KX125 Clutch Actuator

Post by ericr »

I've searched the forums and have found mention that people have replaced their clutch actuator with one from a KX125 for lighter clutch pull. Supposedly, the arm is longer and gives more leverage.

Has anyone actually done this and knows the part number?

I ordered one and it does not fit. The shaft is too short.

I'm finding different part numbers for this item;

Rocky Mountain - 13236-1259, cross references with KLX's of various years.
Partzilla - 13236-1195, cross references with 89-91 KDX200.
ebay - Most listings for 1989 KX125 shows it fitting the KLX's.

I bought one off ebay for a 1989 KX125 that cross referenced to the KLX's and it did not fit. Does anyone know for sure what the correct part number is and cross reference? Thanks!

I've not heard of this particular mod, but doubt it will be easy to find a drop in replacement. The clutch pull on a KDX is already pretty light.

There's been a couple posts on this where people have done it and have claimed clutch pull lighter than bikes with OEM hydraulics. Unfortunately, they didn't leave details.

Even new, a KX125 actuator is about $25 - way less than a Magura hydraulic at $300. If someone has done it, and has a part number, I'll spend $25, or less, to have an effortless one-finger clutch.

I put one on. Great mod. I don't remember what year I purchased and I can't see that far back on my purchase history. I know it was pretty much a straight swap.

Did a little research, since the H series bike really spawned from the 92-94 KX125 a quick look at the 93 KX125 clutch actuator (13236-1230) may work. THey share the same needle bearing so the shaft diameter is the same, and appear to have the same length, though can't find any info on the length of the arm. Also they don't appear to be readily available at several parts houses, but maybe it gives you a starting point?

Do you recall if it was at least a 1989 KX125 actuator? That might narrow it down to the other part number.

Good detective work. If we can get someone to verify that they used an actuator from that year range, we have a part number. Thanks.

I think Buffsteter is right. I think the 93 is the year that I used. I got mine on eBay for cheap. That way if it didn't fit, I wasn't out a bunch of money.

Ok, I'm going to watch ebay for a 92-94 actuator. We'll see if it works. I just realized that we had 3 members from WA discussing this. I'm going to Walker tomorrow for the first time in 20 years. Back then, it seriously kicked my ass. I have a better bike now so it should be ok, right?

lol...Rode the Kilted Duck poker run last weekend up there, lots of good trails, some technical stuff that can get quite ugly in the wet. First time I had ridden there, the impression I got was that not a lot of trail maintenance gets done and they ride it year round so it does get pretty chewed up. Still was a lot of fun! And burgers afterwards at the Conway Pub and Eatery make the drive worthwhile!

As an alternative, you can also add an extra 1/4" to 1/2" to your current KDX200 actuator arm to reduce lever effort...
This method is also mentioned here on the forum somewhere (I think 1/2" was mentioned as a maximum) - I've been meaning to try it but haven't got to it yet.

Yamaha 450 owners use this easy mod to decrease lever pull effort, I’ve seen it done and it does work

Am I the only one who thinks if the clutch is too hard to pull you just need to hit it with your purse?

Yeah, if it's hard to pull something is wrong with it or the operator!

Yes, there is something wrong with the operator. It's called aging, and it sucks. For me, it's given me arthritis in my hands which forces me to use two fingers on my clutch. Despite that, many of us old-guys are still out there hitting the trails. If I can add a cheap mod that will help me keep at it into the future, I'll do it. It's either that, or I should start shopping for a new wardrobe accessory, eh? :yawinkle:

Maybe I'm still too young at 49 to notice how stiff it is! The only issue I have with the clutch pull is not being able to adjust the reach of it for my short sausages!
