The Jimmy Twister is the ultimate in smooth throttle action.

SKU: 25-200 Categories: ,


G2 Challenge:  Increase throttle response and decrease throttle rotation (less turn) for 2 strokes.

G2 Solution:  The 2 Stroke Quick Turn System.

The 2 Stroke Quick Turn System consists of the ultra-smooth G2 tube with Delrin inserts fitted with a throttle cam (or “pulley”) over 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 quite noticeable, so a 10% increase will make a significant difference!  Also included is a modified Domino throttle housing that provides essential inner clearance for the oversized quick turn tube.

Increasing the size of the throttle cam will 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.

G2 Key Points:

  • Quick Turn tube machined from 6061 aluminum in the USA!
  • Housing manufactured by Domino of Italy with modifications machined in 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 up to your bike’s stock cables.
  • Slide one of our Domino grips (sold separately) or your grip unto the Quick Turn Throttle Tube.
  • Removable end cap for simple handguard installation.
  • Installs in minutes!

    If I could give this product 6 stars I would. This is one of them must-have items for each bike I own. Helps me keep my elbows up while riding. The build quality is outstanding, absolutely zero complaints.

    For anyone that has limited wrist movement like myself due to a wrist injury, the quick turn system is the ticket. The throttle is so smooth and easy to control no matter what the conditions are. Makes riding so much easier and comfortable due to the fact that you can stay in good form and posture. No more elbows hanging down near the foot pegs trying to get to wide open throttle. Five stars is really not enough for this. I would give it a “TEN”. Thanks G2 for coming out with such a great product!

    Just what I was looking for. Twist reduced just enough that I can get full throttle without my wrist going over center. My 1st day of test was a mix of very tight and slick single track with some wide open sand washes in between. Throttle control just off idle was great and then when it opened up instant full throttle. Build quality is outstanding. Should of made this purchase sooner.

    This is one of those “must haves” for my bike. Racing harescrambles and your body is up and over the bars, this helps get to WOT much easier!

    I ordered a similar product made by G2 when I installed it I glued my grip to the throttle tube and the glue seeped through the breather hole at the end of the tube and sat over night like this in the morning when I went to ride I went to grab a handful of throttle and it was completely froze up. Needless to say I ruined the throttle tube removing it. I called G2 to see if there was anything that they can do. First they corrected me and told me the one I ordered was not the best application for my bike as it is a 2-stroke and I needed the quick turn. This product was twice the price of what I originally paid for the first one that I destroyed. G2 told me that this mistake could have been avoided if I didn’t put any glue in the grip before installing it and taping over the hole at the end of the tube.
    THEY SEND ME A NEW THROTTLE TUBE FREE OF CHARGE. Not only that but a better one. You guys are awesome!!! And the best part is this is an awesome application for any two stroke bike. THANX G2

    I put this throttle on my ’82 Honda MB5. It’s only a 50cc, so needless to say it has to be run at full throttle at all times to keep it in the powerband. I was tired of twisting for miles with the stock throttle, so I tried one of these G2 units.

    It’s awesome. Easy to install, all of the important parts are made out of metal, and it has significantly less twist than the stock throttle. Due to the reduced wrist movement, my throttle response is much faster and I can now pop wheelies on my 50cc! I was not able to do this prior to installing this throttle.

    Easy to install, with the exception of the rubber cover from the stock unit. Very sturdy which is the attribute for which I bought it, unlikely to damage the tube. Gives the bike a snappier feel as to be expected when the WOT distance is shortened. Happy with this add-on.

    Love this product! I am totally surprised. I ride in the mountains on rocky trails; the first significant improvement I noticed was when going up steep rocky trails was the required throttle pull back to throttle demand ratio was substantially reduced. This made it easier to keep the engine at the optimum RPM for climbing. The product was easy to install. And the original rubber boot cover fit the same.

    I have a bad wrist , this throttle eliminates the hand fatigue I was experiencing with the stock throttle .

  12. Rated 5 out of 5


    Does exactly as describes, quicker turn and a high quality product. I have a stiff wrist and this throttle makes it much easier to get full throttle without the need to adjust my grip. The Jimmy Twister makes if feel like it’s on roller bearings. Nice product.

    This is definitely a MUST for all expert and pro riders who want that instant boost of power at the control of your wrist. Made a huge difference in my aggressiveness when it comes to passing people😊
