Just checking in to see if this idea is even feasible. I like the look of the 2013 Daytona swingarm, just concerned that it may not work on the Streety. All the swingarm pivot hardware seems to be the same, just don't know about the weight differences or length differences. May pickup a swingarm off ebay to try and see without messing up the handling of the bike.

Not really. More of the aesthetic upgrade for me. I like the look of the Daytona swingarm a lot more than the stock Street arm.
Another user posted that the Daytona swingarm is shorter than the Street's by a few inches so it may affect the handling of the bike but won't know until it's tested. Also weight may come into play as I don't know the weight differences between the two either.

Just a quick update:
I ordered a used 2013+ Daytona swingarm off eBay after some research that both the Street and Daytona both use all the same mounting hardware and spacers. We will see if thats actually true.
I haven't removed my swingarm off the bike as I am currently riding it as much as possible with the absurdly warm and relatively dry February weather. From the Street Triple measurements I did take, it is roughly 62.8cm (about 3cm longer than the Daytona's) from the pivot axle to the rear most side of the rear axle slot, but that was it installed with my rearsets in the way. I'll take some more exact measurements when it's off the bike. Didn't get a weight either.
I'm excited to see how the Daytona swingarm is going to look on my Street Triple R and how/if it will affect the handling characteristics with a 3cm shorter length. Suspension can't really be looked at until then either, and will have my suspension shop properly set up the rear shock for me as well.

Have your shop set up the forks to match, too. With the potential geometry change, you'll need to do that to maintain proper handling balance. :thumbsup
The swingarm is shoter so your spring and shock ratio will increase. IOW, it will ride stiffer, but that's probably not a bad thing. The stock shock is soft IMO.
As others have said, then make sure your front and rear sag are set afterwards.
It should turn easier too. If it's a little too easy, then you could always raise the triple clamps (drop the fork tubes) a little to increase rake and trail.
I found the Triumph swingarm tool handy for reinstalling the swingarm on my ST3. There are ways around it (pliers, for exa), but the tool insures it's done right and can be coupled with a torque wrench. It was $15 or $20. I can't quite remember.
I'm surprised anyone would go through the trouble of swapping a swingarm just for aesthetics but to each his own. You would probably cringe at my homemade lexan windscreen that's sealed with gaffer tape. Ha ha. It's functional and that's most important to me.
I like the longer wheelbase personally. The bike is very stable especially when spinning the rear tire on exit.
Let us know how it rides after you're done. Good luck!

Does anyone have any idea why triumph would go to the trouble and expense of developing and manufacturing swingarm specific to the triple?
If they specifically wanted a longer wheelbase (again why?) Couldn't they have just extended the Daytona one slightly?
I'm thinking they did it for the same reason they detuned the motor.
Detune and ugly it up a bit to make sure the triple didn't outshine the Daytona and also to make sure everyone would go crazy for the upcoming 765 and the "new" gull-wing swingarm
Thoughts?

Finally updating my post! Swingarm was installed with no hassles! I did need to order the Triumph swingarm tool, but eBay had one for $20 or so. The swingarm came with all bearing and spacers needed for the installation. I believe the only different part between the Daytona and Street is the long spacer that goes between the gap in the arm. Daytona swingarm is the same weight as the ST3 swingarm but it is 1.5 inches shorter. The linkage for the suspension is the same on both bikes.
I have about 3k miles on the bike with the modification and so far I love it. It goes above just the aesthetic of a better looking swingarm and bike, but the handling is better too. I've noticed no straight line instability, but the bike tips in better and tears out of corners much better and without harshness or excessive wheel spin; it really feels likes it's on rails. Shorter wheelbase has also made wheelies easier, may be a pro or con to some people.
Next up: install Daytona cams and get bike re-DynoTuned.

I realize this is an old thread but its the best I've found so fingers crossed.
I was looking at doing the same mod and since I'm in Thailand parts are expensive to ship so I need to know what I'm getting myself into.
From what I can tell it looks like you can use pretty much all the OEM fittings like the shock, shock linkage etc.
But I'm a little confused what the "long spacer that goes between the gap in the arm" is.
I was looking at this on ebay:

Looks complete minus the mud guard.
What else do I need to make happen?
