Frequently Asked Questions

What are the numbers in D.I.D Chain for?

D.I.D Chain number means size. Drive chain also knows as “roller chain” originates in England, this technology has developed and measured by the “Inch” in United States.

What are the characteristics of D.I.D Chain?

D.I.D chains have excellent durability for all range of Motorcycle

Wear Resistance- it means that the chain retains low friction and increase overall durability against elongation when operating.
Fatigue Strength- continuous load capacity when the chain is damaged affected on the drive D.I.D chain use selected Hi-carbon steel, special heat treatment and made by high- technology process
Tensile Strength- tensile strength is breakage load capacity when the chain is damaged affected by maximum torque when driving starts.

Structure of Drive Chain

Pin- support all the load acting on the chain, together with the inner and outer plate, and when the chain is engaged with a sprocket, the pin slides as bearings.

Bushing- act to prevent the shock received through rollers when the chain is engaged with sprocket from being directly transmitted to pins, and also act as bearing along with the pins.

Roller- act to smoothly bend the chain when the chain is engaged with a sprocket to protect the chain from impact with the sprocket.

Inner/ Outer plate- plates are subject to repeated tension of the chain and sometimes a large shock.

Seal Ring- acts to seal the grease on parts of pin and Bushing area prevents wear elongation.

Grease- Lubricant parts of pin and Bushing area for low friction

What makes D.I.D no.1?

Because of our world class products and truly reliable quality of works, D.I.D motorcycle chain have been used by World Top Riders in many categories- MotoGP, AMA Super Sports, AMA Formula, AMA Superstock, AMA Motocross, & AMA Supercross

Common Problems of Chain and How to Solve it

PROBLEM	CAUSED BY	MAINTENANCE/ SOLUTION
Fracture of Pin, Bushings and Roller	1. Improper Lubrication 2. Corrosion of Chain 3.Wear of sprockets 4. Foreign Objects	1. Lubrication and Maintenance must be done on 500km/ride 2. Check the condition& lubrication and replace the chain with a new one 3. Replace the Sprocket with a new one 4. Immediately remove foreign objects
Run upon Sprocket Teeth	1. Excessive wear elongation of chain 2. Chain too lose 3. Worn Sprocket of deposit of foreign matter on tooth gap bottom	1. Replace an exclusively worn chain 2. Pay constant attention to the chain sag, correct by adjusting it according to the procedure stated in motorcycle instruction manual 3. Replace a worn sprocket immediately and remove foreign objects
Vibration of Chain	1. Chain too lose 2. Uneven wear elongation 3. Occurrence of stiff Link	1. Pay constant attention to the chain sag, correct by adjusting it according to the procedure stated in motorcycle instruction manual 2. Lubricate Properly 3. Replace the chain with stiff links
Abnormal Noise	1. Incorrect Alignment of Sprockets 2. Chain is excessively tensioned or slackened 3. Large wear elongation of chain or wear of sprocket 4. Improper Lubrication 5. Improper Combination of chain & sprockets	1. Check the chain adjuster on motorcycle to avoid shortening of chain life due to abnormal wear of sides of the link plate caused by misalignment 2. Pay constant attention to the chain sag, correct by adjusting it according to the procedure stated in motorcycle instruction manual 3. Replace a chain that is beyond tolerance and replace worn sprockets with new ones 4. Lubricate Properly 5. Use the correct chain size and sprocket sizes. Consider compatibility.
Stiff Link	1. Load in excess of tolerance 2. Incorrect alignment of sprockets 3. Corrosion of chain and Improper lubrication 4. Interference between plate and foreign material 5. Ingress of foreign matter into a bendable portion of chain	1. Replace with new ones by checking your motorcycle instruction manual 2. Check chain adjuster on motorcycle 3. Lubrication and maintenance must be done every 500km/ride, check the condition and lubrication and replace old sprocket with new ones 4. Remove foreign material 5. Remove the chain, wash and re-lubricate or replace the chain. install a case to prevent the ingress of sand and mud
Rotation of Pin	Excessive tension and Riding of chain over sprocket and corrosion of chain and Improper lubrication	Replace it with new ones by checking your motorcycle instruction manual
Fractured Chain	1. Fatigue Fracture 2. Ductile fracture of plates / fracture of pins by steer or bending 3. When the chain Rides over the Sprocket 4. Battery Liquid/ Anti frozen Materials 5. Interference with foreign materials	1. Fatigue fracture of plates & bending fatigue fracture is caused by a chain used for a long time at a load exceeding the maximum allowable tension. If the life before fatigue fracture is shorter than the expected life, replace your chain 2. Select a proper chain to avoid ductile of pins by shear or bending 3. Fracture caused when the chain rides over a sprocket is mainly due to wear elongation. Select a proper chain and practice correct lubrication 4. When battery acid liquid puts on a chain, that causes the chain breakage, so replace it with new one. Be sure to clean the chain when connected with anti-frozen materials like rock salt. 5. If foreign objects interfere with the running of chain or be caught, the chain is likely to be over loaded and its life will be shortened then break suddenly. Check the condition and remove foreign objects
Wear of Plates and Sprockets on their lateral sides	Incorrect alignment of Sprocket	Misalignment of Sprocket result in abnormal wear of sides of link plate, thereby shortening chain life. Check the chain adjuster on your motorcycle
