Quick Throttle Mod

[DEcosse]

From this TriumphRat.net reference thread andrewt showed that it is possible to swap the Triumph throttle grip with a Yamaha R1 grip.

However from the same thread, Martin_R made this important observation:

The caveat is that the actual throttle grip cam on 1050 is 36.5mm and on the R1 grip it is 37mm. So translated to actual throttle degrees the change is only a few degrees. Not worth the trouble, if it is a quick action throttle one is after.

But then I found the following thread on a Gixxer forum that shows the differences of several throttle grips, knowing that the R6 Grip is a VERY popular swap over many different marques:

(please note that you will be unable to see the images unless you are registered member, however all the text is visible without registering)

So the next logical extension for the Triumph is to fit the R6 throttle grip, which has a larger cam (40.5mm) and that will decrease the rotation proportionately.

From that thread and andrewt's I have amalgamated the pictures to show the differences:



Since the R1 and Triumph grips are readily interchangeable per andrewt nad the R1/R6 grips themselves are interchangeable with each other, reasonable to assume the R6 will interchange with the Triumph (caveat - I have not validated this empirically!)

An R6 throttle grip part number 2C0-26240-00-00 from somewhere like http://www.mrcycles.com is $18.58. (list price $25)

If someone validates the fit of the R6 throttle Grip (and any mods necessary), we'll sticky this.

Very interested to hear if someone has got the large R6 combo to work and how.

One more issue with at least the R1 tube, and looking at that pic suspecting on the R6 too, is that the Yamaha cam is thinner than 1050. This results in quite an annoying sideways slop. Easy to shim out of course, but something to consider still.

Also read the GSXR thread fully to confirm right part number for white & larger R6 part number. I ordered a R6 tube based on that same Gixxer board thread a year ago and got a 36.5/37mm black tube identical to the R1. Confusion in the info on that thread or at the Yamaha dealer network as it seems many other had similar results.

I think I have the correct part number in my opening post Martin?
I do see that there was a lot of confusion on the Gixxer guys' part however.
Yes, throttle shims may be required to take out any sideways 'slop'.

Unfortunately I do not have the part number I used anymore, so can't really say if they have now updated the info or not.
I just remember that the part number was different to R1, but the actual part in the bag was the same.


Edit. One more option for quick action might be the G2 throttle tube + the 025 & 050 cams:

Edit2. Just got a reply from G2. The cams that suit their 1050 Triple tube are: 100Y (stock size), 050Y (10% larger) and 025Y (20% larger). If you want only the quick turn cams and not their "throttle tamer" cam, you can order the combo you want via email/phone. The webshop only has the tube+tamer bundle.

I do a little land speed racing with my S3 and i think this would be a good mod for that sort of competion. I have to roll my elbow far up before i leave the line because i'm trying to keep them tucked in and out of the wind and my wrist strait at WOT. If i can get it done before i leave for the Texas Mile in March, i'll let you know how it worked.

[Martin_R]

I gave the 40.25mm (Y050) G2Ergo cam a try. This is the change in turn vs. stock tube. Larger cam drops turn to somewhere around 65 degrees:


But in order to make it work you will have to remove all areas marked in red:




I must say that I am not completely happy with the throttle because:
-the aluminium tube against cast housing is not as smooth as plastic (the R6 tube would be better)
-the removal of two small guides from housing mean that cable in theory can move to side of housing and possibly bind
-you will have to remove 2 support pegs from cable and also the only solid part of the outer guide tube -> the cables have room to move around

All in all, I think a proper quick action throttle would be a more solid option. I will go this route or back to stock as I have trust issues with the modded setup.

Just ordered an R6 throttle tube.

We shall see

Just throwing this in there I bought Rizoma grips for my FZ1-N and it came with three different wheels/Cams for the cable so you could pick the speed you wanted....
