Part Description
Haotian Arrow HT125-4F 11 Chain DID Standard Grade
One Spring Link supplied with chain.
DID Standard Chain
Although DID S Standard chain represents DID's simplest grade of chain, it still features the finely-tuned engineering and high-quality control that DID is so well known for, using the latest in Japanese chain technology.
The bushing on a chain is important for impact and wear resistance, and helps to absorb the shock from the rollers rather than directly transmitting it to the pins. By using rigid, seamless, solid bushes, instead of curled bushes that other manufacturers use, the wear life of a DID Standard chain can be 1.2 to 4 times the life of a chain using curled bushings.
All DID chains are made in Japan.
| Pin Length | Roller Diameter | Plate Thickness | Weight | Tensile Strength |
|---|---|---|---|---|
| 16.70mm | 8.50mm | 1.5mm | 0.84kg per 100 links | 18.8KN |
If the original equipment chain was an O-Ring or X-Ring chain it must not be replaced with a standard chain. It must be replaced with a sealed chain of equal or greater strength.

Delivery and Returns
We want you to be happy with your purchase. If you're not, just return the products to our warehouse. Unless faulty, we'd like this to be within 30 days of purchase. Exceptions apply to certain products.
Basics
A motorcycle chain comprises two precision ground pins peened at each end as a rivet, two bushes, two rollers and two side plates. A further pair of outer side plates join each link to the next link. In O ring chain a round seal is fitted on the pin between the plates to retain lubricant. The seal is contoured for less drag in X ring chains.
The Number of links is measured by the number of pitches, which is the gap between each pin or rivet and includes a Spring/clip or Rivet link to give an even number.
Please note that we supply lengths of chain to fit standard sprockets. When using sprockets with 2 or more extra teeth a chain with more links is often needed. Feel free to call for any assistance.
Metric Dimensions
| Chain | Pitch | Width | Roller Diameter |
|---|---|---|---|
| 415 | 12.70mm | 4.88mm | 7.75mm |
| 420 | 12.70mm | 6.35mm | 7.75mm |
| 428 | 12.70mm | 7.75mm | 8.51mm |
| 520 | 15.88mm | 6.35mm | 10.16mm |
| 525 | 15.88mm | 7.85mm | 10.16mm |
| 530 | 15.88mm | 9.53mm | 10.16mm |
| 532 | 15.88mm | 9.53mm | 11.10mm |
| 630 | 19.05mm | 9.53mm | 11.91mm |
| 632 | 19.05mm | 9.66mm | 12.68mm |
Side plate thickness varies with grade and make of chain. As a rule, 1.5 to 2.6 mm. It is important for safety to join chain with the manufacturers correct Rivet Soft Link or Split Spring Link.
Size, Manufacturer, and grade are often stamped on some of the side plates.
Replacing The Drive Chain
The chain will naturally stretch as it wears. On a non-sealed chain this should not exceed 3% of its original length. Sealed chain stretch should not exceed 1% of its original length. If the stretch exceeds this it needs to be replaced.
Tension Adjustment
A drive chain that carries too much tensions speeds up wear by excessive amounts of pressure being placed on the sprocket teeth, chain joints and the gearbox main-shaft bearings. One that is too loose is at risk of a whip action that may cause it to snap. Having an incorrect tension can also cause the chain to stretch.
Normal sag is 3/4"; to check, press down on the top strand of the drive chain with your fingers. Tighten or loosen to achieve the desired sag. Note this should be performed with the weight of the rider on the bike. It is advised to check your manufacturer's handbook for your particular machine.
Sprocket alignment
Misaligned sprockets can greatly reduce chain and sprocket life. Check sprocket alignment periodically to ensure they are straight.
The complete guide to checking, removing, replacing and maintaining your chain and sprockets. Professionally filmed in our studio, Nick Hine shows you exactly how to do each job - with clear, close-up shots, tips, advice and techniques that enable you to get a professional finish - even if you have no experience.
All DVDs start and end with the bike on the ground, They don't miss out any steps and always use standard home garage tools where possible and show you how to make your own special tools where necessary. We explain why you need to do each task and try to give you a good understanding of the principles behind each job.
THIS COMPREHENSIVE 35 MINUTE DVD SHOWS YOU HOW TO
- Check and assess your chain and sprockets for wear
- Safely jack and support your bike
- Correctly remove different types of chain
- Replace each component independently
- Fit your new split link correctly
- Adjust and maintain your new chain
