thumb throttle on dbike

[bens250ex]

i recently got a dirtbike and would like to try using a thumb throttle on it. its a 02 kx250, anybody know what thumb throttle set up would work for the swap?

[slightlybent47]

Don’t do it man!!!!! You’ll wind up on your ***!!!!!

i have a hand deformation so i need to try it..it can be reversed back to twist if it doesn't work for me so its worth a try.

i used a reg honda 450r throttle and cable , works great i love it ! mine was a kx250f tho

[deathman53]

250r throttle and motion pro cable for a 38 a/s or 39 pwk carb

Ok then if that’s the case then give it a try you may like it. but there is a reason why bikes have a twisty and not a thumb. I tried it once and I spent more time on the ground then I did on the bike.lol

I did it on my yz250f with a terry cable throttle assembly and yfz450 cable

then just removed the push cable and plugged the hole in the carb.

It worked good.. but was just a short term solution so i could ride with a cast, alot faster on the twist once you get used to it

I put a Honda throttle on my Kawi. Took like 10 minutes and works perfect

i dont get why you would crash more with a thumb throttle. i tried riding my crf with the twist and hated it, went the thumb throttle and no problems since. if you can get used to the twist then i would keep it but it just didnt feel right after using thumb throttles forever

[bens250ex]

i have used twist throttles alot and i am comfortable on them with normal riding, but on the track it is different story so hopefully the thumb throttle will help me be able to improve track wise. thanks for all the input when i get it together i will let ya'll know how it feels

Twists are better on trails, but on the track, I cant live without a thumb. You'll like it. It acctually helped me add a lot of control in the air, I dunno why though haa

yeah i can ride my yz through the trails fine but i cant get used to hitting bumps and holdin my arm still i will be sticking my yfz throttle on my bike and getting a 400ex throttle for my yfz

The biggest problem I had with the thumb throttle on the two wheeler is if I was close to the tank and turning a right hand corner. I would hit the throttle with my leg and I may or may not have a grip on the clutch and end up on my ***. And any time I was up on the tank I found it harder to get on the throttle. I also found it hard to stay smooth in ruts with the thumb throttle. May be it’s just me but I didn’t like it. But hay if you have a hand problem and a thumb throttle will help you then that’s the way to go, it may work better for you, and if that keeps you riding that’s all that counts. Ride with caution till you get use to it and watch out for the things I mentioned.Good luck with it.

is a 400ex thumb throttle the same as a 250r?

[99_300ex]

Ya I think pretty much all Honda's thumb throttles are the same

i run a 400ex throttle with trx450r cable on all my dirtbikes...works great! dont listen to anyone saying it wont work..if you like thumb, do what you are comfortable with.. you will learn to ride the bike even faster!

Exactly. I gained at least 10 seconds a lap with a thumb, and that is not a guess, my dad timed me. Granted, I am pretty slow on a bike haha. I know for a fact that a Trx450r throttle and cable works for the conversion with no modding.

Is it possible to but a thumb throttle off of a 450r on a fuel injected bike?

[atveric132]

so same setup should work on an 08???

[BlaineKaiser450]

It should, I dont see why not

[eastside 400]

the honda throttle and cable should work on all newer 4 stroke bikes, the cable will most likely not work on a 2 stroke due to the carb being different, but all modern 4 strokes use the FCR carb

[ridehonda400ex]

I wouldnt use nothing but a twist throttle. I bought my quad with one and will never switch back. I feel like i have more control with all my fingers on the bars and i feel much faster with it. But that is my opinion

still a bit confused on which will work.. will a 400ex throttle work with the cable for the 38/39?

How do you like the power on the kx250f? I've been throwing around the idea of getting a bike.

I can wheelie out of any corner I want depending on where I sit. Its awesome. I would definatly reccomend a Kawi like mine. It's really easy to work on, has great power and suspension, and overall, its just a blast to ride!
