Description
Motorcycle chains are created from high-precision components with heat treatment and shot peening to increase strength and durability. Our motorcycle chains are all pre-stretched to seat the ingredients to minimize initial elongation and pre-lubricated with high-quality lubrication from the factory before shipping out.Â
Features
- Heat treatment for improved strength  Â
- Shot peened for improved fatigue strength  Â
- Pre-stretched to minimize initial elongation
- Pre-lubricated with high-quality lubrication from the factory

Silent chain drives can transmit power with low noise and reduce vibration, allowing your motorcycle to drive smoother and more quietly. The faster the silent chains run, the more significant difference is between the usual chains.
The construction of the silent chain is quite simple: only pins and plates.Â
The plates have a link plate and a guide plate.Â
The flat and tooth-shaped link plates reduce impact and noise when they engage with the sprockets.
The guide plates are installed on the outer side of the chain to help to maintain proper operation on sprockets.
Features
- Low noise and reduced vibration
- Heat-treated componentsÂ
- The edge of the plates is smoothened (some specifications) to reduce wearing with a tensioner and guide.
