| Cast Iron Flywheel Weights | Heavy-duty motorcycles, budget builds | 10 oz (283g) (heavier), Corrosion resistance: 50 hours (ASTM B117 salt spray test) | Cost-effective, high load capacity (10,000 N ASTM E8) | Prone to rust, energy loss due to weight ▲ (heavier than steel) |
| Steel Flywheel Weights | Standard motorcycles, moderate use | 7 oz (200g), Corrosion resistance: 100 hours (ASTM B117) ▲, Durability: 5000 cycles (ASTM E8) | Lightweight, better corrosion resistance than cast iron | Moderate corrosion protection, requires frequent maintenance in harsh conditions |
| Stainless Steel Flywheel Weights | High-performance bikes, coastal regions | 7 oz (200g), Corrosion resistance: 200+ hours (ASTM B117) ▲, Noise: 43 dBA (quieter than refrigerator hum) | Superior corrosion resistance, silent operation ▲, lightweight | Higher cost, specialized installation needed |
| Aluminum Flywheel Weights | Lightweight racing bikes, noise-sensitive use | 5 oz (142g) ▲, Noise: 38 dBA (quieter) ▲, Thermal stability: -40°C to 120°C (ASTM D648) | Extremely lightweight, ultra-quiet operation | Lower load capacity (max 8000 N), prone to wear in high-torque scenarios |
| Composite Flywheel Weights | High-end motorcycles, extreme environments | 6 oz (170g), Durability: 10,000 cycles (ASTM E8) ▲, Chemical resistance: ASTM D543 (50+ chemical exposures) | Lightweight and durable, chemical-resistant ▲, customizable weight distribution | High cost, limited availability, requires expert fitting |
| Customizable Flywheel Weights | Custom builds, specialized applications | Customizable weight (5–10 oz), Custom finishes (matte/polished ▲), Thickness: 2–4 mm (ISO 3801) | Tailored performance and aesthetics, adaptable to unique engine specs | Higher cost, longer lead times, requires design collaboration |
