Do the math! A bike wheel bearing rotates at 7-8% of it's design maximum and runs at a temp of 200C under its max design temp. The operating rotational speed and temp are not an issue.

This is why you can grease-pack bike wheel bearings at 90-95% of void. Keeping moisture and dust out is what saves bike wheel bearings (and a decent axial load spec!!!!)
Never really thought about it that way but take your point. A lot I have seen have had C3 rating on them from the factory. Mostly the old bikes though. Cheers

My apologies to silverfox my response to his post was rude.
I've been under some pressure at work lately and been stressed. When I get stressed I become abrupt and intolerant.

Take little notice of OEM bearing brands SF, they use whatever axial-load bearings they can get cheap. Especially KTM, I've seen Katos with Russian wheel bearings...

That's disappointing, given you pay a premium for the brand based in part on reputation for quality components.
Not meant to be a KTM bashing, as you stated, they all do it.
