Product Overview & Key Features

Asian-Specific Head Form Design: Originally designed for European head shapes; now re-engineered specifically for Asian head contours, providing a more comfortable and relaxed fit for Chinese and Asian riders.

1. Rally / Retro Form
2. Full Face Form
3. Open Face (Half) Form
4. Retro Form
High-Density EPS Buffer Layer: Premium quality high-density cushioning layer effectively absorbs impact energy, enhancing shock absorption and head protection.

Size Chart & Fitting Guide

How to Measure Your Head Circumference:

Use a soft tape measure.
Wrap it around the widest part of your head – above the eyebrow ridge (frontal bossing) at the front and over the prominent bump at the back of your head (occipital protuberance).
Include all hair in the measurement. Take several measurements to find the most accurate value.

Selection Suggestion:

Choose the size that corresponds to your measured head circumference. If your measurement falls between two sizes, we recommend selecting the larger size for a more comfortable fit.

How to Wear

Open the chin strap – Unfasten the quick-release buckle.
Widen the opening – Pull both side straps outward and parallel to the ground.
Put on the helmet – Pull the helmet down from the back of your head (do not pull it straight down from the front).
Adjust the fit – Rotate the helmet left and right so your ears settle comfortably into the ear pockets.
Fasten the strap — Buckle the chin strap and adjust it so it is snug against your chin, with no more than two fingers of clearance.
Final check – Shake your head; the helmet should not rotate independently on your head.

To remove: Reverse the process — pull the side straps outward, lift from the back of the head, and remove.

Cleaning and Maintenance

Cleaning

Wipe the shell with a soft, damp cloth. For stubborn dirt, use mild soap and water.
Do not soak or immerse the helmet in water.
Remove the inner lining (detachable) and wash it gently by hand in lukewarm water with mild detergent. Rinse thoroughly and air dry.
Do not use gasoline, solvents, or abrasive cleaners on any part.

Drying

Air dry the helmet and lining at room temperature, away from direct sunlight, radiators, or other heat sources.
Do not use a dryer or forced hot air — this may deform the EPS liner.

Storage

Store in a cool, dry place, away from direct sunlight.
Do not place heavy objects on top of the helmet.
Avoid hanging the helmet on sharp hooks that may damage the inner padding.

Periodic Inspection

Inspect the outer shell for cracks, dents, or deep scratches.
Check the EPS liner for compression or deformation.
Ensure the visor, ventilation switches, and buckle mechanism work properly.
Replace the helmet immediately if it has suffered a severe impact or if any component is worn/damaged.
