    Lookign for a G2 throttle, did they stop making them?

    Hi everyone
    i have searched all over the forum, and have decided to get a g2 throttle tamer.
    I jumped on the G2 website and they don't have the sxv in the drop down menu.
    here is the link to the website.
    https://www.g2ergo.com/store/g2-stre...e-for-aprilia/

    Would one of these work for the sxv?


    thanks for your help

    What tube do you have currently? If you have the newer Aprilia tube, it is almost identical in cam profile to the G2 tamer tube from what I’ve read.

    Here is a pic showing (from top to bottom) the original Aprilia tube, the newer Aprilia tube, the G2 A200 cam and the G2 A400 cam:

    i have the first one, perfect round circle. I also have the yellow button, and i wanted to keep it , i read the g2 tube work with the yellow button.
    All the throttle tubes in the parts list have the same part number.. is that the second one in the picture... ?
    i think i would like the 400 cam, i want it as smooth as possible.
    the 400 cam in the pic looks perfectly round, similar to my stock setup..

    If I remember correctly, the progressive tube can be made to work with the old housing, but some minor modification is needed...

    I fit new type of throttle tube into old cover with yellow button and of course yellow button is not operational anymore. Maybe it can be fixed somehow, I did no check as I have cold start solenoid installed.

    I just replaced the OEM throttle tube with the newer version.. Wow , night and day difference, bike feels so much better now especially when hitting bumps and taking corners. More predictable and easier to ride... I lost the use of the yellow button ,but that doesn't bother me much.

    It feels like a new bike, last week i hit one pot hole and nearly done a wheelie with old tube...
    100% this is a must for early model sxv's

    G2 throttle tube is an aftermarket brand.
    They do not make them anymore. So i purchased the latest throttle tube from aprilia that is similar shape to the G2 throttle tube.

    Yes ... "progressive" that was the word in the oem part list.
    is this not like G2 ? Less way by more gas ?

    The G2 throttle tube is made to fit different "cams" so you can change the way the throttle works...

    You can make it linear, or progressive, or like a race bike 1/4 turn throttle....
