Zeta and Motion Pro both offer "quick turn" thottle replacements. My factory plastic model is getting a bit worn so, next time I break down the handle bar grips I want to replace it.

I don't really want a 1/4 throttle because it will be too twitchy on the street with a pumper carb. Which aluminum throttle sleeve assembly retains a factory amount of rotation?

THANKS!

 

I put the stock throttle back on after running a 1/4-turn throttle for a while. The 1/4-turn throttle, for me at least, was too twitchy on tight, rocky, technical trails. I really didn't have a problem with it on the street - it was actually fun.

Anyway, when I put the stock throttle back on, I got a Motion Pro replacement throttle tube for a KLX300 and it worked fine. http://www.motionpro.com/motorcycle/partno/01-0080/ This throttle tube retained the stock rotation but had a removeable endcap for handguard mounting (it is plastic, not aluminum). According to Motion Pro, this throttle tube fits a bunch of other bikes too, including almost all Honda XR/XL 250s through 650s. If you search the web for, say, an XR400 throttle tube instead of the KLX250s, you'll likely turn up more results. For example, Fly Racing makes billet throttle tubes for all of the XR/XL's 250+ which will work. http://www.flyracing.com/products/ha...throttle-tubes

Another, more expensive, way to go is to buy a Motion Pro Vortex or Turbo throttle, then buy G2 Throttle Cam System for it. The G2 throttle tubes come with 3 replaceable cams that have different profiles for different types of riding.

 

Sid,

I had both models of Zeta aluminum throttle tubes and they didn't fit the 07 KLX 250s stock housing. Just wan't to give you a heads up.

Still looking to replace my stocker with something better. I don't need a dual setup with the pumper carb either so my options should be better?

Mustang,

Is the 300KLX a single cable setup?

I was thinking about finding a single cable housing off a more popular style and get an aluminum throttle tube to fit it instead of the KLX stocker?

 

I have Pro-Taper bars. Are the aluminum throttle bodies that hard to fit?

 

Hey Guys, Check out MooseRacing. They have a some Al tubes. Didn't see a KLX250,but sounds like you're OK w/ that.? Good Luck

 

this is for you wild will... the klx 300 has the same cable setup as the 250 and i just installed the motion pro vortex and i must say i am very impressed with the results

 

Not hard to fit... just have't found a stock replacement aluminum throttle tube that fits our 07 models? The Zeta fits the 09 model which is different than the 07.

Found this sweet one but vey pricey! http://www.jokermachine.com/itemoffr...&Placeholder=0

I might go with the motionpro turbo and the $60 G2 tube for the turbo instead, I don't really need all the cams that go with the full system.

 

Thanks for the info!

 

I'm happy with the vortex.
It's a bit twitchy off the stop, a bit on/off at really low throttle.
But you get used to it and on the trails I find it a lot better.
