The newer ones are improved, and last even longer than the old ones did.
I have the original pawl in my 2000 Bullet, and it gets kickstarted every time, because it's a kickstart-only bike.
If you have the bike tuned well, so that it doesn't do many kick-backs, then it's going to last a long time. But, it's good to have one on hand, just in case it did break. It can happen with a bad kick-back.
But honestly, when I was re-jetting my carb for the exhaust and air-filter change, i got some hellacious kick-backs because it was lean, and my pawl made it through that just fine.
