Crankshaft Bearing – Hyosung GT125 GV125 GT250 GV250 RT125 RX125

Description

Crankshaft bearings are the absolute structural heart of your bottom-end engine. After thousands of demanding miles on the road, persistent high-speed operation causes microscopic rolling wear, leading to loud engine noise, rough running, and eventual catastrophic crankcase destruction. Replacing them during a full case-splitting project ensures absolute long-term durability and completely precise engine timing alignment. We source only high-durability, load-rated bearing sets, satisfying your build needs with material quality designed to survive the remaining life of your bike. If your specific engine configuration calls for a set of four internals, simply modify your checkout quantity to two sets.

💎 Precision Parts for Longevity

When dealing with vital inner crankshaft components, material engineering matters far more than a cheap price point. Ensure your lower-end rebuild remains tight and oil-sealed on the first pass.

📜 Confirmed Fitment Guide

🔧 Install Tips

• Professional Fitment: Incorrect alignment or crude hammer force during press-fitting can instantly warp the outer track or damage the main crank teeth, leading to immediate engine seizure. We strongly advise having an experienced engine mechanic handle the machine press work.
• Use Service Manual: Always follow the official original service manual instructions for precise center-case mating layouts and lateral alignment clearance checking steps.
• Buy a Full Set: To preserve symmetric engine balance and completely even bearing track wear, always replace both the left and right side main shaft journals simultaneously.
