I did the switch and it took all of maybe 5 minutes to complete. The first (and only time so far as it is damn cold) time I got out on the bike, I noticed a big different with how little you have to twist the wrist to have the bike start moving. I'll need a few rides to get use to it, but I think it was a good switch.
I did this mod so long ago that I forgot what stock felt like. My buddy got a 2013 STR and we traded bikes for a quick run. Man...that 1050 tube makes a HUGE difference.
I got the throttle tamer a couple of days ago....but its to freaking cold to go put it on the bike. I did get the grip changed over though...should have taken a pic of it first, but latter on I will take one that shows the difference in the cam profile and post it here. Just wish I could report on how well it WORKS, but according to the weather man, that will be at least a couple more weeks.
This mod is well worth doing. It makes the throttle so responsive. When I sold my D675 I took the 1050 tube off so I could fit it to my new Street Triple.
Riding the D675 with the stock tube on again felt horrible having been used to the 1050 tube.
Needless to say as soon as I got the Streety home the 1050 tube was fitted about 30 seconds after switching off the engine!! Lol
I bought a 1050 throttle tube for my ST but never installed it. I've got some new clip-ons and grips coming for the 675R, so I'm going to give it a go.
FYI: Rizoma grips come with three cams; the middle-sized cam is the largest that fits in our housing and I imagine is similar effect to the Speed 3 cam. The smallest cam (the one your "supposed" to use) is just a hair larger than the stock cam. I like the large cam so much better.
Ugh. I started doing this but there wasn't enough free play in the throttle cable to get it to work smoothly! Triumph had the adjuster nut all the way in already.
I started going down the route of adjusting the throttle cable itself, but that required a good bit more work than I was willing to do this evening (removal of the ECU, fuel rail, air box, just to get to the adjuster).

Totally - though the '13 Daytona and Street Triple have the same instructions in the Triumph service manual. So should be applicable either way. I think the main thing is that I was tired and hungry and it was dark out. I'll try again when I have time.
Especially Tronix and Ken C for their illustrated step by step photos.
I was a bit wary about this mod, as the stock throttle was a bit jumpy.
I installed the 1050 tube yesterday, and just came back from a test ride. The part number is:T2040331. Interestingly it is made in Italy.
It was a snap to install, once I got past the fact the one of the screws on my
bike had been buggered, and I was very careful in removing it.
The reports of doing it in five or ten minutes are all true.
As far as riding goes, I feel it is a big improvement in two ways:
1. The bike just feels faster, and the sense of throttle control in acceleration and deacceleration seems better to me.
2. Shifting is smoother, both up shifting and down shifting, due to more positive throttle control.
As everyone has said - " the best ten dollar modification one can make".
While I was at it, I replaced both of the screws that hold the throttle on the handlebar with stainless allen head 5x20mm screws.
That being said, I am not sure that I will recommend it to a friend of mine who is a novice, and just got his Streety, until he has gotten a few more miles under his belt: he doesn't need to go any faster.

Nice. I've been riding the Triple with the 1050 throttle and it feels natural. I'm taking the bike to Barber in a week, so I'll see how it compares on the track.
This has probably been covered before but the Street 675 throttle measured out at 32.04mm diameter and the Speed 1050 throttle measured out at 36.46mm diameter. My measurement of the throttle turn (1" turn out of 4" circumference) put the stock throttle at 90 degrees to WOT. Based on both turn measurements and comparison of the diameters, I think this puts the Speed 1050 throttle at 70 degrees to WOT. Or thereabouts. On my last couple bikes, I've installed the Yam R6 throttle which, I think, is 60 degrees. 60 would be nice but 70 will have to do for now...
I measured the Yamaha R6 throttle the other day. 40.57mm diameter. That would seem to support the 60 degree (i.e. 1/6th of a turn) number. I'm thinking it won't fit in the Triumph throttle housing but may try it if I get bored.
Is the 1050 throttle tube or the Rizoma Sportline grip the only options (besides something like Motion Pro's revolver) for quick turn throttle tubes? Has anyone tried a R6 throttle tube on the Street Triple?
I had to dremel the inside of the throttle housing of my gixxer to get the R6 cam to fit, but what a difference! Whenever I purchase a street triple, I hope I can mod it with the R6 throttle tube.
They work ok. Not as hot as I would like them to be but they do feel good in the cooler weather. They are the demon heated grips. Paid I think 47 bux. If I did it again I might get some hotter grips if they make them.
Thanks for the input. I figured they would not be as thick as the Oxford grips, and would stop my left hand grip from slowly sliding towards the center of the bike like it always does. I don't ride it much below 50 degrees, so this may be a good option for me.
just to make sure u get the right tube the part number is T2040331 i just ordered from my dealer and installed and i think it was under 12 bucks took me 5 minutes to get it on and its definitely and improvement
Has anyone needed to adjust their throttle cables under the air box? After my clip on and 1050 installation I'm not getting a quick snap back for throttle closure. I'm digging around for the throttle cable adjustment and find it's under the air box which is rivited in place for some god forsaken reason.
Very few have found not enough adjustment range at the top adjuster (or didn't know about the top adjuster) and had to go under the airbox (which is not riveted in place) although I would suspect that not having a snappy throttle return has to do with your cable routing when you installed the clip ons.
The routing is almost the same except for the height of the cables.
What are the fasteners that hold the air box on? They look like they need to be drilled out and replaced with new pieces similar to rivets. The shop manual calls them "fixings"
The fasteners that hold the airbox on are the bolts for the intake funnels. You'll want to disconnect the electrical plug and vacuum line from the MAP sensor on the back of the airbox too. Just don't forget to reconnect it.
