last longer than titanium. little heavier so lose a bit of performance, but its miniscule enough I doubt you feel any difference. Not having to check valve clearances near as often because you arent beating the seats is a far better trade off than that power loss.

I had to rebuild my YZ250X and pro-x has always been a go-to for me. It's basically equivalent to OEM but a lot of times it's cheaper. Perfect fitment and longevity.

Reliable; at or above OEM quality. Has never gone wrong and is always my first choice for all my bikes when doing a crank.
