Hi all, some time ago I tried dropping the front sprocket size by 1 tooth, thinking that this would make the bike feel a bit more lively through the rev range, not that it really needs it, but why not?

This didn't achieve the result I'd hoped for, instead it made the bike feel way too peaky and required a lot more gear changes.

Anyway today I fitted a speed triple throttle tube, cost $25.00 aus, and took about 5 minutes to fit. This is what I was trying for in the first place. The bike feels like it makes it's power a lot more effortlessly due to the reduced throttle travel.

With all the slack adjusted out of the cable the throttle is not jerky and for some reason (who knows why) the bike feels happier traveling at almost legal speeds.

Highly recommend this mod, however if you fit the speed triple throttle tube, be sure to treat the throttle with more respect than usual for a while.

Make the throttle more sensitive? YIKES! :eek: That's the LAST thing I'd want! The Streety is well known for having an overly sensitive throttle (documented in both professional and non professional reviews of this bike). Smooth pavement not too much trouble but as soon as I hit some bumps, slight of hand makes the bike jerky as heck. However, this is also my first fuel injected bike. To each their own, though.

I agree with Ken M1. If you need quicker response I would start to think there must be something wrong with your bike. Not many bikes out of the crate are quicker than the ST3, regardless of cc's.

No there's nothing wrong with the bike, its just faster.:D

Plus its green (an old debate) and these things have to be played with. (can't help myself)

Ken have you tried adjusting all of the free play out of your throttle cable?

The specs say to leave a little slack but this is what causes the jerkiness over bumps ect.

(I know this has been discussed before, but its getting a bit quite around here lately.)

When I first took the slack out of mine it felt like a different bike right away,hasn't jerked on bumps or chain slapped out of corners since and it has no effect on engine revs at full lock.

Plus its easy to adjust it back to the factory settings if you don't think it makes a positive difference.

The speed tube doesn't make the throttle more sensitive, it just makes the power feel on tap quicker, its quite a long wind back with the standard throttle tube.

Its my favorite mod so far and only 25 bucks :motorbike2:

More power quicker is not the issue with mine. I have to ease the throttle on very carefully in first and second until I'm going at least 30 other wise I'd be staring at the sky. Not that this is a bad thing I enjoy staring at the sky just not in traffic when there are cops around.

I don't remember exactly, but I think a 2006 or so R1 throttle tube is the cheap fix for quick turning throttles for lots of different bikes. If it doesn't work, you are only out about $10. I completely understand the urge to shorten the throttle's throw so you can get to WFO just a little sooner and with less wrist flex.

The author of the thread stated that a Speed Triple throttle does just that.

Great mod!

I just put the 1050 throttle tube on my ST-R and took it for a spin. What a great mod. If you want a handful of throttle, you have it now. Driving city streets is no problem and I don't have anymore issues maintaining freeway speeds due to wrist position.

It takes less than ten minutes and its easy to undo if you want. At the moment, I can't see why anyone would want to, though.

$10, including shipping.

I have to agree with the guy who said he takes it super easy in 1st and 2nd until at least 30mph or he sees sky (MacBandit). That was my experience...I can't imagine wanting to quicken throttle response. I was wondering about a modified cam to reduce off-idle response a little. not a lot...but just a little would be nice IMO. maybe that changes as one adjusts to the bike?

Just a follow up on my post regarding easy wheelies in first and second. When I softened up the suspension on my R it took care of this problem. I consider it a problem because it would come up very very easily at a light just taking off so much so you could steer or brake if needed. It will still loft easy but now I have to give it throttle very very quickly to give it abrupt acceleration which works the suspension damping quick enough to prevent it from absorbing the weight transfer.

I don't understand the wrist position problem. Do not most people walk the throttle so that their wrist is always straight unless they are in the twisties of course?
I don't. I'd be doing it all the time. I'm not sure that would be safe, but maybe I haven't thought it through very well. The bike has such an incredible torque curve, I just don't shift all that often - which means I'd be walking the throttle all the time.

This is actually a bit dangerous and frowned upon by the local authorities as an unsafe maneuver. The reason for this is that it becomes increasingly difficult to fully close the throttle of you walk your hand around the throttle. I'll happily kink my rist to keep the throttle open at highway speeds in order to be able to close the throttle with no trouble. Mind you, this "kinked" position is still much more comfortable than the position I have to keep on my Yamaha FZ6 at the same speed. Image the same on a true sport bike with clip-ons.:eek:

I just "de-modded" the bike. Driving on poor roads (pot holes, rough surface) can be scary with this mod. You start bouncing pretty bad and you can imagine what happens to the throttle. Its good for freeway cruising (or the track), but not good anywhere else.

I believe I'm gonna do this mod - I have to twist my wrist bigtime to get to WOT and I don't like that...

The bike doesn't seem too touchy at all to me though, I don't relate to what others are saying.. Why would the Speed Triple, which is surely torquier than the Street Triple, use a throttle tube that makes for a shorter throw than the Street Triple and ride fine that way? I don't get it.. I would think that if the Speed Triple is manageable with that throttle tube, than the Street Triple would be even moreso...

I like giving the throttle a good twist - I wouldn't want the throw any less than it is on my Z1000 (talk about short-geared and twitchy throttle response in 1st gear!) , but I don't like having to adjust the position of my right arm to get enough of an angle to get WOT on the Street Triple..

I'm having a 15t front sprocket installed here soon too - that and some CRM pipes and I'm gonna be good to go I think =)

BTW, is this 1050 throttle tube an easy mod for a person with no mechanical skill to do? Or should I let my mechanic do it?

thanks!
