The VX uses the same bearings as any other Honda engine. Due to the restrictive intake manifold it stops building power at 5500rpm which is probably why the redline is only 6000, but it's 99% part compatible with engines that rev up to almost 8k. You're not going to break anything rev'ing it up to 3k, but you will hurt your economy.

I once destroyed a distributor in a B series motor rev'ing it past 9k (in 5th gear) but it sustained no other injuries.
