Wholesale Durable CD70 Spoke High Tensile Steel for Wheel Upgrade 250*17 Suppliers, Supplier

CD70 spokes are precision-engineered, model-specific components that connect the CD70 motorcycle’s wheel hub to its rim. They ensure wheel structural integrity, stable rotation, and load distribution, tailored to the CD70’s 17-inch standard wheels and daily commuting needs.

Product Description

Product Overview

Exclusively designed for the classic CG125 motorcycle, these spokes are crafted from high-tensile carbon steel — selected for its balance of strength and lightweight performance, critical for supporting the CG125's ~110–120kg curb weight. Each spoke features a precision-machined M5 thread (for seamless pairing with OEM spoke nipples) and a bent/hooked end (to secure into the CG125's rim spoke holes).

Available in front (135–140mm) and rear (145–150mm) variants — differentiated to match the CG125's distinct hub designs (rear hubs integrate brake drums, requiring longer spokes for alignment) — they come with chrome or zinc plating to resist corrosion from rain and road splashes. As direct OEM-compatible replacements, they eliminate wheel wobble caused by mismatched generic spokes, ensuring consistent performance for the CG125's low-displacement (125cc) urban riding scenarios.

Key Advantages
1. Model-Specific Precision Fit

Tailored to the CG125's hub/rim dimensions (17-inch wheels) and front/rear length differences, ensuring no modification is needed for installation and avoiding rim misalignment.

2. Durable High-Tensile Build

Made from high-tensile carbon steel, they resist stretching, bending, and breakage under daily load and road vibrations, extending service life.

3. Corrosion Resistance

Chrome/zinc plating protects against moisture, road salts, and splashes — ideal for long-term use in urban or mild rural environments.

4. Stable Load Distribution

Optimized for the CG125's weight and riding style, they evenly spread stress across the wheel, preventing individual spoke strain and maintaining wheel roundness.

Applications
1. CG125 Wheel Maintenance

Replaces broken, rusted, or stretched original spokes during routine servicing to restore wheel stability and safety.

2. OEM Replacement for Repairs

Used by repair shops to fix CG125 wheel wobble or spoke failure, ensuring compliance with the motorcycle's original performance standards.

3. Aftermarket Wheel Upgrades

Paired with CG125-compatible 17-inch rims (steel/aluminum) for custom wheel builds, preserving the model's original wheel geometry.

4. Preventive Replacement

Proactively replaces aging (5+ year-old) spokes on high-mileage CG125s to avoid sudden failures during commuting.

Frequently Asked Questions

Are these spokes compatible with all CG125 motorcycles?

Yes, these spokes are specifically engineered to match the hub and 17-inch rim dimensions of classic CG125 motorcycles as direct OEM replacements.

Why are front and rear spokes different in length?

The front spokes are 135–140mm, while the rear spokes are longer (145–150mm). This difference is necessary because the rear hub integrates a brake drum, requiring longer spokes to ensure correct wheel alignment.

What material is used and how durable are these spokes?

They are manufactured from high-tensile carbon steel with a tensile strength of ≥ 1000 MPa, providing excellent resistance against stretching, bending, and breaking under daily loads.

Do they offer rust protection?

Yes. The spokes are finished with chrome or zinc plating, which acts as a protective barrier against moisture, rain, road splashes, and salt corrosion.

What is the average lifespan of these spokes?

The expected service life ranges from 5 to 8 years. For typical urban commuting, they generally provide reliable performance for about 6 years before preventive replacement is recommended.
