The HJC Y10 is a youth-size full-face motorcycle helmet for smaller heads. This collection brings together the solid Semi Flat Black finish and the Frank and Mika graphics, all sharing the same shell, visor system and three-size fit range. Colour can be the fun part of choosing, but an accurate fit must come first.
HJC lists YS for 48–49 cm, YM for 50–51 cm and YL for 52–53 cm. These measurements are a starting point rather than a substitute for checking the helmet on the child's head.
The chin bar and visor provide the enclosed format of an adult full-face helmet, scaled for young riders. The shell uses HJC's Advanced Polycarbonate Composite construction.
The supplied clear HJ-50 outer visor is anti-scratch coated and Pinlock-ready. A compatible insert is a separate, model-specific item unless a product listing states otherwise.
The crown liner and cheek pads are removable and washable. HJC also lists moisture-wicking, quick-drying interior fabric and cheek pads that can be exchanged across Y10 sizes.
Measure around the widest part of the head, keeping the tape level above the eyebrows and ears, then compare that figure with HJC's centimetre sizes. A new helmet should feel evenly snug without sharp pressure points. Check that the crown sits level, the eye opening is correctly positioned and the helmet does not rotate independently when gently moved.
HJC's ACS ventilation channels move air from front to rear, while the micro-buckle fastening is designed for straightforward adjustment. The Y10 is also listed as universally Bluetooth compatible, although the suitability and positioning of any communication equipment should be checked carefully for the rider and helmet size.
Clean the visor with lukewarm water and a soft cloth. Wash removable fabric parts according to HJC's care guidance and let them dry naturally before refitting. Replace the helmet after an impact or if the shell, fastening or energy-absorbing liner may have been damaged.
Moto Central keeps the current solid and graphic options together so the decision can stay focused on size and fit before colour. For alternatives, explore the wider HJC helmet collection or compare other motorcycle helmets. Model-specific replacement parts can be found through helmet spares and accessories.
No. It is a youth-size model with its own YS, YM and YL range.
The HJ-50 visor is Pinlock-ready. Check the individual product contents because ready does not necessarily mean an insert is supplied.
No. They are graphic options on the same Y10 helmet platform and use the same sizing.
Choose the size that fits correctly now. Do not rely on extra room that allows the helmet to move.
