Doesn`t anyone else have a problem twisting the throttle all the way on their XB?

I always have to regrip it, and then twist all the way.

I`m gonna look around for a shorter pull throttle.

I've had to do that on my Yamaha. Drives me nuts. I've test the throttle on a Buell and it's the same way so I think it has something to do with all bikes. Parents Harley's are the same way.

I've heard of this but not noticed it myself.
The throttle on my XB12R rotates about 1/2 the way around the bar-same as my Sportster and KLR650 as far as I can tell.
Might be your grip position.
I've got to get different grips on the Buell & ESP. the KLR-my hands go numb.

Yep I'm wrong 1/4 turn.Sorry.

I think most sportbikes have 1/4 turn throttles. Some aftermarket companies make a little sliver of poly that you slip into the pulley part of the throttle barrel (under the pull cable) to make a 1/5 turn (approximately) throttle. Have one on the SV; makes a refined throttle hand necessary, but also easier to get on WFO while hanging off to the left.

Maybe its just my wrists, getting old and don`t move like they used to.

i would also like to see a shorter throw. if it were 50-60% of the current throw it would be perfect or me.

I'd like to see a shorter throw as well. I do the same thing I gotta wrap my hand twice to get WFO.

I would settle for about 80% of the twist I have now on a 12R. I can get to WFO from a regular position but I have to drop my elbow WAY down...

Well i`m glad to see its just not me.

I have a few quick pull throttles from my MX bikes laying around. I`ll see if i can make one work.

Keep in mind, that if you go crazy shortening the throw, fine adjustment of throttle will become quite difficult.

Thats true, i really was just looking to short the pull maybe 1/2".

I rode a couple of other bikes last week and the XB pull is definately longer by a good amount.

I’ve got the same issue with my XB throttle travel. Its just too much. There’s been a few times where I thought the bike was not picking up like it should only to find I had to wrap my wrist further around and away she went. Trying to maintain a grip that can achieve full travel and fully closed like when squeezing the brake and blipping the gas between down shifts is a distraction I’d rather not have to deal with.

I think, that if you mark the throttle and the switch housing and take a careful look, you'll see that we're only talking 1/4 turn throttle movement here.

I know it is on my S2 and was on the SV. I'll check the XB tonight.

1/4 turn is a good compromise between amount of movement necessary and sensitivity of the throttle. I.e. it's less likely to "jump" on you with just a small change in position. Much easier to be smooth that way.

Why not fit a 4 wheeler thumb throttle if you need less travel?

Because the movement of the bar may impart input to the throttle.

Yep; 1/4 turn throttle on the XB as well (as stated by Unibear above).

One thing I do to minimize wasted movement, is first to properly adjust the throttle cables .

Then, I grab (grip ? : )) the grip so that when my wrist is at neutral, the cables are taut and the motor running *just* above idle - the sweet spot where you can roll the throttle on smoothly without the motor "coughing."

I find that that allows me to use the majority of the throttle movement without shifting my grip. It's a bit easier on the SV with the 1/5 turn throttle, but for street use I find 1/4 turn to be a good compromise between movement and smoothness.
