Engine Crankshaft Bearing – Hyosung GD250R GD250N
Banish deep engine knocking and hazardous crankshaft deflection. These high-tolerance crankshaft main bearings act as your essential mechanical insurance during a single-cylinder bottom-end rebuild, ensuring you don’t get left stuck in the garage with a locked engine casing or a dangerous bodge fix from untrusted sources. Engineered to manage the continuous load limits of high-compression thumpers, they restore balanced rotational stability while preserving your cases from immediate, severe damage.

Description
The liquid-cooled GD250 engine is a high-revving, high-compression single-cylinder thumper, making reliable crank bearings absolutely essential to its function. After thousands of aggressive miles on the road, noisy or rough running bearings indicate critical mechanical wear is occurring inside the oil pools. Replacing them during an extensive engine overhaul is crucial. We source superior, load-matched components designed to resist severe wear and tear, satisfying your build needs with performance that lasts. This listing provides a pair of bearings (left & right). If your specific engine configuration calls for a set of four internals, simply modify your checkout quantity to two sets.
💎 Precision Parts for Longevity
Material quality matters far more than a cheap price point when rebuilding the core of your motor. Ensure your GD250 single-cylinder lower-end remains perfectly tight and oil-sealed on the first pass.
| High Durability Hardened steel alloy assembly engineered to withstand sustained track-level RPM demands. |
Reduced Friction Precision ground parallel tracks minimize drag coefficient for smooth, balanced power delivery. |
| Engine Overhaul Essential Eliminates persistent low-frequency thumper knocking and internal casing roughness. |
OEM Spec Fit Dimensionally stable footprint guaranteed to seat perfectly inside the crank journal hangers. |
📜 Confirmed Fitment Guide
📅 YEARS: Covers all model production years spanning 2013 through to 2020.
Don’t skimp on matching seals! Block messy casing leaks from ruining your hard work by securing a fresh **Engine Gasket Kit** to ensure every joint face is perfectly dry during your lower-end overhaul.
🔧 Install Tips
- Professional Fitment: This is a high-level specialist project. Crude hammer force or misaligned press steps can instantly warp the outer track or damage the main crank teeth, leading to immediate engine seizure. Consult a service manual or professional engine mechanic.
- Service Manual: Assembly instructions are strictly intended for experienced mechanics. You must follow the official factory service manual closely for precise center-case mating layouts and lateral torque settings.
