Supplier's note

1. Three Breakthroughs:

   • The Pro Model’s heat-treated alloy steel achieves 35% higher durability than standard carbon steel, enabling use in extreme industrial environments.
   • The Advanced Model’s noise reduction (-8%) via optimized tooth geometry improves user comfort in machinery.
   • All versions feature forged construction, ensuring 20% stronger load-bearing capacity compared to cast alternatives.

2. Optimal Selection Guide:

   • Base Model: Ideal for standard motorcycles and light industrial use where cost-efficiency is prioritized.
   • Advanced Model: Best for heavy-duty machinery or motorcycles in harsh climates (e.g., off-road vehicles).
   • Pro Model: Suited for high-stress applications like racing engines or continuous industrial operations.

With the Pro Model’s 800 N load capacity, you can handle extreme torque demands without compromising reliability. Pair its low-noise design with a stainless steel chain for seamless performance in wet environments.
