Product Description

G2 Challenge:  Offer one throttle set-up for best overall performance in all off-road conditions.

G2 Solution:  The Throttle Tamer.

The Throttle Tamer incorporates a non-linear ratio between hand throttle rotation and carburetor or throttle body opening.  The “pulley”, or as we call it, “cam” pulls the throttle cable as the rider rotates the grip/tube.  By altering the conventional, circular shaped cam, a vast improvement in control is achieved.

The Throttle Tamer has a cam with a reduced radius initially, which requires a slightly farther rotation to achieve the same carburetor or throttle body opening position as a stock throttle.  This slightly longer pull makes a HUGE difference in control as the power is rolled on and the rider searches for traction.  The radius increases or “ramps up” after ½ throttle to keep overall rotation requires to reach full throttle at or near stock rotation.

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 ratio varies per model based on best suggested ratio for the machine’s power characteristics.
  • Fits inside the stock throttle housing to stock cables.
  • Slide one of our Domino grips (sold separately) or your grip unto the included Throttle Tube.
  • Removable end cap for simple handguard installation.
  • Installs in minutes!

    Performed EXACTLY Like Advertised – Great Customer Service Too! I actually had my KLX450R up for sale to downsize to a 250 due to the abrupt throttle response in the tight stuff as well as tired hands and arms. The G2 Dirt Tamer totally smoothed out the “hit” making my bike much more controllable, able to maintain traction and a pleasure to ride. Super fast shipping and fantastic customer service too. I highly recommend G2.

    Works great ! I love my Husaberg 450 now . Very smooth with the G2 Throttle Cam , 400 cam . Before the 450 was a handful in the single track ,now its very smooth !

  3. 5 out of 5


    Excellent! My feelings on it are pretty positive. I currently have the 300 cam on it and I am thinking I wont even try the 400 for a while. My bike is a 2011, so no “snatchy” throttle like earlier models. I did have about 3000 miles of off road with the bike prior to install and now have about 200 after.

    Pro- it does help a bit for the off idle creeping. Here again it was not excessive prior to install. where it shines is standing riding (which I do a lot of) in the rough stuff, if I am being beat around and twitching the throttle a bit-its not getting herky-jerky.

    Con- really not any “cons” it does take a little getting used to when on gravel roads and doing a lot of twisting in and out of the turns. Gives it more of a abrupt power band feeling (which is fine). I assume it is due to the cam design pulling more cable after a 1/3 turn or so.

    Fit- was really really nice ! I owned a fab shop so I am a little picky on fit and finish- these guys got their act together ! excellent workmanship – I mean EXCELLENT !

    Would I recommend it to others – Yes , but like cool aid flavors (ie: motorcycle brands/oil/tires) every one can make their own decision based on their own experience, I am just stating my experience and satisfaction with the product.

    We ride year round, mostly dirt and adventure dual sport riding between Nevada-Colorado and I like to promote good products.

    I trail ride in the mountains of West Virginia and the G2 Throttle Tamer has made a significant difference in controlling my KX450 on tight trails. It took me a couple rides to get used to the shift in cable pull that changes at about about 1/3 twist. It is not that the bike takes off like a power band kicking at 1/3 throttle, but does change.

    The quality of the throttle tube is top notch. It took about 20 minutes to install and fit perfectly. I highly the G2 Throttle Tamer this to anyone trying get more control over a large bike.

    Installed the Throttle Tamer on my ’09 TE 450, best improvement to the bike I’ve made so far, made the bike much more controllable on tight trails and “whoops”. Total install and adjustment took about 1/2 hr. This is a great product! and its made in the USA!

  6. 5 out of 5


    I have installed two Throttle Tamers to date; both on KTMs. My 990 Adventure has very poor mapping coming off idle making it “snatchy”. My KTM 250 XCF-W, though carbureted, utilizes an aggressive accelerator pump with a short throw to wide open. It too is “snatchy” coming off idle. Hard to hold steady throttle at very light engine loading. In both cases the Tamer eases this behavior. Does not “cure” either bike, but it helps noticeably. They are extremely well made and very easy to install.

    My crf450 was just too snappy for me, especially offroad. It was just too much work and would wear me out. Put the g2 on and it’s heaven. the best mod I’ve put on my bike and you can swap cams in minutes.

    Highly recommend.

  8. :

    I am really happy with the Dirt Tamer. It smoothened out my YZ250F’s throttle tremendously but the bike doesn’t feel any slower to me. If anything I am a lot faster now because I have better throttle control. It will be the first modification I will make if I decide to buy another dirt bike.

  9. 5 out of 5


    Smoothed out the throttle action on my KTM 450EXC, making it far less physically demanding to ride – I like this product.

  10. 5 out of 5


    This product is great!! Well built and does exactly what it says it would do, tame the throttle to a manageable point!

  11. 5 out of 5


    Bought this for my 2012 KTM 250-XCW. I have been running the green spring in it because the “hit” with the yellow or red was simply too difficult for me to handle. After adding the Dirt Tamer, the green spring now seemed way too tame but adding the red spring and WA LAH! The hit is much smoother until I give it a good twist and then it has they great power I was missing with the green spring. I know everyone raves about how great these things work on the fuel injected 4 strokes but it really works wonders on the 2 strokes as well. Best money I have spent on my smoker!

  12. 5 out of 5


    I bought one of these for my Xr600 as it had a light switch throttle (eg; on and off) it worked a treat in taming it, now its smooth and controllable in all conditions…

    I love it….

  13. 5 out of 5


    I have used Dirt Tamers on a 2012 Kawasaki KX250F and on a 2013 Yamaha YZ450F and they work great at smoothing out the abrupt low end power of both bikes.

  14. 5 out of 5


    Just plain works!

  15. 5 out of 5


    Great bit of kit, shipped right away and arrived in UK within a week, will definitely buy from G2 again. Thanks!

  16. 5 out of 5


    I got the Tamer 400 cam for my 14′ 350 XCF-W and this thing is the bomb!
    No more snatchy throttle and so much more smoother from idle to 1/4 throttle.
    My bike is so much easier to navigate the technical stuff and lifting the front tire
    is much easier, no more whiskey’s for me.

  17. 5 out of 5


    Great quality. Great product. Love it. Allows for way more control in the right stuff and more traction when you do twist.

  18. 5 out of 5


    this product was recommended by a friend who is very well versed in all this dirt bike.

    makes riding my 2014 KTM much more enjoyable and even came in Orange

  19. 5 out of 5


    read the reviews and decided I had to try this. It arrived and in ten minutes it was on my ’08 WR250R and ready for a test ride.

    After 45 miles of riding in conditions ranging from pavement to loose gravel, deep sand and near switchback turns with deep loose gravel what an amazing difference!
    No more “off/on” switch for throttle control. It makes the bike so much smoother and easier to control in tight, low speed and low traction situations.

    Exactly what I was looking for – thanks for making a great product that works as advertised.

  20. 5 out of 5


    Use it on my ktm 690 r, which I use almost exclusively in the dirt. Great bike but if is a bummer trying to crawl thru rock gardens…the snatch was bad news.

    The Tamer made a massive difference. So much more control and the quality is fantastic.

    Installed this on my 2008 Super Duke 990 R to help smooth out the snatchy throttle response at low speeds and it did just that. However, I also lost a bit of the quick throttle response that I enjoyed both coming off the line and after changing gears. Rode with it for about two weeks and did a bit more research and discovered the primary cause for my particular bike is due to the emissions control system (O2 sensors and mapping). Decided to remove the throttle tamer and am currently working on the mapping. If it’s still a bit snatchy, I’ll consider ordering the 200 or 300 cam. Definitely recommend this product, does exactly what it says, but also recommend getting it with more than one cam.

  23. 5 out of 5


    The Dirt Tamer is a great product! Provides great control in the tight technical areas.
    Very good quality, smooth as silk. Customer service at G2 great, always willing help. I have a Yamaha WR250F and asked them if the 400 cam that comes with the DT would be to tame. At no extra charge they included the 300 cam. Great product! Great company!

  24. 5 out of 5


    I have a ’09 KX450 and needed a smoother hit off the bottom for trail riding. The throttle tamer did just that. The initial hit is gone and replaced with a even response. This makes controlling the bike easier and not nearly as tiring when riding tougher trail sections. I should not have waited to purchase. Anyone who rides trails on a 450 will benefit from this product. Once you get past the first 1/4 to 1/3 throttle opening you are back to normal throttle and hit. Installation was as simple as replacing any throttle tube. I see no downside to the tamer.

  25. 5 out of 5


    Bought this for my Husqvarna te300. It helped a lot. It took the initial hit out by giving me a little more control of the throttle. I do not have to buy the flywheel now.

  26. 5 out of 5


    Great product!!!! I put one on my fiances 150R and she was able to control the bike and trail ride. She rode the same bike week earlier and looped it twice, she refused to get back on it. Now she wants to go trail riding again.

    Customer service is excellent my throttle tube was out in the mail before I got to pay for it.
    Thank you Sam for making our thanksgiving weekend fun and safer.

  27. 5 out of 5


    I’ve installed the tamer in my FE570. The response is very smooth taking the punch of the big engine and the EFI off. It allows you to concentrate on driving.
    Very nice.

  28. 5 out of 5


    This makes my KTM 500exc a better ride, I feel less beat up on the trails and the response is predictable and smooth.
    Thanks for the great product and fast delivery.

  29. 5 out of 5


    I ordered this for my 2013 Ktm 450 XCW and it was exactly what I needed.. The stock throttle on the 450 was just to jerky and this really smoothed out the power delivery and provided me with additional traction as a result of less wheel spin. I really feel like I am in much more control of the bike now… I would highly reccommend especially for those of us who have to have the big 450’s and 500’s.

  30. 5 out of 5


    The Dirt Tamer throttle tube worked just as advertised. My 2013 WR450F Yamaha has much smoother throttle response at low speeds now. Easy to install instructions as well. Would recommend to all “Senior” riders who enjoy trail riding.

  31. 5 out of 5


    Worked great on my YZ250. Made first gear a little more usable going through rocky sections, and noticed traction control is much easier in loose and muddy sections. Hill climbs were also more manageable. The only thing I noticed was a little less pop coming out of some corners, but for trial riding you can’t beat this product. 5 stars.

    • :

      Thanks Tony! The Dirt Tamer comes with a 400 cam, which begins about 20% smaller than stock. You mentioned a “little less pop coming out of the corners”. If after giving the 400 cam some more time you still feel this way give us a call. We have a 200 (-10%) and 300 (-15%) cam that both offer more control than stock, but a bit more aggressive down low than the 400.

  32. 4 out of 5


    Very nicely made!

  33. 5 out of 5


    I first purchased a Tamer for my 2009 KX450 and was very pleased with how it helped the initial hit off the bottom. So I just purchased one for my 2014 KTM 350 xc-f. The initial throttle hit is smoother but it does not take much of a twist to obtain the hit when needed and that is important. I didn’t want that sluggish feeling that requires a lot of twisting the throttle and the Tamer isn’t that at all.

  34. 5 out of 5


    Works great. Really helped this old guy out in tight trails and setting up for logs and such.

  35. 5 out of 5


    This is my third purchase of a Throttle Tamer and it made a huge difference on a KTM 990 Adventure and a KTM 990 Super Duke. It wasn’t quite the big improvement on a KTM 690R but then again it wasn’t needed as much as on the 990’s. I definitely recommend this product and the folks at G2. Bud

  36. 5 out of 5


    I just bought my first 450f. I have a 2014 YZ450f. For the last 5 years I have been riding YZ 250 two strokes. Going to a fuel injection bike, the first thing I notice is that it was jerky of idol in the woods.

    The G2 throttle tamer solved this issue. Great product and great quality.

  37. 5 out of 5


    This is a fabulous product. The materials, design, fit and finish are top-notch. It also works just as advertised. I converted a YZ250 from an MX bike to a tight woods bike, and tried everything to tame the hit, and make it less likely that I’d whiskey-throttle myself into a tree over every little bump. I messed with the jetting and timing, added a flywheel weight, and put on a Gnarly pipe. None of it really helped that much (except the timing, which killed the top end).

    Finally, I went with the throttle tamer. It’s perfect. The power is still there, but precise manipulation of the throttle at lower speeds is much easier. Blipping the front tire over logs is now easy, instead of terrifying. And if I just roll my wrist a little further… all the power is there, ready to launch me forward when I want to rip.

  38. 5 out of 5


    Bought for my KTM 500. Smooth action and sturdy. I’m glad I purchased. The response is a lot better.

  39. 5 out of 5


    Got the straight up Dirt Tamer w/ 400 cam. Took a very long trail ride with various terrain over the weekend. It calmed my TXC 310 down enough to putt around slowly without the jerky throttle. My hand didn’t get as tired as it normally did. Was able to slow down and control the bike easier. Still had the get up and go when I needed it. Worth it investment in my opinion.

  40. 5 out of 5


    KTM xcfw 350 2012. So the efi throttle snatch has gone. The roll on is way preferable in the tight northwest forest trails.

  41. 5 out of 5


    Running the Dirt Tamer on the new 2015 KTM 500XCW. Super smooth and excellent power delivery for this bike.

  42. 5 out of 5


    installed it on a 14 husky txc310r, really smoothed out the power delivery. would recommend it

  43. 5 out of 5


    Installed on a 2012 YZ450F. Mellowed out the abrupt off idle throttle response. Great design and well made product.

  44. 5 out of 5


    Fitted this to my 2103 KTM 450 exc.
    Found it gave a massive improvement in slow speed control and through the very rutted sections out on the trails. Easy to fit and silky smooth operation. Great product – highly recommended.

  45. 5 out of 5


    I put one on my YZ250FX and it was even more noticeable than my KTM300. It really make the super short/quick throttle easier to control. Worth every penny!

  46. 5 out of 5


    I installed on a 2015 Husqvarna 501S with the 300 cam, and now the tight singletrack is a breeze to negotiate. The throttle body is a great product!!

  47. 5 out of 5


    Fixed the snatchy pull on my 03 EXC 525 OEM throttle and made a huge improvement in the slow sections.

    I’m getting one for my nephews XR600. So he can experience smooth power

  48. 5 out of 5


    Worked wonders for me. Does just what it says it will!

  49. 5 out of 5


    Great product, awesome customer service. Installed on CRF250x.

  50. 5 out of 5


    another happy husky te 450 rider… easy install, but then put the old tube back on to warm up… reinstalled trailside just before a boghole and nasty muddy climb…the improvement was felt immediately, with better drive and the bike steering better, all with no adverse side effects i could find even on the open stuff…amazing !!

  51. 5 out of 5


    Great Product! I bought the G2 Throttle Tamer for my KTM 200EXC which I mainly ride in the Eastern woods. I had already installed a flywheel weight and tuned the power valve way down but the hit was still pretty brutal and made finesse moves over logs and slick trail areas really difficult. Now with the G2 installed it is like a whole different bike! I can control it like my Sherco Trials bike (well, almost) in slow obstacles but when I need the hit just cranking the throttle further gives me all I need. Thanks G2!!!

  52. 1 out of 5


    Dirt tamer = same radius as stock (measured) i.e. no difference (Yamaha YZ250F) Deceptive!
    If you want a truely slower initial pull get the $110 “System”. It does have less friction on the bar though, but, less friction does not equal a slower pull. 1 star only because ap forced me to select.

    • :

      Hi, could you tell me what number/letter is engraved on the silver cam? It sounds like you received the wrong part. Thanks! Gary

  53. 5 out of 5


    Third bike I have installed the G2 cam (300) on. I won’t ride single track without it.
    Tank foam is next!!

  54. 5 out of 5


    These throttle tubes are fantastic! I put one on my husky and will never go back! Vary reasonably priced and love the removable end cap or the roller bearings for smother response!

  55. 5 out of 5


    If you are looking for more throttle control this is a must. Better throttle control better traction. (Y)

  56. 5 out of 5


    I have been a 4 T guy for years, but went back to a 2T a few years ago. As most 2T riders know, its all about throttle control. The Dirt Tamer helps a lot!

  57. 5 out of 5


    I bought this for my 2015 husquvarna fe501s. And I gotta say, it is the best mod I could possibly imagine for this bike. The power is so abrupt it is almost impossible to control on hard hill climbs, and is even annoying when just trying to hold a steady speed as the on off feeling rocks you back and forth, but this made everything so much better. Big thumbs up, easy five stars.

  58. 5 out of 5


    Very nice piece of gear and it works. Would absolutely purchase another one of these if I had another bike. Would recommend to anyone who wants to take the twitchiness out of their bikes throttle response.

  59. 5 out of 5


    Better than expected! Not a band wagon guy! But my KTM 500XCW was so hard to ride in the slow tight stuff I got desperate. Works like a dream! Should be standard equipment in my opinion. Was reluctant that it would work at first, but was immpressed from the start, so much so I had a herd time getting off the bike. I had cut a few rides short in the past out shear disgust and frustration. Thanks G2 oh and KTM should thank you as well cause I was pondering a for sale sign if I could not tame the treail manners of the 500. Cheers, Steven
