Just what I was looking for

I purchased this to help perk up the lazy throttle response on my Z750S. So far I'm happy with the result.

One of the best things i bought this year

the g2 quick turn throttle tube is amazing for track racing and good for woods riding if you like the full power of your bike. i have it on my 2005 kx250f and it is amazing i go almost twice as fast is some of the places i ride i love it for the vxcs cross-country racing because it allows me to get the power i need to get around in the woods and it only uses about half of the movement of the stock one i had. it has a removable end cap and interchangeable cams to adjust the quickness of the turn but those are sold in a different pack so if you have the money to spend on an $80 throttle tube then go for it but if you want more response out of your bike this is the best way with out breaking the bank and the cams are like $20 a piece so if you want to try one later on you can

A really super quality throttle tube. makes for a short twist of the throttle and helps motor stay in rev zone. Would recommend this for faster individuals.

Just another mouse trap?

The machine work and nylon liners are spot on. Very smooth rotation. I normally don't drop money on parts like this, but with my second plastic tube damaged I thought I'd try it out. Not so sure I agree with the quick turn bit. If its quicker its not by much. I find it has much less resistance there fore a "quicker turn". This product will go on future bikes the same time as the WC clutch perch from now on. Buttery smooth, but they lost a star for the asking price.

Worth the money

I bought the G2 quick turn throttle for my wife to eliminate bent wrist.
It is not too aggressive on the Honda crf250x. My wife has had only one day with it and it does seem to help limit the amount of turn.
I will check this over the next few rides.
The quality is good.

great product over all real nice smooth acceleration the only sucky thing is that you have to oil up the handle bars every once in a while

Good buy for right application

I read a lot about he 'quick turn' throttle and thought it sounded like just what i needed for my 250f. so in the off season i ordered it and installed it. it works really well and definately makes your 250f rev to that sweet spot almost instantly. the only warning i would give you is to really consider the conditions you will be riding in as well as your riding ability. i dont know about all of you but during the winter months i tend to remember myself as a much faster rider when im ordering stuff for the next riding season. this happened to me and resulted in me feeling somewhat uneasy the forst time i hit the track with this throttle tube. you must have an excellent feel for the bike and or the clutch bc you will honestly be riding around the track either pinned or with no gas at all...also, i wouldnt recommend this for trail riding or anything other than a track. I took my bike up to our lake cabin where we typically ride logging roads and explore and stuff and i was constantly 'bimping' the throttle and my tire was breaking loose...this thing is not for trails or anywhere you need consistant throttle controll. I ended up irdering the stock cam and using it for trail riding...overall it is an awesome throttle tube-for the right riser and right track....also i crashed during a race on the throttle side and the removeable end cap came off and was lost...i called G2 and the owner sent me 3 replacements free, so props to them for backing their product. 2010 crf250


Skeptical until first lap. Awesome mod for 250Fs especially. Well spent $50.

Definelty worth the money. I was kinda skeptical at first when I bought this for how much they wanted for it but it is way better than the stock one. Has alot better feel and when you let go of the throttle when it is in the wide open position it snaps right back to closed every time.

Didn't make quite the amount of difference i was expecting, but it definitely did help. Overall, it is a solid product. Had a guy land on me, which bent my bars a good 6 inches, but the throttle tube still works just like the day i got it. Comes with a nice end cap.

Why didn't I get this sooner!!!

After two uses I really feel that this product has help with my riding. It makes it feel like the bike has more power but in reality it doesn't it just brings the power to the wheels much faster. It really helps with acceleration after tight corners, which is exactly what this product advertises. It took a few laps to adjust to the new throttle sensitivity but after that it was awesome!!

Great product

prefect!!!! A1 must have for any kind of motocross dirt bike riding very good product

Spangdahlem, Germany

I had one crash since i put this on my bike and the end broke off. And it was a little 3rd gear double. luckily it's still usable, if you like a shorter throttle. JUNK. but it looks cool.


throttle tube is great fit on my crf250r perfect its buttery smooth does not have to twist quite as much as stock.

Just right

it does just what you would expect. i thought at first i might not like it on the trails but i tried it out last weekend and loved it just as much as i did at the track.

dirtrider38 Top 500 Contributor
Awesome product

This is awesome, This is by far the best up grade I have put on my bike so far , and its not the only one. This could possibly even prevent a crash, helps me alot when im coming up to a jump around a hard corner.

A: The G2 system will change how fast the throttle is twisted with less arm movement. It will NOT change your ignition system on the bike.

Q: Does it come with adjustable cams?
Over 8 years ago
does this one come with different cames like the other guy?
Expert MotoSport Staff
Over 8 years ago Location: Portland, OR
A: This quick turn is different to the Cam system (the other guy). This will only include 1 cam that cuts the throttle turn down to about 1/4 turn.
Over 7 years ago Location: so cal
A: actually, this company does offer different cams and can be purchased separately and easily swapped out for the cam that comes on this particular throttle tube. the wonderful folks here at motosport should be able to special order them if they are able to get these.
