Product Description

The G2 Street Throttle Tamer Tube for Yamaha incorporates a non-linear ratio between hand throttle rotation and carburetor or throttle body opening. The throttle tube has a pulley where the throttle cable, or cables, attach. This pulley pulls the throttle cable as the rider rotates the grip/tube combination. By altering the conventional, circular shaped pulley into a “cam” shape, a vast improvement in control is achieved and throttle snatch is drastically reduced.

The G2 Street Throttle Tamer Tube has a pulley with a reduced radius initially, which requires a slightly farther rotation to achieve the same carburetor or throttle body opening position as compared to the stock throttle tube. This virtually eliminates the jerky “throttle snatch” especially evident in modern fuel injected street bikes. The radius increases or ramps up after ½ throttle to keep overall rotation required to reach full throttle at or near stock rotation.

The profile shape and ratio proven to be the best all-round solution for each model is used.

You will need a grip to install to your new Throttle Tamer. If your stock grip is in good condition, most may be removed and installed onto your Throttle Tamer. Check out our INSTALLATION section for removing stock grips from the stock plastic throttle tube, gluing grips onto the Throttle Tamer and installing the Throttle Tamer with your stock throttle housing and cables.

G2 has offered the Street Throttle Tamer Tube for over 17 years with tens of thousands of satisfied customers worldwide. We guarantee you will find this the best investment in control you have ever made, or you can return the throttle for a full refund! At G2, we stand behind our products and pride ourselves on the best customer service. If you have ANY questions about our throttle, please call or email (see contacts page). We guarantee a human will answer the phone or respond to your voicemail within one business day!

    I took my 2007 Yamaha FRJ1300 out for a long ride yesterday after installing the throttle tamer tube and wanted to say the results were astonishing. The bike suffers from very abrupt on/off throttle transition and is also difficult to accelerate smoothly with any degree of control and modulation. The throttle tamer tube improved the response dramatically, well beyond my expectations, especially for a $50 part. Thanks for the great product!

    Just a note about the G2. I ordered and received it for my 08 FJR this week. Yesterday I installed it. It is a real pleasure when an aftermarket product does exactly what it is advertised to do! No more ‘adventures’ going into turns due to the jerky application of power coming off 0 throttle. Starting off from stops is also improved 1000%. Just a smooth application of the throttle. I took the bike for a couple hour ride through the backroads of Connecticut and couldn’t have been more pleased! Thanks for a great product!

    I installed this throttle tube on my 2009 R1, which is infamous for having poorly set up fueling from the factory due to EPA emission standards. What you will experience is an abruptness when you open the throttle and a harsh lash when you close it, which is the result of the factory setting up the ECU to run the A/F as lean as possible to help with carbon monoxide output. Yamaha’s attempt at rectifying this quirk was the drive mode selector, which adjusts how quickly the throttle valves (and in turn how quickly the injectors ramp up for acceleration and slow down for part throttle) react to your wrist’s input, with the slowest setting reducing the harshness of the fueling the most, but the effect was still obvious in the slowest setting.

    I took this one step further with a G2 Throttle Tamer, which uses an elongated lobe on the throttle tube instead of the OEM’s perfect circle to slow the operation of the throttle shaft. Installation was simple and I’m happy to report my bike is much smoother than what it was. I still have to use the slowest throttle map, but I am no longer anxious to use higher RPMS in fear of that nasty lurch effect. This is the best $80 I’ve ever spent on a bike, and is much better than spending several hundred dollars adjusting the ECU either through a black box or reflash.

    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!

    I have the tamer fitted to my FZ6 S2, and although the difference it makes is quite subtle, it’s noticeable. It certainly does the job it’s supposed to, reducing the initial snatch of the throttle. I’m sure the only way to eliminate it completely would be to do a fuel remap, but the tamer sure helps improve things. The level of difference it makes will depend on the bike it’s fitted to. It’s a nicely made item, and is easy to fit even if you’re not particularly mechanically minded. All in all I’m pleased with it and would recommend it. The service from G2 was spot on, good communication and delivered to the UK within 10 days.

    Whilst the throttle tamer has gone along way to reduce the snatch on MT09 /fz09? and made the bike more enjoyable to ride, I found the circumference of the throttle tube was incompatible with the genuine YAMAHA heated grips and took a great deal of time and effort to make it fit.

    Got this for my wife’s bike. She’s small so when she held her bike open her shoulder would drop and it would throw off her balance. This is perfect to fix that. It delivers the power smoothly and it’s aggressive without being crazy power. She loves it and is ordering another one for her practice bike.

    Fitted this to my 2014 Yamaha MT-09 (FZ-09) Since fitting it the bike feels so much better. Throttle roll on is smooth and predictable as it should have been from the factory, I now ride in A-mode all the time and am no longer having to concentrate so much on throttle control. There is still a very slight jerk when first rolling on from a closed throttle but because of the cam at this point the throttle is open a lot less than it used to be so its a much softer and more manageable jerk and no longer upsets the bikes attitude like it did before. I can also confirm that the rotation required from closed to fully open is still just 1/4 so overall acceleration is just the same as it was before. The jerky throttle is now a thing of the past for me. Have recommended this to lots of other MT-FZ owners also.

    Makes a big difference. Much more control whilst cracking the throttle in the apex of a bend, and easier to match downshifts/upshifts. Also virtually eliminates that lurch we get when hitting bumps. Freeway cruising is much less fatiguing as the throttle is smoother in the cruising range and control is much better. Worth every cent. Quality is aircraft level. Domino grips are also very good quality.

    From ordering the G2 throttle tamer to delivery was 9 days which is great considering the distance it travelled to get to me and I was really impressed with the quality of the manufacture and the materials used which is far superior to the OEM part and fitting to my 2014 MT09 Yamaha took 15 minutes max.

    The difference in the ride quality is amazing. No more firing the throttle open every time I hit a bump in the road, no more jerky throttle on roll on and riding through cities in heavy traffic is now a pleasure. Cornering is now a science and not a lottery as I can now feather the throttle and put the power back down without any nasty surprises.
    The throttle tamer has made a good bike great.

  20. Bill – Aprilia RXV 450

    Almost uncontrollable off-road and miserable in traffic, low speed or on the freeway, but the speed, acceleration & power were astounding on the factory throttle tube which always put a grin on my face. All the above comments apply. Motocross was difficult and trail riding was all clutch slipping, starts and steady speeds were always a challenge.

    Now (with the G2 Tamer Throttle)… what can I say that hasn’t been said before? Starts on the street are great, modulation at speed is much more controllable – steady state is easy & lurches from uneven tarmac virtually gone – and best of all off-road is really fun and the Virginia City Grand Prix (put that in a search engine) was a blast. The aircraft grade aluminum is way sturdier than the stock plastic item. It is hard to say too much good about this product.

    This is by far the best FZ-09 upgrade you can buy. The stock throttle tube was manageable but I found myself having to concentrate on my throttle way too much. After installing the throttle tamer throttle response seems much more natural. I don’t have to think about it whatsoever. It improved by parking lot game drastically. With the stock I would have issues in the twisties as well. Instead of giving the curve 100% of my attention I was always worried about that throttle jerking and losing the rear end.

    TLDR: Just buy this thing. There are absolutely no negatives with it.

    Totally takes the jerkiness out of the throttle. Well worth the $$ and effortless to install. Don’t have to concentrate so much on throttle position now and can easily manage the fuel input and keep my attention where it should be, on the road.

    Best add on so far!

    The G2 throttle tube should have come as standard equipment on the Yamaha MT/FZ 09. Makes a great bike the perfect bike.
    No more mid corner jerkiness from the old on/off throttle switch. And no more nearly running in to the back of cars in stop start traffic.
    Has transformed the bike to a tamed beast now and wheelies are way more controllable.

    The throttle tamer is a quality piece. It improved the throttle response of my ’14 FZ-09 but didn’t quite solve the problem. I haven’t had the ECU reflashed by Yamaha with the ’15 FJ-09 map…I suppose that will be the next step after I confirm that it will be compatible with my aftermarket exhaust.

    I had the ECU updated on my 2014 FZ09. Throttle response was improved but still jerky. After installing your Street Tamer Throttle Tube response was again improved, but to a greater degree. I now use the ‘Standard” engine map even around town. High quality, easy to install, works as advertised. Thank you G2!

    When I realized that I couldn’t get enough slack in the throttle cable and return cable by adjusting the barrel adjuster, and would have to work it out at the other end, where it joins at the throttle body, I decided to wait until the next time I had the tank off for other work and ‘kill two birds’. I don’t ride in traffic much, so it isn’t such a crucial issue in my case, but I am looking forward to enjoying the benefits that others have discussed.

    I purchased this tamer to replace the one I had put on my bike back in 2009 (different brand tamer) which got worn out. It feels good so far but since there really is no “taming” my 2009 Vmax I guess time will tell how it holds up.

    Best thing i’ve ever installed on a motorcycle. Got completely rid of the jerkyness of my MT09 (FZ09 in the USA).
    Installation took about 5 minutes, little bit of free-play adjustment was needed. Lovely machined bit of kit. The handling of the bike has totally changed, no more need to overanticipate extreme gasresponse. The motorcycle behaves like it was carburator-fed. Top tranformation with a Top-product

    I bought this for my 2017 Yamaha MT-09. The bike has decent fueling already, but has a sensitive throttle in STD and A mode. I installed this product quickly and easily without any prior experience. After installation the throttle cable needed to be tightened slightly, but after this was done I was extremely impressed with the throttle response. It’s still urgent in STD and A modes, without the rubber band feeling of B mode, but is now noticeably more controllable at slight throttle inputs around town and mid corner. It came with the 400 profile and I was initially worried that it might dull the throttle too much, but thankfully that wasn’t the case. I now leave the bike in STD mode as it is responsive and easily controllable at all speeds. This is a fantastic product with no downsides!

    Put on my 2015 fz09. Road the bike for 5,000 miles stock and I hated the throttle response. Very twitchy and jerky and the bike has far to much power to have that problem.

    The throttle tamer instantly transformed the bike. Makes it feel like a 600cc sport bike in the street as far as the torque goes. Makes riding the canyons a lot more confident too! Even launching from a stop light….just everything got better. I am putting another one on my xr400 supermoto!!!!!!

    Was worried I would need to ditch my FZ-09 due to its, “on/off” throttle issue. Thankfully, the G2 Throttle Tamer eliminated this, and now I can smoothly roll on the throttle, safely. A truly great product that does EXACTLY what it says it does. Thanks G2!

    Fitted to 2015 MT09, remapped with Akro full system. I previously rode in STD and B mode to reduce the snatchy throttle in turns. The tamer changed the initial power delivery in A mode to be totally usable. Such a simple but effective modification. Very well made product that takes approx. 15 mins to fit. Well done G2.
