Not for me.

Fits right and easy to install. It doesn't stick but its not smooth like plastic. Metal on metal just isn't as snappy. Not worth the buy in my opinion. I'll replace with OEM.

Fair price, excellent quality

I must say that this is a great tube. It has held up well so far and is super smooth and easy to twist!!!!

Awesome replacement tube - one warning

It goes without saying that the Pro Circuit throttle tube is a top notch replacement piece, leaps and bounds better than the stock plastic tubes. The finish is perfect, and the tube is as light as plastic. One note: make sure you leave a tiny bit of space between the end of the tube and the bar end, otherwise (especially if your bars have the small rubber end pieces) the tube and bar will rub together, causing the tube to stick and not turn freely. I struggled with this for a while before realizing that pushing the tube all the way inward on the bar was stopping it from moving freely. Otherwise, very happy with my purchase.

Great Product

Perfect fit with no issues. It is much stronger than the plastic stock piece and has a smoother feel. Great replacement once your stock tube wears out.

Great Throttle Tube!

I busted my stock plastic throttle tube on my YZ 250 and went with this aluminum throttle tube to avoid replacing it again. Super crisp throttle response, love it!

Can i use this on my kawasaki street bike?

Unfortunately Pro Circuit does not offer one of these throttle tubes for your Z1. These are model specific and unfortunately I do not know if any of them would be a crossover to work with your model. What you may want to do is contact Motion Pro directly as they have complete throttle housings and can offer custom cables for almost any application. This may be your best option to help clean up the controls for your bike. Motion Pro can be reached at 650-594-9600 or you can visit their website at

Does the pro circuit throttle tube reduce the amount of turn you need to receive full throttle?
MotoSport Staff
1 year ago Location: Portland, OR, USA
No, this will replicate the pull of your stock throttle tube.
Over 9 months ago Location: Eugene
No, it is a standard tube, just better material. There are other systems out there that reduce the amount of throttle turn.
Over 9 months ago Location: Pickens, SC 29671, USA
yes it is much smoother than stock

Will this fit a after market mottion pro thothole housein ?
MotoSport Staff
Over 3 years ago Location: P+RTLAND
I'm assuming you are still running your stock tube with that housing set up and this tube is built to OEM specs so you should be fine.

Are all throttle tubes 7/8?
MotoSport Staff
Over 3 years ago Location: P+RTLAND
Yes, all bars (stock or aftermarket) taper down to a 7/8th bar where your controls mount. Otherwise you would have to put on all new controls if you bought oversized bars.

Does this throttle tube come ready for bark busters or do you have to cut the ends off?
MotoSport Staff Expert
Over 5 years ago
No this full billet throttle tube is solid on the end of it. You will need to cut or drill to accommodate the hand guards.
