Are the forks the same? Also is there a market for used stock forks? Thanks! My fork seal is leaking. Thought about doing an upgrade and getting repairing it at same time but just saw that Erik Buell Racing has 1125 forks with the Showa internals for only 950.

Not even close.

Also note, your SS has the STT forks technically, so you will have a high ass if you went with the 1125R forks (which I found out first hand will fit the stock trees with a little persuasion) : )

Oh if you do get the 1125 forks, get a new rear shock from Erik Buell Racing too, I don't know what they offer for the long frame bikes.

Sounds like forks aren't even an option anyways. Just looking to upgrade suspension a bit. Might even just do oil and springs in stock forks and a spring I'm back. Should help some but I'm worried the shocks damping could already be poor anyways and replacement would be better.

Does bigger forks mean they're better? More oil? Better damping and such?

I have the Scg, will the 1125 forks fit? Cut them? Different triple tree?

I ask because I'm 140lbs and the bike bounces me around a bit...

I'm ready to change the forks oil so should I get different "lighter" oil?

At 140 pounds you are probably perfect for most stock fork spring rates. The scg is a short travel setup though. So it will be harder. I'd have a suspension specialist give you a basic setup if you haven't before.

I did, 2 experts, 1 set the front pre load 6 turns and the other back all the way out.

Since I have yet grasped the cause and effect of setting suspension that caused more confusions than you know.

If same length but bigger forks compensate for smaller shorter forks... so I was thinking.

Not sure about that logic. The suspension has two adjustments. Longer forks will raise the front and give you a strange geometry. Maybe switch for regular S forks and shock parts? That will give you more travel

Maybe you can explain exactly what the forks do that bug you.

I was guessing that if it can't go longer maybe it can be wider, more oil?

Anyway, the first adjustment made the bike more stable, not as twitchy as original setup. It was made by the expert with experience setting up bikes for 120lbs girls, riding 600cc bike, and he said what normally by the book won't work. But it still bounced me off the seat.

So I said as such at the second adjustment, and then the front pushed and slid on even slow turns, and worn on the sides faster than the center. And now I need new front tire.

Also there a metal like knocks than I feel not heard over high speed bumps, the forks' high speed compression. I was told it's just low quality stuffs, and just get them rework with better internal and such....

Have you tried setting it to where the owners manual or service manual says you should set it?

Other than the old oil in my forks I was much happier with the suspension after setting it to the Buell suggestions based on the type of riding I am doing. Nothing on the track which is where I expect the stock stuff to start showing a lack of performance.

I think the idea behind the bigger fork tubes is just to make them stiffer. I don't think the oil volume would make any difference unless you are working the fork enough to overheat the oil. I think that's hard to do unless you're doing off road endurance racing.

The forks have three settings, don't they? You have looked at the manual?

I found the base settings to be a little off but the directions were easy to follow. At the end of it all, I have a comfortable ride.

Check around, I found a local Ducati tech who was fully experienced with these forks and did a great job for a very good price.

So the tubes are bigger for strength but the inside diameter same, I see. Just a thought as I'm still learning this stuff.

Third adjustment, also a suspension only shop, same affair as the others as in he measured sag with me on the bike and fully unload and such. He took a quick test ride around the block and said it was normal now.

I hit the twisty and damn nearly crash! The bike wiggled big time and with the "drop in" feeling when leaning over, and bottoming out the forks much more often, on bumps that it didn't do so before.

Then he told me he never work on a Buell before and offered to ask around but I said not to bother. I demanded the $20 back.

Now I set it back to "Less than 150lbs" setting in the hand book.

A side note: I've never heard the Jardine from afar before, well not in real life anyway, and it's really loud! But the tone is warmer, not like what it sounds when I'm on the bike.

Also sounds like you may be riding a little harder than the standard settings, you should probably set it for the sport or track settings when you are pushing it that hard. There is no single setting that will give you nice soft ride for the highway commute and firm support for pushing it really hard.
