TT250 steering head - heads up

My OE ball bearings were overly snug for that type bearing. The lower outer race is already showing the early signs of dimpling. they were pretty well greased though and still moved smoothly, even when requiring more force to turn than a ball bearing should. I’ll feel better knowing it has tapered rollers and decent seals. The OE lower seal wasn’t installed properly and had a folded and partially torn lip. The upper bearing had only a shield and no seal at all. The stock set up is just adequate but no better.

In your case I agree. If they do fail, definitely upgrade. Your bike sounds like it was assembled on a Friday.
