How to look at the motorcycle chain model

Question 1: How do you know what model the motorcycle chain gear is? If it is a large transmission chain and large sprocket for motorcycles, there are only two common ones, 420 and 428. 420 is generally used in older models with small displacements and smaller bodies, such as the early 70s, 90s and some older models. Most of the current motorcycles use 428 chains, such as most straddle bikes and newer curved beam bikes, etc. The 428 chain is obviously thicker and wider than the 420 one. On the chain and sprocket , usually marked with 420 or 428, and other XXT (where XX is a number) represents the number of teeth of the sprocket.
Question 2: How do you tell the model of a motorcycle chain? The length is generally 420 for curved beam bikes, 428 for 125 type, and the chain should be numbered. You can count the number of sections by yourself. When you buy it, just mention the brand of the car. Model number, everyone who sells this knows it.
Question 3: What are the common motorcycle chain models? 415 415H 420 420H 428 428H 520 520H 525 530 530H 630

There are also oil-sealed chains, probably the above models, and external drive chains.
Question 4: Motorcycle chain model 428H Best answer Generally, motorcycle chain models are composed of two parts, separated by “-” in the middle. Part One: Model Number: Three-digit *** number, the larger the number, the larger the chain size. Each model of chain is divided into two types: ordinary type and thickened type. The thickened type has the letter “H” added after the model number. 428H is the thickened type. The specific information of the chain represented by this model is: pitch: 12.70mm; roller diameter: 8.51mm pin diameter: 4.45mm; inner section width: 7.75mm pin length: 21.80mm; Chain plate height: 11.80mm Chain plate thickness: 2.00mm; Tensile strength: 20.60kN Average tensile strength: 23.5kN; Weight per meter: 0.79kg. Part 2: Number of sections: It consists of three *** numbers. The larger the number, the more links the entire chain contains, that is, the longer the chain. Chains with each number of sections are divided into two types: ordinary type and light type. The light type has the letter “L” added after the number of sections. 116L means that the entire chain is composed of 116 light chain links.

Question 5: How to judge the tightness of a motorcycle chain? Take Jingjian’s GS125 motorcycle as an example:
Chain sag standard: Use a screwdriver to push the chain vertically upward (about 20 Newtons) at the lowest part of the chain. After applying force, the relative displacement should be 15-25 mm.
Question 6: What does the motorcycle chain model 428H-116L mean? Generally, the motorcycle chain model consists of two parts, separated by “-” in the middle.
Part One: Model:
Three-digit *** number, the larger the number, the larger the chain size.
Each model of chain is divided into two types: ordinary type and thickened type. The thickened type has the letter “H” added after the model number.
428H is the thickened type. The specific information of the chain represented by this model is:
Pitch: 12.70mm; Roller diameter: 8.51mm
Pin diameter: 4.45mm; Inner section width: 7.75mm
Pin length: 21.80mm; Inner link plate height: 11.80mm
Chain plate thickness: 2.00mm; Tensile strength: 20.60kN
Average tensile strength: 23.5kN; Weight per meter: 0.79kg.

Part 2: Number of sections:
It consists of three *** numbers. The larger the number, the more links the entire chain contains, that is, the longer the chain.
Chains with each number of sections are divided into two types: ordinary type and light type. The light type has the letter “L” added after the number of sections.
116L means that the entire chain is composed of 116 light chain links.
Question 7: What is the difference between motorcycle chain machine and jacking machine? Where are the parallel axes? Does anyone have a picture? The chain machine and the ejector machine are the two-stroke valve distribution methods of four-stroke motorcycles. That is, the components that control the opening and closing of the valve are the timing chain and the valve ejector rod respectively. The balance shaft is used to balance the inertial vibration of the crankshaft during operation. It is installed The weight is in the opposite direction of the crank, either in front of or behind the crank pin, as shown below.

Question 8: Motorcycle chain. The original chain of your car should be from CHOHO. Look, it is Qingdao Zhenghe chain.
Go to your local repairman who uses good parts and have a look. There should be Zhenghe chains for sale. Their market channels are relatively wide.
Question 9: How do you check the tightness of a motorcycle chain? Where to look? 5 points You can use something to lift the chain up from below twice! If it’s tight, the movement won’t be much, as long as the chain doesn’t hang underneath!
Question 10: How to tell which one is the ejector machine or the chain machine on a motorcycle? There is basically only one kind of ejector machine on the market now, which is relatively easy to distinguish. There is a round pin on the left side of the engine cylinder, which is the rocker arm shaft, as shown in the picture below. This is an obvious sign to distinguish the ejector machine, and the chain machine There are relatively many types of machines, and there are many different brands and models. If it is not an ejector machine, it is a chain machine, so as long as it does not have the characteristics of an ejector machine, it is a chain machine.
