Custom Throttle Tube Builder for Yamaha

BUILD YOUR OWN Throttle Tube or Throttle Cam System with cams specific to what YOU need for your Yamaha! Experienced riders know that as track conditions change, so does the level of throttle control difficulty to put power to the pavement, or even dirt for adventure riders! Need a quick cam on your R7 for the next track day?? How about a control cam for that Tenere 700 when things get a bit more technical? Why not get a stock ratio cam so you can always return to that OEM feel? The G2 Custom Throttle Tube Builder allows YOU to buy as few or as many of our available cam ratios as you wish!

The G2 Custom Throttle Tube Builder for Yamaha offers different cam selections depending on the model. For most Yamaha models, the quick and stock options are circular cams, while the control, or “Tamer”, cams have a progressive shape. This “progressive” (non-circular) ratio between throttle grip rotation and power delivery can give you a huge improvement in control! As the power is rolled on, you will find it far easier to modulate traction – especially in the turns! The cam size increases, or ramps up, after ½ throttle to keep overall rotation near stock rotation. Whether your goals are faster cornering, less wheelspin, quicker response or more finesse on those technical trails, the G2 Custom Throttle Tube Builder for Yamaha allows YOU to choose the best cam ratios for YOUR riding and/or racing!


QUICK – for CLOSED COURSE COMPETITION competitors seeking a quicker action throttle. These throttle require less rotation and make it easier to reach full throttle while leaning left. A quicker throttle will cause the engine to accelerate at a faster rate per hand position as compared to stock. These cams are NOT FOR HIGHWAY USE. Use of these cams on highway can cause INJURY OR DEATH!

CONTROL – this gets tricky! For most riders seeking to decrease “Throttle Snatch”, or jerky characteristics of the modern fuel injected motorcycle, our 20% reduced cams (marked 400 typically) seems to work best. However, this may differ based on motorcycle power characteristics, track / road conditions and, most importantly, the rider’s level of throttle control prowess. Many riders like to also get the stock ratio and one cam in between to “fine tune” throttle control.

The Custom Throttle Tube Builder for Yamaha is based around the unique G2 proprietary interlock design. This allows interchangeability between the throttle tube and several cam ratio options for most models. The G2 throttle tube has Delrin self-lubricating bushings pressed into each end. These bushings eliminate aluminum-to-aluminum contact and galling which is common on many aluminum throttle tubes. Best of all, they provide a “buttery smooth” feel comparable to a ball bearing throttle (but without the ball bearing maintenance)! The tube has a knurled area allowing solid grip adhesion. Just install a high-quality Domino Racing Grip (or any other “non-lock-on” dirt bike brand) and you’re good to go!

  1. Dinko

    Works as advertised, but theres too much free play in the id to the handlebar. A tighter fit would be much better.

  2. James T.

    The G2 throttle tamer works well on my Tenere 700 to smooth out the throttle response.

  3. DEAN

    Definately smoothed out response at low speed in traffic for my 2020 MT07, Still not perfect, but definate improvement. Well worth money

  4. Charles

    Easy installation, smooth operation.

  5. Mike Partain

  6. Richard L.

    The product has smoothed out my 2009 Yamaha FZ6 throttle response, especially off idle. It’s much more enjoyable to ride and safer too, less jerky mid corner. Thank you for a great product!

  7. Anonymous

    Well machine

  8. Andrew

    Extremely well-made part, did exactly what I had hoped, fit and finish were as good as could be.

  9. Craig A.

    Just had to trim about 10mm of the end to fit my FZ10- no big deal!
    Easy install- very smooth now with the 1000cc bite still there at the top.

  10. Rikard Marchall

    An amazing product. Finally, I can control even slow cornering.
