Frequently Asked Questions

Q: Why should I buy a complete assembly instead of rebuilding my old crank?
A: A complete Hot Rods assembly saves hours of labor and ensures that the balance and truing are factory-perfect. It eliminates the risk of human error in the truing process, which is critical for 450cc engines.

Q: Is this crankshaft balanced to OEM specs?
A: Yes, every Hot Rods assembly is factory-trued and balanced to meet or exceed the original manufacturer's specifications for your YZ450F.

Expert Pro-Tip: When installing a new crankshaft, always replace your main bearings and seals as a set. Never reuse old main bearings on a new crank assembly, as the wear patterns won't match and will drastically reduce the service life of your new bottom end.
