Wholesale Durable CD70 Spoke High Tensile Steel for Wheel Upgrade 250*19 Supplier, Exporter

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 19-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

What materials are these spokes made of?

They are crafted from high-tensile carbon steel, offering a balanced combination of high strength and lightweight performance. They also feature chrome or zinc plating to provide excellent corrosion resistance.

Why are the front and rear spokes different lengths?

The front and rear spokes are sized differently to match the CG125's unique hub structures. The rear hub integrates a brake drum which demands longer spokes (145–150mm) for proper wheel alignment compared to the front spokes (135–140mm).

What size rims do these spokes fit?

These spokes are fully compatible with standard CG125 17-inch steel or aluminum rims configured with a 36-spoke hole design.

Can these spokes prevent my motorcycle wheel from wobbling?

Yes. Because they are engineered specifically to match the OEM geometry and hub sizes of the CG125, they ensure even tension and load distribution, eliminating wheel wobble caused by generic, ill-fitting spokes.

What is the average lifespan of these motorcycle spokes?

Under normal operating environments, these spokes have a service life of 5 to 8 years. For standard urban commuting, the average expected service life is approximately 6 years.
