The DYLinkar 25-1 Motorcycle Timing Chain is an engine timing chain designed for the economy-oriented replacement market. As a B-level alternative to 25H, the thickness of the chain links has been adjusted from the conventional 1.02mm to 0.8mm, achieving lightweight and cost optimization while maintaining basic transmission accuracy. This chain is made of high-quality alloy steel and undergoes precise stamping and heat treatment processes, featuring stable tensile strength and excellent wear resistance. It can meet the usage requirements of conventional engine timing transmissions. The product is widely used in motorcycle engines with displacements ranging from 50 to 125cc, suitable for cost-sensitive mass production and after-sales replacement scenarios.

• Large-scale production of economic motorcycles - A new production line for 50-110cc curved-frame vehicles, scooters and agricultural motorcycles, suitable for vehicle platforms with higher annual production volumes.
• Daily replacement in the after-sales repair market - As an economical alternative to 25H, it provides cost-effective timing system repair solutions for repair shops and end-users.
• Commute vehicles in Southeast Asia and South Asia - tailored to the local characteristic of a large number of Japanese and domestic motorcycles with a displacement of 100-125cc.
• City short-distance transportation vehicle - For household light motorcycles with relatively mild operating conditions and low annual mileage, this chain provides a more economical accessory option while ensuring basic reliability.
