Smile ideas to upgrade performance of 04 st3

I am new to the site and happy to find a group of fellow enthusiasts.
I have an Ducati 04 st3 (dry clutch) that I had the remus carbon fibre pipes put on and a corbin seat. Any recommendations on things to add this season to increase my riding enjoyment and its performance with out sacrificing reliability?
Oh and I also got an older Carl Fogarty leather jacket off of ebay (I think that added about 5 HP to my engine)

What sort of performance/riding enjoyment improvements are you looking for? While I too own an '04 ST3, although I chose Staintune cans, I don't know that more power will really improve my enjoyment experience. I still may at some point have some port work done, maybe even some new headers and larger valves if the mood suits me.

The real performance-enjoyment upgrade on the ST3 is achieved by suspension work. Have you swapped out stiffer fork springs? The OEM springs are waaaaay soft for even the most diminutive rider. While you're in there, upgrade the fork valving. Next, lose the Sachs-Boge rear coil replacing with a Penske 3-way, preferrably with a Ti spring of appropriate rate. Use that Penske length adjustment to raise the rear end for quicker, lighter and more responsive steering. Lighter forged alloy wheels are a very nice upgrade in feel and performance, not to mention looks as well. A lightweight Metmachix alloy swingarm will also dramatically reduce unsprung mass, increase torsional stiffness in rear and make chain tension adjustments a piece o' cake. Of course the Pilot Road tires MUST go, replaced with Diablo's in my case, although some like Pilot Power's and I may give Conti Road Attacks' a go for my next set.

Creature comforts like heated grips and a GPS mount can also help but for my $$, suspension upgrades deliver the greatest improvement in riding enjoyment on any bike, including the already very nice handling ST3. Take care.

Thanks for the information bigmac. I was thinking suspension or wheels/tires. I come from a cycling background and know what nice wheels and suspension can do. I don't know what brands to get so thanks for that too. Do you do the work yourself, purchase it and have a dealer do it or have them purchase it and install it.
Best Wishes,

I do not as a practice ever let dealers or other service mechanics touch my bike if at all possible. In case of my ST3, my hands and those of a very good friend who owns several Ducati's are the only ones who have ever turned a wrench on this bike.

I've got Marchesini forged magnesium wheels on my ST2, but am getting BST wheels for my SS (I thought about them for the ST2, but they are officially rated at 400kg GVW, which can be exceeded by an ST with 2-up and luggage, so I went with the mags).

I put an Ohlins on my ST2, but the Penske is better for the ST3 as the ST3 doesn't have adjustable ride height, so the higher cost of the Penske is offset by the need for an adjustable strut with the Ohlins when used on the ST3.

These are things that are easily done by yourself. I also did the forks myself (RaceTech valves, Ohlins springs), but as the ST3 doesn't have adjustable forks, it's probably best to take them to a specialist.

The only problem I have with a ST-3 is that the engines are new and there isn't a much after market upgrades available. Thats really not a problem. My ST-3 is a great bike.

You guys are right on top of this stuff; thanks so much. Where do I find most of these aftermarket items at fair prices?

Motowheels has pretty good deals...

And as has been said. The biggest upgrade I´ve done to my bike in terms of performance was upgrade to lighter Magnesium rims. The change in the bike is fantastic! One thing for an ST rider to think about is that mag-rims aren´t really made for riding with a passenger.. This shouldn´t be a problem if your SO is of a smaller size.

A change of gearing is a wise thing.. All Ducati´s are to tall anyway.

Here is a little info on tuning the ST3 engine. Not alot, since the engine IS pretty new. Brad explains that the DP ECU really isn´t a good thing..

2010 Multistrada 1200s - engine mapped by tomtom, Öhlins mechatronics SCU and alot of mods to make up for poor skills

Thank you all for your input I will let you know what I do in the spring.
Thanks for the link to Motowheels.
The Penske 3 way is tough to find though? Any ideas on where to get that?

Check out Hopefully they have a dealer finder link. If not, contact them by phone or email inquiring about location for a local dealer.

Alternatively, almost any sportbike suspension shop of decent regard should be able to order Penske shocks (including most if not all shops previously mentioned in this thread), just be sure they know the specific application, intended maximum and minimum payload capacity(this includes rider, luggage and possibly pillion rider) and intended riding usage. This information is critical in obtaining proper spring rate and valving for your Penske unit. All Penske shocks are sold as custom valved and sprung, not knowing the intended application and usage defeats purpose of this technology. Take care.
