A GN125 bike chain is an important component of a GN125 motorcycle. The GN125 chain comes in different types, and each type has its own set of features and specifications. Here are some popular types of GN125 chains:
Roller Chains:
GN125 roller chains are also called drive chains. This type of chain features a cylindrical roller link that is used to lift and pull. GN125 roller chains are popular in motorcycles because they have high tensile strength and low wear resistance. Generally, GN125 roller chains are suitable for heavy-duty applications and high-speed operations.
O-ring Chains:
O-ring chains are called so because of the two rubber O-rings between the inner and outer links. The O-rings serve as seals that keep the lubricant in and also prevent dirt and debris from entering the chain. This feature gives the O-ring chain a longer lifespan. O-ring chains are also low-friction chains, as they reduce power loss during transmission. Due to their durability and low maintenance, O-ring chains are widely used in motorcycles.
X-ring Chains:
The GN125 X-ring chain is similar to the O-ring chain. However, the X-ring chain features an X-shaped ring. The X-shaped ring offers better sealing and less friction than the O-ring chain. Like the O-ring chains, X-ring chains also have long service life and low maintenance features. Generally, X-ring chains are suitable for high-performance motorcycles.
Sealed Chains:
GN125 sealed chains are chains with a removable link. This type of chain is easy to disassemble and reassemble. GN125 sealed chains are commonly used in motorcycles because they are suitable for low-speed and light-duty applications.
Heavy-duty Chains:
GN125 Heavy-duty chains are also called high-strength chains. This type of chain is designed for heavy-duty applications. The GN125 heavy-duty chain has high tensile strength and can withstand high loads. Generally, heavy-duty chains are suitable for industrial applications.
The specification of GN125 chain varies depending on the type, but here are some general specifications:
Size
The size of the GN125 chain is based on the measurement of the inner and outer plates. The most common sizes are 428 and 520. The 428 size has a pitch of 1/2 inches and a width of 1/4 inches. The 520 size has a pitch of 5/8 inches and a width of 1/4 inches.
Link Count
The link count of the GN125 chain ranges from 102 to 120 links. The number of links is based on the length of the chain.
Material
The material of the GN125 chain is made of high-strength steel. This steel is designed for durability and wear resistance.
Type
There are different types of GN125 chains, such as roller chains, O-ring chains, and X-ring chains. Roller chains are the most commonly used chains in motorcycles. O-ring and X-ring chains offer better durability and wear resistance.
Load Capacity
The load capacity of the GN125 chain is measured in tensile strength. Tensile strength is the maximum amount of force that can be applied to the chain before it breaks. Tensile strength ranges from 8000 to 12000 N (Newtons).
Pitch
GN125 chains have different pitches, which is the distance between the pins. The pitch is measured in inches or millimeters. The most common pitches are 1/2 inches or 12.7 mm.
Roller Diameter
The roller diameter is the measurement of the roller on the chain. The roller diameter is important because it affects the wear of the chain. The most common roller diameters are 0.312 inches (7.9 mm) or 0.375 inches (9.5 mm).
Width
The width of the GN125 chain is measured between the inner and outer plates. The width is important because it affects the fit of the chain on the sprockets. The most common widths are 0.125 inches (3.2 mm) or 0.16 inches (4.0 mm).
Maintaining the GN125 chain is an important aspect of the maintenance of motorcycle parts and accessories. This is because a well-maintained chain improves durability and ensures the smooth operation of the motorcycle. Here are some maintenance tips:
Regular Inspection
Inspect the chain regularly for signs of wear, damage, or elongation. Check for loose or missing links, as well as any rust or corrosion. Inspect the chain for proper tension and alignment.
Cleaning
Clean the chain regularly to remove dirt, dust, and grime. Use a chain cleaner or kerosene and a soft brush. After cleaning, rinse thoroughly with water and allow the chain to dry completely before applying lubricant.
Lubrication
Lubricate the chain with a high-quality chain lubricant. The lubricant reduces friction and wear between the chain and sprockets. Ensure even distribution of the lubricant by applying it while rotating the rear wheel.
Tensioning
Adjust the chain tension as needed. A loose chain can cause slippage or damage, while an overtightened chain can lead to premature wear. Follow the manufacturer's recommended tension specifications.
Replacement
Replace the chain if it shows signs of significant wear, damage, or elongation. A worn or damaged chain can lead to poor performance and increase the risk of chain failure.
Sprocket Inspection
Inspect the sprockets for wear or damage. Replace the sprockets if they are worn or damaged. It is recommended to replace the sprockets simultaneously with the chain.
Chain Guide Inspection
Inspect the chain guide for wear or damage. Replace the chain guide if worn or damaged.
Check Chain Alignment
Check the alignment of the chain and sprockets. A misaligned chain can cause uneven wear and reduce the chain's lifespan. Adjust the chain alignment as needed.
Storage
If the motorcycle is not in use for an extended period, store the chain properly. Clean and lubricate the chain before storage. Keep the motorcycle in a dry, clean environment to prevent rust and corrosion.
Professional Inspection
If unsure about any aspect of chain maintenance, consult a professional mechanic for inspection and maintenance services.
Choosing the right GN125 chain for a business can be a complex task. Here are some factors to consider:
Understand the GN125 model
Identifying the specific model of GN125 motorcycles in use is the first step. This is important because different models may have slight variations in their specifications. For instance, the GN125 is a general term for 125cc motorcycles. In different countries, the specific brand and model may vary. So, first, find out what brand and model the motorcycle is.

Steps to replace the chain
Q1: How do I know if an GN125 chain is compatible with my motorcycle?
A1: Compatibility is usually indicated on the chain packaging or in the user manual. The chain's pitch and width should match the specifications of the sprockets and the owner's motorcycle manual.
Q2: Can I use a GN125 chain on other motorcycle models?
A2: The GN125 chain can be used on other motorcycle models as long as the other motorcycle's specifications match the GN125's sprocket dimensions. Always verify compatibility before installation.
Q3: What is the expected lifespan of a GN125 chain?
A3: The lifespan of a GN125 chain depends on various factors, such as maintenance, riding conditions, and load. A well-maintained chain can last anywhere from 15,000 to 30,000 kilometers, but this is just an estimate.
Q4: What should I do with an old GN125 chain?
A4: Do not just throw away old chains, as they can be recycled. Contact local recycling centers or dealers, who can provide guidance on proper disposal and recycling options.
