08 525 S - Changing out the suspension system

2729 Views 16 Replies 5 Participants Last post by  Schmoople
Right now the whole suspension system is stock. I'm in intermediate rider and I ride on a lot of fast speed power lines and rail road beds. I was looking at this earlier today and was wondering if this:

Lone Star Racing DC-4 A-Arms and Fox Float X Evol Suspension Package

Plus some wheel spacers in the rear would help widen it up a bit. I'm thinking the floats should ride quite nice. Now, I'm just wondering how to lower the front and rear. Any ideas?

For a trail rider like myself (I ride sandy trails and whooped out power lines (FL)) where running a bit wide isn't going to hurt me as much, am I really going to like going with the wide a-arms or would I be better off with my stock a-arms and getting some float 3's and tossing on some wheel spacers?

Pretty much, I'd like to get the bike to ride better, and have a great range of adjustment, which I think the floats will give me. When it comes to the a-arms and such, I don't even know where to start, or if I should stay with my stock ones. So, any advise with that would be a huge help, and any feedback/reviews on the floats for trail riding would be awesome as well. Also, how are you guys liking running Maxxis Razr II's up front and Razr I's in the rear in the sand? They work well?

Look at this. Easy, plentiful, cheap, and will suit your needs. Get GBC tires; Affordable and GREAT TIRES. You're new so click on the ORANGE. http://www.ktmatvhq.com/forum/outla...ocks-outlaw-525s-love-way-sits-rides-now.html

I'd imagine if probably need them revalved for my height and weight. I'm 250lbs. Right?

I saw the thread. I was excited to read it...but there wasn't really any info available in the thread.

Any particular year yfz shock I should look for? Will 2014's work? Is there a price range that members have been paying that has been typical?

The YFZ450 shocks are around 15 1/2. The YFZ450r are 18+. This is eye to eye.
Any year YFZ450 and YFZ450X will work with stock a-arms.
I would say only use the YFZ450R if you're going +2 a-arms.

YFZ450 = 46"
YFZ450X = 46"
YFZ450R = 48 1/2 +

I'm wondering if I should go with the wider a-arms and the 450r shocks or keep my stock a-arms, use the 450 shocks, and go with a wheel spacer.

Any feedback on what people have been having better results with as far as trail riding?

For trail riding my opinion would be keep the stock arms and use yfz450 shocks. Stay away from the wheel spacers. The stock width of your S is wide enough.
Save the money. The shocks will be a great improvement for your needs. If you widen the arms you will have to get an axle. This is expensive. You could use the money for a head/intake. This is an area on the Polaris that needs attetion.
NOW YOUR GOING FAST TOO.

In your opinion, with me being a 250lb guy, will I need to have the Yfz shocks revalved? Should I send out the yfz shocks and my stock outlaw rear shock for a revalved so they can be matched up?

So, you think even adding a 1" spacer on each side would be a waste? I read good reviews on them, but I'm unsure of the quality of the review.

Right now I have a Yoshimura rs-5 full exhaust, jetted, and Rath racing intake with k&n and modified airbox. No internal engine mods yet though. I picked up the bike hardly used. I'd be surprised if it has 25hrs on it.

Stock YFZ450 shocks can handle 250 lbs. easily for trail riding. If you were mx racing I would send out to be reworked.
I do think the spacers would be a waste.
I would immediately change your k&n filter to a FOAM filter for your riding; insurance for your head. It protects against dust better than what you have.
The mods you have are good. Get the shocks and you're set.

That's awesome news on the shocks!

Glad to hear I don't need to waste money on the spacers.

I'll pick up a foam filter on my lunch break tomorrow. I knew I should have trusted myself on that one and not let myself get talked into the k&n.

Any recommendations on getting the ride height down on this bike a bit? Doesn't have to be anything extreme, but an improvement would be cool.

Stock height should do well although they are adjustable.
K&N is best in the dunes. Almost all trail riders prefer Foam due to dust.
Make sure your foam filter will fit your intake. FCI carries them. Just received one for YFZ450R Saturday.
Check ebay....I through FCI, check their website out too.

There is a Polaris forum that will really help you out too. I'll try to post the link. www.polarisproriders.com
you can drill the front arms to lower the ride height also at zero expense to you. remember lowering the front and not the rear will change the handling and create issues. simply swapping to shorter length shocks isnt a be all end all solution. get on polarisproriders.com and do some reading. far better outlaw info on there. some of us have owned them on here but most everyone over there owns one. also there's typically a boat load of cheap parts!

What you referring to in regards to FCI? I'm not following.
FCI stands for "Fuel Custom Intake. You said you have a Rath intake. Check with Rath for a foam filter. I said FCI because theirs is oversized.
What bend are you guys running on your flexx bars and which mount are you running on the stock stem?

I think that should wrap it all up for me once that is answered...then it's time to spend money!
