Let's talk fark spring rates '14 800 GSA.

Starting to do my research into available fork springs for my '14 800 GSA as I desperately need heavier springs.

I am having trouble finding accurate information on spring rates for both stock and aftermarket springs. There is a lot of talk about what spring did or did not work for an individual and a bunch of springs to fix what ever ails your front suspension but no real facts.

Does anybody know the stock spring rate for the 800 GSA?
Is the spring a straight or progressively wound spring?


What are the weights of the aftermarket springs?

I want real springs under this bike I plan to ride aggressively off road, wheelies, jumping, rocks, whoops all of it and some of it loaded with around 50-60 lb.
The Race Tech calculator says to run .95 kg springs for my 215/no gear rider weight!

Anybody already got the information sorted they can share?

And PLEASE don't suggest to add damping, the damping is doing a surprisingly good job of handling the soft stock spring, the correct spring is the first step than some good old fashioned oil tuning to follow.


Ride on,
Dusty

I love it when someone else does my homework and I get an "A" in off-road riding class. Do a good job Dusty, I need all the help you can give me.

By the way... 230 with adventure gear and camelback. 220 just gear only. 257 loaded with camping gear. Just in case you needed the specs.

I'm not the only one who needs help?

I guess it's time to find out for myself.
After the holiday I will get serious about it and my first call is to Race Tech, they do no list a spring for my '14 so I need to see if they have something or if I need to pull them out and measure them.
Some say KTM springs fit as my bike has a WP fork and shock, need to check this out if that's the case there will be many springs to choose from.

Sounds like you need a spring the same range as me perhaps one heavier.

Are you an experienced off road guy? Are you an aggressive rider?
Ex racer?

Ex-crasher on race courses, pho-neshional adventurer, and hill climb attempter. You might have read one of my last books, "Swimming with motorcycles", or "How to become a Motorcycle Crash Test Dummy". Sorry no pics of the 800 yet, but i intend to make some memories on her too.... as soon as I can get some better suspension.

Currently running .75kg/mm RaceTech and are happy with them. Had the .95 the RaceTech calculator recommended and they were too stiff for me (250lbs plus gear).

And, itsatdm is out. You are so mean Loutre.

Considering Cory's (Camel ADV) riding, i wouldn't want to install springs with a higher rate than Cory uses on my first try.

Hard telling what the story is with him.

Anyway, if you new guys are wondering, itsatdm and others did a fair amount of testing that you can see in suspension threads in the sticky list. I think most of it was in the bitubo(sp) thread. It was getting the most attention late 2010 when the US models were finally gaining traction in the market.

The stock springs in my '09 were measured at .45, if I remember correctly, when they came out. AFAIK that was close to spec. at the time. Cannot comment on the WP forks and/or the GSA.
Their calculator recommended the .95's for me as well. At the time they Racetech only made the .75 and .95 rates. I went with .75 (straight rate) and ran the local shops recommended preload and air gap (which is pretty close to what racetech recommends).
I'm your weight and ride quite hard off road, although I don't jump much. This setup has been pretty much bang on for sag and bottoming, albeit a little harsh on small stuff. I'm using 10w oil and am going try a lighter weight.

On a side note, I switched the rear spring at the same time. Stock was way too soft, especially with a load. IIRC, stock was 900lb/in. Racetech recommended 1100 and I tried that. While I was quite happy with the rate, it turned out to be an off the shelf Eibach spring with a hefty mark up. It wasn't re-boxed, or even a proper fit.
Since then I have replaced the rear shock with an Elka unit. Night and day.
I gave them my weight and riding style and they sent me a 900lb/in spring. After a year on it, I plan switching the spring for stiffer one.

By popular demand I am back. The WP forks are different than the Marzocchi's besides 43mm vs 45mm . The springs from the earlier models won't fit and I doubt the recommended weight would apply, because it appears the WP actually have some valves that provide some Compression in the forks. The early forks, only have 4 one way spring loaded poppet valves for oil flow. I have never detected any resistance working the fork when the springs were out, only rebound. That probably explains the ultra heavy spring rates Race Tech recommends.

Since Konflict Motorsports http://www.konflictmotorsports.com/a...sion-services/ offers a revalve kit for the 2013+ bikes, in addition to the Cartridge tube they offer, I think they would be the best source to recommend a proper spring. Though I am not sure they sell springs alone.


Loutre, my nuking the posts had nothing to do with you.
