Want to get some final info on Race Tech springs swap on Hyper - Ducati.ms

Ok, well since some time has passed im assuming I can get more precise info on Race Tech fork springs they offer. Im sorry to bring this up once again but I saw to many posts with different info on oil levels and even saw a post where springs didnt fit.
So finally,
Do the fork springs that Race Tech sell fit without a problem?
Any modification to spacers or spacers needed?
How much air gap?
5w is the way to go?

Sorry for the questions but its that I have always worked on my own forks but only on Jap bikes and the info out there is more understood.

If I recall, there are only a few people that tried the Race Tech. I recall only positive comments. However, I think the conclusion is that some of the other offerings were a little easier to install the forks. Price is close, but most of the time you can find a local Race Tech shop to do the install which has some advantages. Race Tech is a top of the line aftermarket suspension company, I would bet dollars to doughnuts their offering is as good as any.

Out!

What other offerings besides a cartridge kit are you talking about?

Also im planning on doing this myself.

My bike had their 110 lb springs with 5W oil when I bought it. Having ridden stock Hypers I think it's a great improvement. I've never been a big fan of progressive rate springs. Turn in seems easier, and I never notice the wobble I've felt with the stock setup.

Would you happen to know what brand springs are in there?

I am assuming you are referring to .110 kg fork springs. They are very heavy springs for the hyper. I weigh 210 lbs. and racetech recommended .90 kg springs for me.

OP:
5 weight fluid helps tame down the very heavy compression damping. I actually am maxed on rebound now, but it happens to be perfect at full rebound for me.

I would start with 115 mm air gap and adjust from there.

If you find that you are not acheiving full travel you can remove fluid by removing the 14 mm compression adjuster nut and permitting fluid to escape. I would only do a bit of fluid at a time.

I use my fork oil height gauge to measure how much fluid is escaping and remove the same from each side.

Remember true bottom is above the axle casting. I believe it about 45 mm from the axle casting.

If you are bottoming, you could add more fluid by removing your fork caps and allowing the forks to collapse.

You will need a fork oil level guage like the one traxxion and motion pro sells. You also will need to remove your handlebars. But, it sure beats removing the forks from the bike each time you want to adjust.

Yep .110 kg. They say the mind is the 2nd thing to go.

And yes, I unfortunately weigh more than you. I'm 6-4 and 265.

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

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.

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

Racetech springs are modified existing dirtbike springs, they will come with their own spacers.
I used the Racetech spring calculator to help me with my spring rate, I settled on 0.85, a BIG difference from the stock 0.65s

My springs are exact copies of the stock springs just heavier, they use all the stock parts like the spacers.

Marzocchi recommends 7.5w in all their forks, the suspension experts say that you might need to go to a 10w with really heavy springs, or if your compression & rebound is near maxed out. I set mine at 120mm from the top (collapsed)

My forks are working quite well now, especially at the track, they might be slightly stiff for the street, but thats OK by me, remember that mine are only 0.85 and I am 225lb+

but my Hyper is light. Aloha Alex
