Description
Crankshaft bearings are the heart of your engine. After thousands of miles on the road, excessive mileage causes noise, roughness, and eventual catastrophic failure. Replacing them during a full engine overhaul ensures longevity and precise engine timing. We source only high-durability bearings, justifying their premium price with material quality designed to last the life of your Hyosung. If you require four bearings (for certain configurations), simply add two sets to your basket.

📜 Confirmed Fitment Guide
📅 YEARS: Generally covers 2001–2021 depending on the specific model variant.
❌ WILL NOT FIT: 650cc V-Twins, GD250 models, or 2019+ EFI “S” models (GV125S).
Since your engine is open, consider replacing the **Cam Chain** simultaneously to maximize engine lifespan and prevent timing issues down the road.
🔧 Install Tips
- Professional Fitment: Incorrect installation can damage the crank teeth or seize the engine immediately. We strongly recommend a qualified mechanic handles this job.
- Use Service Manual: Always refer to the official Hyosung service manual for correct torque settings and installation procedures.
- Buy a Full Set: For even wear, always replace both the left and right side bearings at the same time.
