2010 owners handbook spring rate suggestions?

Looking through the owners manual for the 2010 Husabergs, it says that a 7.6 rate spring should work for those up to 200 pounds or so. I go 230 with no gear. So, on my 2010 FX 450, following that logic, I install a 8.0, set the static at 35mm, and proceed to check the race sag. 125mm 8O


What are the other resident big-boned and tall dudes running on the new bergs? This has probably been addressed before. If it has, telling me I am lazy for not searching and providing me the proper link will suffice as well. :D

Thanks

I'm not sure what units you are working in but I installed an 80N/mm spring on my FE570 (by chance, it's exactly the same spring that I removed from my 2008 model FE450) as, like you, I am slightly larger than the average bear.

The spring works well for me but it's important to remember to increase the rebound damping of the shock as the stronger spring will need firmer control as it expands.

I'm 6'0 220 and I think we went with a 7.8. I'm in spec but if I gained 10 pounds I'd be out of preload. But, I had the KTMWorld suspension "full meal deal" done including bladder and body. I've ridden a few bikes with there setup and they all were amazing.
 
hello John

I hope all is well.

I'm 240 with out gear, and run an 80 rear and 48s in teh front. It seems most people that weigh about 200 can do A 76 rear and 46 fork springs. I have a full meal deal Enduro Engineering revalve and it works very very good, much better than teh std dampening with the same springs. SHane is about your weight, and riding an FX and runs a completely different set up, considering his weight. He's been revalved by EE as well with 48 fork springs and I believe he told me a 84 or 86 spring in the rear, which I would think would be terribly unbalanced with a OC fork. The CC fork does a way better job of staying up in the travel, so I think that makes it possible to use the stiffer spring. It would also make sense why you cannot get the sag to work with the 80 spring, I think the fork acts stiffer and would transfer the weight to the rear, requiring the stiffer shock spring.

Hope this makes sense and helps you out.

cheers

Hi Lee,
Thanks for chiming in, I was hoping you would since you are close to me in size. What you say does make sense. I have a 8.4 spring on the way, I wanted an 8.6 but the supplier did not have one on hand. I'll stick with the .48s in the front for now. I did get about 30 single track miles in with the 8.0 and the bike worked pretty well even with the excessive sag. I love the CC forks so far.

On another note, the FX first gear is TALL, but it works great with the Rekluse that is installed. Fun bike to ride!
 
Where do you guys get your springs from?

I'm about 200 pounds plus gear, you think I'm ok with the stock springs?
 
i weigh 85 kgs without and 98 kgs with gear and got an 8.0 Nm rear spring and wouldnt want any less (as 7.6 is wrongly recomemnded by the manual) - if you weigh more than me, an 8+ rear spring for sure will be required.

Fizz, I'm the same weight as you and have the standard springs at the moment, i was going to go up to .46 front and 4.8 rear, but from what you say that may be to soft. What type of riding do you do? Need somthing that will find grip in a UK winter :roll:

Cleo,
Call Jeff Slavens at Slavens Racing in Colorado. He is a WP suspension guru who also rides a Husaberg. He sells springs (in yellow) and will steer you to what you need. He also has a great web site. I think you need an 8.0 on the rear but also you need to go a step or two higher than stock on the front as well. Balance front to rear is critical on the new Husabergs, especially if you have open cartridge forks like you do.

Riding is rutted single track, roots, rocks, hills - all the yucky stuff - but slow and technical - grade 2/3 rider who crashes alot.
The stock rear spring for our weight is a shocker (excuse the pun)

Fizz, I believe the manual wants you to use your weight w/gear, so 8.0 is what it calls for you. It doesn't state it in the charts, but pg.36 for checking sag it says w/gear.
 
Oh man, i'm way undersprung by 30lbs... Time to get springs.. Most noticeable when I'm going down steep, rocky decents, I feel like im gonna go over the bars..
 
I just replaced my springs and my sag is still too high, so I would appreciate some advice.

I weight about 202 lbs without gear, around 230 with gear. I am a recreational rider on a wide variety of terrain.

My 2010 FE450 is brand new, but the springs are used - so the springs are broken in, but not the rest of the suspension.

I put .48 on the front and have the preload set to 2. The static sag is about 33.3 and the race sag is 52.4. Is that too high? The fork feels really stiff just pushing it in the garage, but the sag seems too high. Should I use more preload? Or do I need to move to a .50 spring?

On the rear I have an 8.4. I first set the preload to 10mm, but the race sag was way too high. I now have the preload at about 14mm, which gives me a race sag of 104.8 - but the static sag is only 22.2. The rear spring feels much softer than the front, just bouncing in the garage. Will this spring work okay for me? Or do I need to move up to an 8.6 or something?

I was surprised that my sag measurements were so high since many others in my weight range recommend either .46 or .48 for the front and 8.0 or 8.4 on the rear. Why is mine so far off?

Do I need to replace springs before I tune my clickers? Or should I go with it until the bike is broken in?

Advice appreciated.
 
I am using a 8.4 and I am easily 20 pounds heavier than you. This spring is correct for my weight. How are you measuring your rear sag? Your butt should be in line with the foot pegs--you should be sitting on the front of the seat. At 202 pounds, you should not need a heavier spring. Used springs may be a crap shoot too. I'd set the free sag back to 35mm, put some time on the bike to break in the suspension, and go from there.
 
DeeG might need the 8.4 for all the accessories he's added, but don't feel you have to be right at 105mm either. Check out EE's website - they have a suspension tuning guide, recommending 105 - 115mm sag with 35 - 40mm of static sag on the rear. Most guys seem to favor a little more race sag than the manual says.

One thing I do to help see if they are balanced is to engage the front brake and bounce up and down. Front and back should move together pretty much. 52mm sag up front unladen sounds like a lot, but if it feels unbalanced you can add preload easily - nice thing about the OC forks.
 
Guys,
Is there any spring rate graph for the 2009 FE570?
I am reading the posts in this forum but I can see a little discrepancy with the units.

My weight is 95 Kgs (210 lbs) w/out gear and around 108 Kg (238 lbs) with gear, I am 1.84 m (6 ft) tall
My bike has the originals springs (4.4 N/mm front and and 72 N/mm rear)
Just went yesterday for my first ride with it. I feel like driving an old Ford LTD ( I mean don't feel the holes) but I noticed is too soft when I land so I need to increase the springs.

If any of you is very similar to my dimensions then post the setting that I should use.

If I extrapolate the recommendations from the manual then I should go for:
Front: 4.8 N/mm (0.49 Kg/mm)
Rear: 81 N/mm (8.3 Kg/mm)

Any comments?

I weigh 92 kilos/ 14 stones. FE570 2009.

was on 48s front, then went to 50s plus I have revalved them 5-7 times to get them how I like them. on the rear I had an 84 and that was nice but I've fitted a 90 and went out on it today. only green laning but it felt very plush and boy could I hit stuff. it may be the other aspects that make me out it for an 86 or an 88? the rear shock has now got even stiffer damping than the FX. I don't have any dip on the rear when accelerating now and it whizzes up a bit although with all this slime and mud I'm not sure what would have coped. maybe I need an enduro TRACK again.

to that end I'm trying Jeremy's 'platform needle'. Drehwurm has put me onto it as suiting someone like me. I like a strong spring with little preload. so what with the MX-T plattform needle and the X bushing I'll be sorting it I hope. that or learning!

regards
