The Jimmy Twister is the ultimate in smooth throttle action.

SKU: g2-stock-tube Categories: ,


G2 Challenge:  Create a bullet-proof throttle tube with smooth action.

G2 Solution:  The G2 Throttle Tube.

The G2 Throttle Tube consists of the ultra-smooth G2 tube with Delrin inserts fitted with a 100 throttle cam that is the same size as stock.  The throttle tube shares the unique G2 cam and tube interlock that allows the rider to update to a quicker turn or control cam, sold separately, at any time.  You are NEVER stuck to a ratio with G2!

G2 cams are interchangeable!  You are never “stuck” with a ratio that is not correct for your skill or track condition!  You can always go back to the stock ratio, quicker, or for most models several different progressive control ratios!  Cams may be ordered separately here, or consider the G2 Throttle Cam System that includes a tube and three cams – 100 (stock), 200 (10% smaller & progressive) and 400 (20% smaller & progressive).

All G2 Throttle Tubes come standard with Delrin bushings pressed into each end.  The durable, self-lubricating material prevents aluminum-to-aluminum contact for a buttery-smooth feel.  Using handguards?  No worries!  Just pop off the G2 Throttle Tube’s end cap for easy handguard or bar end installation!  The 6061 aluminum alloy is machined in he USA with a knurled area to keep your grip secured.

G2 Key Points:  

  • Proudly 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 – keep your quality stock throttle housing and cables!
  • Slide one of our Domino grips (sold separately) or your grip unto the G2 Stock Throttle Tube.
  • Removable end cap for simple handguard installation.
  • Installs in minutes!

    I bought this item and the 500 cam so I could easily switch between the stock configuration and a configuration that is radically “tame”. I suspect that I will be buying more cams in the future but since the shipping is so quick and hassle free (even to Canada), I am happy to do so. The workmanship and quality of this product is very high. You won’t regret this purchase.

    I have purchased 2 of these, for a KTM and Yamaha.
    Easy install, fits perfectly, no issues at all.
    Quality is awesome.
    Throttle is smoother than stock and the cam system works great. Makes managing the low torque RPM’s much easier.
    I would not own a bike without one!

    Installed this, with the 400 cam, on my Gas Gas EC300. Takes the hit out of the initial portion of the throttle opening, making low speed/low rev riding easier. Very nicely machined, easy install, super smooth…and really fast shipping (to Canada!).

    I have the stock cam. The product is well made and I have the option to use another cam later if I choose.

    My son loves it I installed it on his KTM SX50. Very easy install, but be aware that you need the 125-250 throttle assembly. The original throttle is to small for the G2 cam.

    I have this on my KTM 350 with the 50% cam and it is the only way to go!

    The throttle slides so nicely and makes the bike so much better!

    I did a Youtube review: http://youtu.be/6n_C_wJWtHU

    This is for my 2012 Gas Gas EC300, seems to be perfect, had no issues receiving the product or installing the product and it’s much much smoother to twist the throttle over the stock unit.

    Excellent fit and quality built, and a nice addition to my WR450F. The self lubricating bushings make for a smooth twist.

    I contacted g2 to help me find a more comfortable grip solution for my rather large hands. I didn’t have enough width at the grip and i wanted a larger diameter grip. G2 hooked me up with a longer than stock tube, which i combined with a set of Oury street bike grips. Perfect! My big hands are now much more comfortable. Thanks for taking the time to help me in my unique situation.

    Item as described. Super easy install for replacement of my stock husky te510 throttle tube. Would definitely recommend to a friend.

  13. Rated 5 out of 5


    I never thought much about a throttle tube being much of an upgrade, but the self lubricating bushings give a real smooth and snappy feel to the throttle. Great product, I will likely buy one for each of my bikes and any future bikes that I buy!

    Broke the factory throttle tube on my 2012 WR450f. Replaced it with a cheap plastic tube. Whenever I pulled on the handlebars even just during a wheelie, the tube seemed to be sluggish and unpredictable. I replaced it with the G2 stock tube and wow what a change. The throttle is silky smooth and better than brand new. I highly recommend this product.

    Awesome replacement or upgrade to your stock throttle tub. Cam system makes it nice to adjust to your riding style and conditions. Very robust and smooth operation! I have one on all four bikes and back-up in the trailer when the crashes are too for any throttle!

    Bought this for my dr350 project. Fit and finish is excellent. Super smooth. Looks nice on the new bars. Too bad it’s hidden by the grip.

    Bought one for my 2006 Husky TC510, it was awesome! Super smooth and much better quality than the plastic stock one.
