraded springs for these bikes? thx :)
This is primarily a 1100 thread as the forks are a well known issue, but there are 796 owners who have done front work. Springs come in all shapes and sizes and you just pick one for the correct bike/rider/style. On the other hand here is a very nice chart of the oil weights and an overall good site for learning Peter Verdone Designs - Low Speed Damping.

Seems like traxxion dynamics can get you springs which leads me to believe that race tech or lindeman engineering should be able to as well. http://www.ducati.ms/forums/92-hypermotard/142095-new-suspension-my-796-a.html

after doing this fix, I feel like my hyper 1100s is both more compliant, but more stable and dives less under heavy braking. haven't tried any fast turns yet, but it was a huge positive change from the stock progressive springs.

I have some springs I got from another member here that soon I hope to install. They were too stiff for him, but sound perfect for me (.9 rate with my weight being 220-230).

I'm looking forward to trying my 1100sp out with the new springs and oil and air-gap.

Here's a few data points for the rider weight/spring rate graph:

2008 HM1100S
rider- 200lbs w/all gear
current setup:
forks
spring: traxxion .75, stock spacers, 50mm sag
oil: repsol 5w at 110mm (approximates golden spectro 7.5w)
RB 1.5 turns/comp 1 turn
ride height- -5mm

rear
spring: ohlins 1092/34 - 100 (571lbs/in) about 30mm sag
RB 15 /comp 10
ride height- 4 threads each end

NB: per Dan kyle, don't grab a shorter spare spring you had lying around even if its a better rate- with preload, the stock 170mm 1092 spring is close to coil bind at full travel.

The bike likes the changes and it really responds to a stiffer rear end. Feedback is improved, as is comfort on bad roads. The bike doesn't sack out as much and consequently the geometry stays where you set it.

Hey all,

I'm looking to do this mod. I have the '08 base model 1100. I have a couple questions:

Are any special tools required for this job?

Is it 100% certain that all 2008 1100 non-S came with Marzocchi forks?

Thanks in advance!

Ended up buying the .85 from Ed at Lindemann Engineering. He suggested using 15w at 135mm air gap. I weigh anywhere between 210-220 depending on the time of year (seriously). I'll write here again if I'm unhappy with it or tweak something if these specs don't work out for me.

I'm planning to do this mod and looking to order springs first of next week. When I run the calculators and look at previous posts 0.80 seems to be the weapon of choice (2008 1100S, 175lb rider). I fall more on the adventure/tour end of the spectrum than the track end. I ride a fair amount of bumpy country roads and some gravel forest roads too. For that reason I was going to go a little under the recommendation, at 0.75. Is that logic sound??

Yo, back from the dead. Haven't done much with my Hyper since I was away last year traveling (did a tour of Vietnam on a bike, also really cool). Either way. The forks on my Hyper started leaking, severely. I asked the company that did it what specs they used and they told me they used a Wilbers 7.5W oil with 90mm air gap. Now I always did find the front a bit on the rough side and with the forks leaking it become softer and actually felt a bit better to me. The bike would dive a bit more during braking and use more travel compared to previously (before it would maybe use 2/3 travel, after the leak 3/4) so I've let my mechanic know to use a 100~105mm air gap, whichever he prefers, to see whether that will soften the ride up a bit.

Will let you guys know how it went.

How many miles did you get out of your front forks before the decided to leak on you?

Finally

I finally put stiffer springs in my 08s, traxon Dynamics, $175 with 15wt oil. Only had time for a 10 minute ride but feels transformed. 150lb rider, .82wt springs, should have done it years ago. Feels like I need to tweak the rear now, before the front was the biggest issue. This thread was a great help. Thanks.
