Is this the right R1 Throttle Tube for my 450?

[pete]

I've seen a few guys report using an R1 or R6 throttle tube to get a quicker action throttle than the standard tube. I'm finding it annoying having to wind the throttle so far to get to WOT now that I have my carbs a lot better...

Is this the right one to replace my stock one while keeping the stock controls? I'll be sticking my foam grip back on over the top.

it will fit fine Pete, as long as you fit the R1 motor in your GS to match it.

not sure about your bike Pete, but this is what I got for mine, from the local Yamaha dealer....

the throttle tube change from your stock one, to using one from a 2004 Yamaha R1

(Throttle tube for a 2004 R1 (4YR-26240-02-00) )

Ahhhh it seems it will fit, I just checked the list of fitaments it's showing....

I have never felt the need to do this mod, but simple logic tells me that you should expect one other change when you do this.

Be prepared for a heavier feel at the throttle grip.

My line of thought (and I could be wrong (again)) is that it takes a certain amount of force to open the trottle all the way. Whether you measure that force in pounds, kilograms or Newtons does not matter. By turning the throttle grip, say, 3/4 turn, you will spread that effort out over 270 degrees of rotation. If you install a quick-turn throttle and it only has 180 degrees of rotation, my thought is that you will have 50% more effort to turn the throttle or to hold it in any given position.

Someone who has actually done this mod will have to confirm or deny, but that is what I am thinking.

Then again, those who have done it might find it an acceptable compromise, have gotten used to it and don't really notice it much any more. If you are doing most of your riding in town or out on the twisties, where you are constantly changing throttle settings, you might not notice it as much, but I also tend to do some longer rides with longer stretches of holding a steady speed. That is one reason I have either a throttle lock or a cruise control on my bikes, but let's face it, not everybody rides like I do.

I am using this mod, and find it OK, then again I cannot compare to how the bike was before the mod as it was so long from the last time I rode it, I really don't remember how it was back then.

But I can say I do like the fact the a short twist of the wrist and I can be at WOT, if the nee arises.....maintaining a constant speed is not an issue either as it's a short twist of the wrist to the spot I need and can hold it there with no feeling of it wanting to come back to closed position.

Cheers

I just did this mod on my Super 8.

Yes there is an increase in throttle force, but I find that it is negligible and that riding is much more comfortable as it takes ever so much less to make throttle adjustments and so there is less wrist contortion required. It is best in the twisties. Of course I did the $1 mod.

[spyug]

What he said. A bit more effort but not anything annoying or even really noticeable. I've done it on 4 of my last 6 rides and it works flawlessly. Certainly does away with the kinking of the wrist. well worth doing IMHO.

Cheers guys, I shall procure one at some point soon and do the swap over.

GK and Spyug, thanks for the confirmation!

Steve, I expect you're right, but I find it hard on my wrist trying to find the right compromise holding my wrist in the right spot for comfort for low throttle openings or closer to WOT. My wrist is a little dodgy at times so the shorter action should help there too.

Jim, I was going to do that originally but I was worried about it moving without glue which would make it permanent... I also have a fair sized crack in my stock throttle tube so this is an excuse for a new one of those too

Adrian, I reckon an R1 motor might fit in the 450

[pete]

Purchased... now the waiting begins...

If sized properly the PVC is captured on all side and can't move around.

[pete]

Yes true, I can sort of envisage that in my head... oh well new one hopefully on the way before too long

[GateKeeper]

I grabbed the new grips at the same time, if your grips are ratty get them as well if it's not too late..

Nah I like my foam grips, they're still in good nick and will be being reused.
