HOT RODS Transmission Bearing Kits for YAMAHA YFZ 450 2009-2025

HOT RODS offers this transmission bearing kit for YAMAHA YFZ 450 2009-2025. The engine’s shafts run on ball or roller bearings in the cases. They carry heavy loads at high revs and eventually develop play.

What is this bearing made of?

Races and balls (or rollers) in hardened chrome steel, 100Cr6 type: a very hard steel that withstands the fatigue of millions of engine revolutions.

• Open bearing: unsealed, it is lubricated and cooled by the engine oil; clean oil is its best protection.
• C3 / C4 internal clearance: slightly more clearance than normal for a hot engine’s expansion; always refit the original clearance.
• Limit: it dislikes dust and old oil; running short of oil destroys it within minutes.

Why choose HOT RODS?

Hot Rods, the bottom-end specialist since 1993: crankshafts, rods, bearings and seals for a complete rebuild.

When should you replace the bearings on your YAMAHA YFZ 450?

On competition bikes the main bearings are replaced at every bottom-end rebuild, at the hours recommended by the manufacturer. With the cases open, spin each bearing by hand: the slightest rough spot means it must go.
