    Well,,

    My twist throttle took a dump and is broke.

    I was thinking instead of ordering a new throttle, what is the consensus on installing an ATV type thumb throttle?

    I am thinking that when I build up the New one, I will have front and back brakes, and a clutch lever. It maybe easier to work a thumb throttle.

    anybody done this? what do you think?

    THANKS

    A few people here have done that; some like it, some don't.
    I grew up riding motorcycles, so I prefer to keep all the controls the same as on a MC...

    Niagra sells a sweet little thumb shifter that works with most premade throttle cables for about $5. After you get used to it you dont even think about it being different at all. I have that on one bike and the twisty on the other and like them both. The thumb lever throttle came with my DE kit and Ive stayed with it after getting used to it.

    i bought a cheap pit bike thumb throttle and never used it. i was gonna put it on one of my bikes but it kinda interferes with the brake levers i use.

    I used to have a finger throttle but it cramped my hand, I now use a twist throttle, hand doesn't cramp it just goes numb. The thumb unit may work better than what I was using.

    i remember glamis sand dunes when they were smooth and all of it was open. they had dune cycles, 5 hp fiberglass tubs with 3 wheels and then honda came out with the atc 90 and they had thumb throttles and i had my first thumb cramp. and they will sneak up on you just like that. alot of people switched to twist because once you start thumb cramping it aint going away anytime soon. [twist it around and use your fingers] only lots of riding will cure it

    I use to have an old skidoo with a thumb throttle, and I liked it. The build I am working on will have a thumb throttle because my twist got wrecked last year when I dumped my bike. The reason ATV and snowmachines have thumbs is that in a panic or loss of control the thumb is less likely to accelerate, where as a twist or even a brake lever type throttle you may be more inclined to grip and accelerate when out of control or "startled".

    This was probably covered in some of the links Dave provided but to anyone planning on installing and using any type of throttle control make sure it has a spring return to idle. I've read where some guys have used click shifters which gave them "cruise control". That is a very bad, unsafe idea. In a panic situation you'll want that engine to slow down 'right now', not after you have to fiddle with some kind of mechanical release or detent.

    ferball you are correct i saw a lot of crashes with twist throttles and a click throttle's only good on a lawnmower

    My friend's thumb throttle broke, so I gave him mine.

    I just didn't wanna spend $$ on another. Since both brake cables hook up to a dual-pull lever, I simply reinstalled the bike's original brake lever. Then I connected the throttle cable to the left-side brake lever.

    It works well!dance1
