To adjust a Kask helmet for a secure and comfortable fit, you'll need to work with both its innovative internal retention system and the classic chin straps. A proper adjustment ensures maximum safety and comfort while riding.
Mastering Your Kask Helmet's Fit
Kask helmets are renowned for their sophisticated fit systems, such as the Octo Fit or Up&Down Fit, which allow for precise adjustments to cradle your head perfectly. Alongside this, the chin straps secure the helmet firmly in place.
Adjusting the Internal Retention System (Octo Fit / Up&Down Fit)
The internal retention system, often featuring a cradle at the back of your head, is crucial for the helmet's stability and comfort.
- Initial Placement: Put the helmet on your head without fastening the chin straps. It should sit level, covering your forehead without tilting back or forward.
- Using the Adjustment Wheel: Locate the adjustment wheel (typically at the back of the helmet).
- To release the helmet or loosen the fit, turn the adjustment wheel in one direction (usually counter-clockwise).
- To tighten the helmet or snug the fit, turn the adjustment wheel in the opposite direction (usually clockwise).
- Adjust until the helmet feels firm but comfortable, without creating pressure points. It should not wobble when you move your head.
- Understanding Side Wing Movement: The system also includes side wings, which are part of the retention mechanism. These side wings will only ratchet inwards, meaning they can be tightened or brought closer to your head for a more custom, snug fit around the sides. This feature helps to cradle your head securely and prevent unwanted movement.
- Vertical Adjustment (if applicable): Some Kask models also allow for vertical adjustment of the rear cradle. If your helmet has this feature, you can move the entire retention system up or down to fine-tune its position on the back of your head for optimal comfort and stability.
Fine-Tuning the Chin Straps
Once the internal fit is set, adjust the chin straps for final security.
- Positioning the Y-Dividers: Ensure the strap dividers (the "Y" shaped buckles) sit comfortably just below your ears. These dividers can usually be slid up or down the straps to achieve the correct position.
- Tip: The straps should not rub against your ears or block your ear canal.
- Adjusting Chin Strap Length:
- Fasten the chin strap buckle under your chin.
- Pull the loose end of the strap to tighten it until it feels snug, but not constricting. You should be able to fit one or two fingers between the strap and your chin.
- Safety Check: Open your mouth wide. The helmet should press down slightly on the top of your head as the strap tightens. If it doesn't, the strap is too loose.
- Securing Excess Strap: Use the elastic loops or clips provided on the straps to secure any excess strap length, preventing it from flapping in the wind.
Quick Adjustment Checklist
| Step | Action |
|---|---|
| 1. Internal Fit | Place helmet level on head. Turn adjustment wheel to release the helmet, then tighten for snug fit. |
| 2. Side Wings | Ensure side wings will only ratchet inwards for a secure head cradle. |
| 3. Vertical Cradle (if present) | Adjust the rear cradle's height for optimal comfort. |
| 4. Y-Dividers | Position strap dividers just below your ears. |
| 5. Chin Strap | Fasten buckle, tighten strap until snug (one-to-two fingers fit). |
| 6. Final Check | Move head; helmet should not wobble. Open mouth; helmet should press down slightly. |
A correctly adjusted helmet is paramount for your safety and comfort, allowing you to focus on your ride with confidence. Regularly check your helmet's fit, especially after any impacts or prolonged storage.
