Reinfoced Non-Sealed Motorcycle Chain

Our Reinforced Non-Sealed Motorcycle Chain is a high-performance drive chain developed with an enhanced design based on the standard non-sealed motorcycle chain. Featuring upgraded materials and precision engineering, this chain delivers improved impact resistance, fatigue strength, and high-load capacity, ensuring more stable and long-lasting power transmission under higher torque and demanding riding conditions.

Features
Upgraded materials with reinforced 20Mn bushings for improved wear resistance
Grade 10 steel rollers offer enhanced impact and fatigue resistance
High-strength 30CrMnTi pins support higher torque transmission
45Mn steel structure for heavy-duty applications
High-viscosity lubricant ensures reduced wear under demanding conditions

Applications
Street motorcycles
Road motorcycles and upgraded power models
