3.1 Kask Takma
Proper helmet fit is crucial for safety and comfort. Follow these steps to ensure your Sena U1 helmet fits correctly:
- Measure Your Head: Use a flexible tape measure to find the circumference of your head, roughly 1 inch above your eyebrows and the top of your ears. Compare this measurement to the sizing guide below to select the appropriate helmet size.
- Adjust the Dial: Before placing the helmet on your head, open the dial adjustment at the back to its widest setting.
- Kaskı yerleştirin: Place the helmet on your head, ensuring it sits level and covers your forehead without tilting too far forward or backward.
- Tighten the Dial: Gradually tighten the dial adjustment at the back until the helmet feels snug but comfortable. It should not be too tight or cause pressure points.
- Buckle the Chin Strap: Fasten the chin strap. It should be loose enough to allow you to move your mouth, but tight enough that you can only fit two to three fingers between your chin and the strap.
- Yan Kayışları Ayarlayın: Adjust the buckles on the side straps so they form a 'V' shape just below your ears and lie flat against your head.
