Frequently Asked Questions

AI
Most motorcycles use standard M20 x 2.5 threads, but some brands like BMW or specific Yamaha models may require different sizes. Always check your owner's manual or measure the existing cap before purchasing to ensure a proper seal.
CNC aluminum caps offer superior heat resistance and a premium look, making them ideal for high-performance bikes. Plastic or anodized caps are lighter and often cheaper, suitable for daily riders who prioritize function over aesthetics.
Some motorcycles, particularly certain BMW models, require a specific wrench to remove the stock oil filler cap. If your bike needs one, consider buying a replacement cap that includes the tool or purchasing the tool separately to avoid damage.
