My KTM forks (WP CC forks) have always been suffering from harshness over smaller bumps. After I watched this video my mind was blown how huge effect triple clamps have on front suspension. Is it even possible to make KTM forks really good without changing triple clamps?

I dont think that triple clamp is off of one of todays dirtbikes either. If there was that much stiction i dont think anyone would be running stock clamps.
If it was not round untighten, the forks would not go up in the clamps. There is basically very very little margin and slightest degree of wrong angle it gets stuck.
The Shop
Bottom clamp bolts = 8.9 ft/lb (12Nm)
Top clamp bolts 12.5 ft/lb. (17 Nm)
I have a set of stock cast clamps off an EXC-F and machined black SX-F clamps I put on the bike, I'd be interested to try the test with both of those as well.
The performance trick was to remove the lower set of bolts
Was a little worried the low torque would be an issue and slip but Tevin Tapia raced my bike at Straight Rhythm with that low torque and nothing moved.
