Upper a-arm bearing KIT for KFX450R 2008 PIVOT WORKS for KAWASAKI KFX 450, KFX 700 2004-2014

PIVOT WORKS offers this engine bearing for KAWASAKI KFX 450, KFX 700 2004-2014. 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 PIVOT WORKS?

Pivot Works kits, sold by the American All Balls Racing group, use hardened NTN, NSK or Koyo bearings from original-equipment bearing suppliers, supplied pre-greased with their seals; every kit carries the Pivot Works limited lifetime warranty.

When should you replace the bearings on your KAWASAKI KFX 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.
