kx 125 trans oil

8 posts in this topic

I do understand there is alot diff ideas on this but i just need simple advise. My son has a 03 kx 125. I have been using yah. 20-50 2stroke trans oil with no prob. I was in a friends yah shop last week and needed some new oil and he gave me Honda 's HP 80-85w 2-stroke trans fluid. I wasn't thinking and got it. I opened it up yesterday and noticed it was red and stoped. I don't want to put this in and have probs and have to clean the clutches, sugestions please?

That is fine to use in your KX and most likely will give him better clutch feel than 20W50. Also, ATF type "F" works great (Use it in my KX250)in 2 stroke trannies and is very inexpensive. Change often is the most important thing. Many trans fluids are dyed red.

It is rumored that this is really just repackaged ATF, which does explain the red color. IDK if anyone has ever had it tested to see if that is true though.

But the main question is, is this a better oil than what i have been using and is it safe to use in his bike? We have a big weekend of riding and i just don't want to mess anything up.

I'm not real sure of that exact oil. But save yourself some money, take it back and swing by the auto parts store and pick up 3 qts of Type F for the same price as the one factory stuff. At least we know this oil is proven and works. Do a search and you'll see.

As stated above.......yes.......totally safe and I think you'll find the clutch will not drag as much as using 20W50 motor oil. Also as stated above....save some money and go get Walmart or any type F ATF.

With that said, ATF has all the right components to work in a wet clutch/fricton environment. Many people use it successfully.

I think the most important thing is to change it regularly.
