2016-2021 TC125 / 125SX TWO STROKE TOP END REBUILD

This top end rebuild video should be good for most two stroke motorcycles. This is on my 2020 Husqvarna tc125 and it has the same motor as a ktm 125sx so it should all be the same thing. If you liked this video make sure to give it a big thumbs up and make sure to subscribe!!! Thank you!

Great video! I was looking for a late model KTM/Husky 125 top-end rebuild. There seem to be very few for some reason.

Hi mate what torque specs did you use for the head bolts and cylinder nuts ?

[@16thboyz]

I need it plz

[@tristan6082]

When you ordered that vertex piston where did you get it from and which one? On the motosport website it shows a bunch of different ones. A and b pistons stock bore and then pro race ones. I’d like the one with 2 rings like you have but not sure which one. Is that a pro race piston or the stock bore one?

[@lamortaise4458]

You didn’t check the deck height ?

[@alextrout2631]

Nope

[@jeffwendorf170]

Curious if you did cylinder and piston measurements n bore honing

[@alextrout2631]

Nope non of that

[@andyfinney_at_large]

hey man did you torque the engine bolts to spec? or just tight enough by hand?

[@ichihusni5014]

Hi mate, any idea of exhaust and transfer port duration?
