NTN offers this engine bearing for SUZUKI LT 125 QUADRUNNER 2WD, LT 230, LT 250 QUADRACER 2WD, LT 250 QUADRUNNER 2WD, LT-F 250 OZARK 2WD, HONDA CRF 230, TRX 250 EX SPORTRAX 2WD, TRX 250 FOURTRAX RECON 4WD, TRX 250 TE FOURTRAX RECON ES 4WD, TRX 250 TM FOURTRAX RECON 4WD and KTM EXC 300, EXC 300 M/O 1983-2018. 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 NTN?

NTN, the Japanese bearing maker founded in 1918, is the brand chosen by engine specialists such as ProX for their crankshaft bearing kits.

When should you replace the bearings?

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.
