- KTM Chain Adjustment
Proper KTM chain adjustment is important if you want your KTM chain, sprockets and more to work properly and last as long as possible.
Not running the proper chain tension can create havoc for your sprockets, chain and even counter shaft seal bearings. An improperly adjusted chain can even cause your sprocket bolts to come loose.
To do KTM Chain Adjustment properly, start with the bike on a center stand with the wheels off the ground. On the inside of the airbox cover, KTM provides a diagram that shows the range in which your chain slack should fall. Typically it is between 55-58mm mm.
You can measure your KTM chain slack with a tape measure or calipers. Measure right behind the chain slider from the swing arm to the chain, with the chain pulled up tight.
If your chain is out of the recommended adjustment range, it’s time to tighten or loosen
KTM Chain Adjustment Steps
First, loosen the axle nut enough to allow the wheel to move. Then, with a 13mm wrench, loosen the lock nut on the axle block adjuster bolt. Use a 10mm wrench to turn the bolt clockwise for more chain slack or counter clockwise for less chain tension. Adjust each side equally and match the markings on the axle blocks to both sides.
When your chain is within the manufacturer’s recommendations, use a shop rag to wedge between the sprocket and the chain. Roll the wheel back until the chain is tight and the wheel is pulled up to the axle block adjuster bolts.
Now, tighten the axle down to proper torque specs. For most KTM’s this is 80 Nm or 59 ft.lbs.
Roll the wheel forward and remove the rag from the sprocket and chain. Lock down the nut on the axle block adjuster bolt using your 13mm wrench while holding the axle block-adjusting bolt with a 10mm wrench.
Ensure the chain is aligned by quickly double-checking where the marks on the axle blocks line up with the swingarm.
That’s it. KTM Chain Adjustment is done. You’re ready to ride!
I looked through a bunch of videos and forums and it was a bunch of different ways and this was the simplest, most accurate, and no wasting time! Definitely coming back here in the future
Glad it helped!
Taught me more in 2 mins that multiple half hour videos!
Now this is a propper video... Not that 30min BS
Looooooooooooool 🤣🤣😂
Excellent- to the point, complete and concise. Thank you!
I found that the 55-58mm spec is optimistically loose. When i lined up the center of the front sprocket, the swingarm pivot point and the center of the rear axle the chain is at its tightest. Then adjusting the chain to have enough slack, reinstall the rear shock and took a measurement i had 51mm slack. This is with 14-51 sprockets
Thank you. Short and sweet. Much appreciated.
I’m like finally, a good video on chain adjustment. I’m like yayyy just look on the inside of the air box… popped it off and I realized I had aftermarket plastics…. L ⚰️
super 👍 short , understandable ... 🙏thanks
for 2017 690 enduro, rear wheel nut is not 27mm.
no shit. the one he’s working on isnt a fat ass enduro
Clear and concise.
My locknuts are stripped pretty bad on my bike. Once I get them off I️ gotta buy new ones :(
Nice. Thank you
My ktm 250 says 7 to 10 mm. Seems tight but that is what it says. I saw 5 to 7 somewhere. But 55mm. Is 2 inches plus. 😢. Also he is doing it on the top which my manual says should be tight. Am I missing something? My lical shop is clueless si wantvto do it myself. How he get it on the stool btw. Seems the vital facir although one youtube vid this dude did it on the ground and hsd no slack 😢. Yiu have to be careful on the Internet 😂.
Ktm's specs for the chain is
55mm 58mm
and all other brands its 3-4 fingers
(25mm 35mm)
I think its really too loose in my opinion and i want to know why i have yo do it this way ?
For some reason, KTMs have always run loose. It's just the way they're designed and built.
It may be due to the PDS suspension as opposed to the linkage.
I have tried 3-4 fingers on my Ktm and have blown up two rear wheel bearings from using this method. I think it’s just best to trust the manufacturer
My manual for 250 3rd gen says 7 to 10mm.
@@laur13my 250 says 7 to 10 mm or 0.28 to 0.39 inches. Shop although clueless have all the bikes this tighr (at least. ) i questioned chain toghtness when i bought it and they said that its meant ti be tight. The manual concurs. Maybe bigger bikes different?
what size torque wrench? 1/4? 3/8? 1/2?
I have a 2018 sx 125. I went out and bought all the tools with the sizes you have stated! They are not correct they are tool small!!
He showed tools for the model he worked on. In the end, he said to refer to your specific owners manual. Be mad at yourself
What size is the rear bolt then. Same thing happened to me
@@theredneckrider7422 i own a 2022 and its 32mm
