G2 Quick Turn Throttle Tube

(37 customer reviews)


Increase throttle response while decreasing throttle rotation (less turn).


* Add the Jimmy Twister?

The Jimmy Twister is the ultimate in smooth throttle action.


G2 Challenge:  Create a quick turn throttle for increased throttle response and decreased throttle rotation (less turn).

G2 Solution:  The Quick Turn Throttle Tube.

The Quick Turn Throttle Tube consists of the ultra-smooth G2 tube with Delrin inserts fitted with a throttle cam (or “pulley”) approximately 10% larger than stock.  This translates into about 10 degrees less “twist” necessary to reach wide open.  To put this into perspective, a 3% change is noticeable, so a 10% increase will make a significant difference!

Increasing the size of the throttle cam can improve your riding in several ways.  First, your bike’s power characteristics will seem far more responsive – as you turn the throttle, your bike will rev faster than before.  Secondly, less overall rotation is required to reach full throttle.  This is a huge benefit to riders with limited wrist mobility.  In addition, less rotation allows you to more easily maintain a proper riding position with less elbow drop as you crank the throttle.

Keep in mind, the throttle “cam” are interchangeable.  You can go from quick to stock, or even a progressive control cam for slippery events.  The tube/cam have a unique interlock that allows the cams to quickly be changed at any time.

G2 Key Points: 

  • Machined from 6061 aluminum in the USA!
  • Self-lubricating Delrin bushings at each end of tube eliminate aluminum-to-aluminum contact and provide an ultra-smooth feel.
  • Included cam is removable and can be replaced with alternate cams (sold separately) to fine tune control.
  • Fits inside the stock throttle housing to stock cables.
  • Slide one of our Domino grips (sold separately) or your grip unto the Quick Turn Throttle Tube.
  • Alternate cam at 20% larger sold separately.
  • Removable end cap for simple handguard installation.
  • For the smoothest throttle action possible, try adding our Jimmy Twister Throttle Bearing!
  • Installs in minutes!

    The G2 Quick turn Throttle tube cam system for the KTM RFS works good But I want to go to a faster openning cam I mite give the 25 cam a try next time around I enjoy the harder hitting throttle responce I getting with the G2 throttle.

  2. Darrin

    I recently purchased one of your throttle tubes. It had the shorter turn cam. I went with that one because i hurt my wrist early on in the season. I just raced the last round of the senior national and took a 2nd. First time i used it and all i can say is wow!!! 100% happy.It makes my bike hit harder, a full second every time i grab it., it almost feals like i have a 3 horse power gain in the low end. $ for $ this is the best in the market thanks

  3. Veetwo

    The G2 quick Turn is a perfect match for the FCR’s on my KTM 950SER. I have instant throttle response & feel right at the grip with out compromising smoothness in tight areas & street use.
    money well worth spent.

    I’m really satisfied with the G2 quick turn throttle tube. Installed it in my KTM SDR and achieved the throttle behaviour I was looking for (noticeable quicker response without overdoing it). If the SDR were not so rough around town, would go to a .25cam. Will also install it on my other bike. Top mod, highly recomendable. Thanks!

  5. Travis

    I use the throttle tube for the smooth feel from the Delrin inserts. I use stock throttle cam. I would give 5 stars if replacement inserts were available.

  6. Bgavaza

    The quick turn throttle tube is amazing. Makes the bike feel more responsive. Great if you have a wrist injury with limited movement like me

  7. Olivier

    I decided to buy an throtlle with cams as I have some problems to ride smooth in small trails with the idea to use a quick turn cam on MX training.
    The reason I bought the G2 Quick Turn Throttle Tube is the the clarge choice of cams.
    machining of the cams is good.
    I bought a KTM typ because I was such it will fit my BETA. but now I have an orange spot on my bike 😉
    Shippment to France took approximatly 10 days.

    I bought this for my 08 KTM250sx-f. Very nice finish to the product and alot of detail and thought went into the design. I appreciate the removable end plug and the smooth operation of the bushings. It’s great not having to twist the throttle as far to get the same amount of power. It also fits the grip great and no worries about slipping. A more aggressive cam may be better for the two five ohs.

  9. Mathieu

    Best mod I’ve done to my bike!

    When I switched from ATV racing to motocross, my main complain was how far you had to twist the throttle to get it Wide-Open. I was always feeling like my hand wasn’t in the right angle. I even fitted a thumb throttle during a whole summer with very good result.

    When I found the G2 quick throttle with the 050 cam, I immediately loved it. Then I tried the bigger 025 cam which is the one I use for 3 years now. The very fast opening throttle suit really well my YZ250F power band and seems to reduced the throttle twist by half.

    The aluminum throttle tube with the insert is also stronger and smoother than the stock unit.

  10. Kenneth

    This is the second quick-turn I’ve bought and used with no complaints. Awesome product and a great company to deal with.

  11. Joel

    Installed the quick turn throttle tube on my KTM Duke 390, while the original was plastic rubbish these are high Quality, and the quick turn adds security to my driving when opening ful throttle, my wrist says “Thank you”

  12. G2 Ergonomics

    ….on Sunday 13 I was at the track, and I finally got to try the quick turn. wonderful! smooth operation and less rotation, just what I was looking for. my position on the bike is now improved, Because my elbow must not be more ‘bend down to open all the gas, and I do not have to regrip the knob., and the response of the engine is now more ready, though, now is a bit ‘less easy to control, but i think it’s just a matter of practice.The quality of the tube is very good, and i want to express my appreciation to you for sending me the right part quickly. I want to rewiew your quicktube Because he deserves it, And Also to take advantage of your offer of 20per cent of discount on the next purchase, but maybe the link in your email is uncorrect, and I can not rewiew. kind regards, and to thank you all for the great job.let me know, kind regards, thank you.

  13. Phil

    Quality piece, shame to hide it with the grip. Noticeable difference over stock. Now that I got used to do it, sorta wish it was even quicker. But the larger cam won’t fit on my bike.

  14. Matt

    Run this on my ’12 Kx450f. Quick turn definitely helps keeps your elbows up and makes the response incredible. Super smooth action with the delrin insert!

  15. Vinny V

    As others have already said, if you have wrist problems, especially with limited movement, you’ll LOVE the Quick Turn throttle! I have been running this on my previous 250s and just installed one on my new 450. Measuring the amount of twist on the 450, it’s right at a 1/8 turn of the throttle from idle to wide open throttle. Yet, it’s very controllable. It also makes you feel like you’ve just added a few more HP to the motor since you are riding closer to, or at, WOT! I can really rip right out of corners! Another plus is the customer service. Really, really great and accommodating people!

  16. Bill AuCoin

    Installation on my 2012 Husky TE511 was super easy. Delivery was quick and I appreciated the update emails regarding shipping. Instructions provided were very clear and quality of the product was top notch. Thank you G2, very professional.

  17. Rory Niquet

    Great throttle tube, used the yet unlisted version for my KTM Duke 390, I works a treat.
    Currently using the H100 cam for commuting, a nice controlled start with an extra kick at 1/4 turn.

    Very easy to fit, this tube has a slightly narrower diameter than the stock tube so get some new grips to fit at the same time, a squirt of graphite powder doesn’t go astray either.
    The team caught my second email after my purchase and supplied me with the correct model, hats off to them for that and a great product!

  18. sam howard

    Very easy installation.

  19. Garrett Foster

    Love this. First few laps I did not like it and was going to take it off because it was so smooth. I kept it on the rest of the day and ended up loving it. There is a noticeable difference with the 10% cam. I was able to clear a triple in a rythem section easier because the bike seems to accelerate faster.

  20. Christian

    G2 Quick Turn Throttle Tube
    I have this system on my RMZ450 -10 and it is the most important piece of aftermarket goodis I have


    the only reason I´m not given it 5 stars is that I would like it to have a even more quick response 20%

    I have broken my wrist´s a couple of times and have lost my power in the outer position (wide open) and the 10% have given me alot back but it could be more… please make it…..

  21. Jordan Reynolds

    @jreynolds453 – I am a Pro MX and SX rider. I just realized due to wrist injury that I was not getting full rotation of the throttle. I purchased two of the KTM tubs withthe bearings. 100% happy with the results. Thank You G2

  22. Matt Pietkiewicz

    Fitted a Quick Twist throttle tube to my 13′ KTM350sxf last night. wasnt really sure whether i’d like it but I went out to my local MX track today and can honestly say it is the best mod i’ve ever done. Best ride i’ve had in a long time, It makes the bike feel like it has 5 more hp off the bottom, and i found myself WOT around much more of the track.
    Hitting jumps from inside lines with ease where i would normally struggle a bit and have to rail the outsides.

    Save that $1000 on an exhaust system and get one of these.

  23. Jeff

    2 Quick Turn Throttle Tube – installed on my 2014 Duke 390.
    Easy install, fit and finish is great. Overall feel is very solid and can now get to the meat of the power-band of my bike in an instant.
    Great product

  24. Bjorn

    Awesome throttle tube. G2 Quick Turn with Jimmy Twister offers the best and smoothest throttle action of any throttle tubes I have tried. Excellent quality and worth every penny. I would never have thought that a throttle tube could make a significant difference but this one truly does.

  25. Nyall Engfield

    Fit great on my Duke 390, good quality machined aluminum and bearings. Fast shipping and they color matched the throttle to the KTM orange.

  26. jordan reynolds

    We have run these throttles and the roller bearing on four diff manufacturers bikes and both 250 and 450 on the Pro level for years. The best throttle tube, quick turn and roller bearing on the market.

      Wow! Thanks Jordan! Hard to beat an endorsement like that!

  27. Jugnuts

    Great product. Great for people with limited wrist motion

  28. Roberto Bajocchi

    Fantastic ! High quality and high functionality, the very best i can have .Thanks for this !!! significant improvement , less rotation , engine more ready , and also less dropping elbow to reach full open , that makes the ride more efficient , simply the best !!!

  29. Jahwann McIntyre

    very pleased with this product, I believe it is a must have for those trying to correct their posture and reach wide open throttle with less elbow drop. wouldn’t hesitate to buy again.

  30. Bryon

    I put a one on my 2015 WR250f with the 25 super quick turn cam. I have low mobility in my wrist and this has really helped with throttle control and getting her opened all the way up. After a few hour and a half long rides this has been a great addition.

  31. John

    I installed the G2 quick turn throttle, Wow. Much less effort on your wrist, and the bike feels more responsive. I instantantly did my personal best lap times on the track. Best and cheapest mod I’ve done.Very happy!

  32. Landon86

    This was purchased for my son who is a mini rider in GNCC’s and Full Gas Sprint Enduros. He has stated that throttle control is easier and much smoother. He can get into the meat of the two stroke quicker as well while maintaining consistent throttle control. We are very pleased with this product!

  33. Steve

    Installed G2 quick turn throttle on my 17 KTM 500 exc-f,stock throttle seemed like it turned way to far I and was kinda of a pain when standing the G2 turns quick and gets right to the power a lot faster,I had to take a small grinder to get rid of the stop in the housing that was no problem it works great.

  34. Steve Bouchard

    Excellent Product , Fast shipping worth the money by Far

  35. Abramsgunner

    Great product… works well on my ’09 KLX250S. The stock KLX tube has a long throw and you have to ‘re-grip’ to get full throttle. Quick turn lets you get all the throttle you want without changing hand positions. Takes a ride or two to get used to the change, but all grins after that. Price is a little high.. but quality seems top notch.

  36. Timothy McGee

    Best throttle tube we have run on any of our bikes. Helps my son get to full throttle quicker with out making the bike feel choppy. Made in America and great customers service!

  37. Corey Wilson

    Being a newer rider it was difficult to regroup and grab full throttle while keeping good from. After doing some research I found this kit along with the jimmy and viola!!! This will be on any bike I get in the future before a pipe!
