After adding 2" risers and new handlebars my clutch cable is completely maxed out.
I've got it connect but when I turn all the way to the left it really pulls the cable tight and I don't want it to be like that for long.
(The stock cable routing seems good too, so I don't think rerouting it is an option.)

Does anyone know of a roughly 2" longer clutch cable that will work with the 2018 KLX 250?
From all the Google-fu I've done so far I can't can't find any listed cable lengths or other people solving this issue.
I have seen people saying that the KLX 300 clutch cable is about 2" longer, but that was all from forum posts talking about 10 year older bikes and I haven't seen many posts about newer year bikes.

 

I have a 2018 as well, and put a set of ProTaper "Charmical" fat-bars on. Even without risers, I thought the clutch cable and brake hose are too tight. I ordered a 2" longer brake hose and also the KLX 300 clutch cable. I have not had a chance yet to mess with those, but getting close. I am currently in the middle of fitting the HDB handguards. If you don't get a concrete answer before I'm done, I'll post up how it goes.

 

Please do let me know how the KLX 300 cable works out.
I've also sent an email request to the custom cables contact at MotionPro to see what knowledge they have about it, haven't received a response as of yet.

I put on 2" risers and Pro-Taper KX High bars.
I've actually got the brake cable to work out the best, probably cause I really only pushed the bars straight up since I'm a taller build (6'-2") with longer arms.
(The bars basically went 2" straight up from stock.)
The throttle cables are decent after doing a little rerouting around other cables.
Just having a real issue with the clutch cable getting to tight when turning to the left.

 

@Neanderthal Any luck with the KLX 300 clutch cable?

 

Sorry - I'm still fvcking with the handguards. It's been a difficult install for me, but just got word back from HDB and ProTaper about a question I had that was holding me up. Installing handguards is just a mess, I have had more fun pressing grease in shock linkage bearings than jacking with these handguards.

 

No problem. I will be receiving the Acerbix X-Factor Handguards today and from what I've been reading about handguards I'm not looking forward to getting them on either.

I actually just called Motion Pro (super nice and informative guy in the custom cable department) and they informed me that their Motion Pro part # 03-0438 is a +3" version of the stock cable for the newer years of the KLX250s (I think he said 2014s and newer).
The pictures of the cable for sale online don't seem to show the actual cable so I'm hoping what shows up has all the correct protective shields and extra stuff.
I should have the clutch cable in a few days and I will update with the results.

I'll actually give an update w/ pictures of everything I've done around the handlebars because it seems like their is a lot of questions without a lot of answers/info on the newer KLXs.

 

The handguard thing is totally dependent on the bar used. I went with a low-rise, low-sweep model and now paying the price, lol.
