- KTM 50 SX Top End Rebuild - New Piston Kit
This is 2016 KTM 50 SXS. Piston was shot and all burnt up so it was time to replace it. I used a Vertex piston kit ($100) and it came with all the parts needed to do a complete top end rebuild.

KTM 50 SX Top End Rebuild - New Piston Kit - Навчання та стиль
Wow, what a sharp bike! Your son is seriously lucky!
Thanks
Great video… thanks
🏍🏍🏍 sick bike
It rips!
Remember next time to ensure the open end of the circlip is positioned at 12 or 6 o'clock ;)
Why?
Great video! I just put a new vertex top end in my sons 05 50sx but now has no compression any tips?
Did You ever figure it out bro? Please help I have the same exact problem with my ktm 50 pro senior 2005.
awesome vid. What clutch cover is that ?
The clutch cover came stock from the special edition 50 SX in the 2016 year. It was called an SXS. Which is the dirt bike in the video above. Again, it was a special edition 50 SX model that KTM made for the 2016 model. Kinda like their factory editions they make today. Thanks for watching! Appreciate the like 👍!
How do you measure squash . I presume that what someone said above
Youll need a measuring tape, or sag tool, but the rider sag should be at 80mm.
Does the piston ring have a mark on it ?the instructions say letter side up but I cant find one on this ring.
Never mind seen one of the other post. Aswerd my question. Great video tho thank you.
New to these bikes.... After the instal, is there a heat cycle/time for it to "break in"? Thank you for the video!
just warm it before you go wide open.
Bro I need help man I tore down the top end twice everything is installed correctly. I have a 39.5 piston in a 2005 pro senior ktm 50 and the kick has zero compression.
You have to double check everything... make sure your piston ring has no gap or slit that would allow air to pass through, the wall... when installing your your cylinder head make sure your gasket did not have any tears or small rips... everything has to be sealed tight... hope that helps.
Do you have to worry about deck height or timing with the 50's ?
No, its just a drop in replacement and good to go
Yes you do
How long and what’s the price for the kit. I was thinking about upgrading to a KTM for my 5 year old that is out grown his Honda 50.
Should be under $100... I bought mine off eBay, I paid $90 at the time.... it took me about 2.5 hrs to do it, I change the pistons after about 30hrs on them, but change it as needed.
Do have a big bore for ktm50cc??
No, stock size
Does the piston ring have to go on a certain position on the ktm50?
Yes there a specific grove it sets in... in the video I mention that as im putting the ring on the piston. Also the arrow on the piston needs to be on the exhaust pipe outlet side.
@@TheRealSkeptyk thanks for the reply. I'm talking about the ring specifically though, is it possible to fit it upside down? I know some rings have markings but I don't remember seeing anything about this in the video?
@@motoxcarter2143 i got you, sorry for the misinterpretation... the ring has no up or down side fitment, it is machine cut same way on both top and bottom, basically its universal up or down fitment.
@@TheRealSkeptyk thank you! That's what I thought but couldn't find any information about the rings anywhere!
How to you take the spark plug mys stuck
elbow grease😃
You didn't do deck height ? Wow
lol.....................................
how long do you have it run it in for?
20 to 30 actual ride hours my friend, then change it for a new one again.
@@TheRealSkeptyk i mean when you fit new piston do you have to take it steady for a few hours to run it in?
@@seanmcgrath9167 no break in period, soon as you replace it, you're good to go ripping again
wheelie it`
i'd bust my sh@t.😂
