Absolutely mate. But the thing that makes most steering head brgs fuck out early is lack of grease and water/dirt contamination. A lot of the time dirt bike ones will last longer as they often have better seals to keep all the shit out compared to road bikes.Originally Posted by bogan
Shock loads are bad for bearings though, not explode after one hit bad, but I'd expect em to last longer in my bike than Dougs

They should buy a shaft driven bike.
You can't wheelie them!

They also often repack bearings as a regular piece of maintenance. IIRC my DR service guide includes re packing the top and checking the bottom bearing for notches every second service. Checking for notches top and bottom on the other service. My road bike manuals don't even list them.

Headstock bearings are hugely over-spec'd, mostly because the shaft and housing need to be structurally heavier than the bearing that happens to fit that space.Doug told me so

Never mind landing a common wheelie, what height does an MX bike have to land from to generate G forces equivalent to those bearing load limits?
Hint: I'm not volunteering.
Go soothingly on the grease mud, as there lurks the skid demon

I can't read your link from my iPhone but I would suggest we are back in the age of evil kin evil jumping sportsters for distance?

Fuck all actually.Falling 50 metres at 9.8 m/s/s he's doing well over 100kph (vertical) on impact, but he cheated, the shape of the ground spread that impact out over several seconds.
Impressive control in the air though, I have enough trouble keeping the wheels pointing at the ground ON the ground.

You can wheelie just about anything with enough motivation, a little mechanical insensitivity and in some cases modification.
The question is how motivated, rough and inventive are you prepared to be?

Yeah fuck doing that for a joke!Fuck all actually.

Reasonably most of the time.

That reminds me of being told I couldn't put a wood screw in with a hammer. I think they meant shouldn't.
