A BMX helmet for a young rider needs to match head circumference first, then the kind of riding ahead. A child cruising a quiet street on a BMX needs a lighter multisport shell, while a child heading to a dirt track needs full-face coverage and a visor. Head size, strap adjustment, and ventilation shape daily comfort more than colour. The six options below split clearly between open-face multisport designs and full-face motocross designs, so matching the format to the riding plan matters most.
The Shortlist At A Glance
80SIX Triple Multisport Helmet for Kids, Teens & Adults
ILM Youth Dirt Bike Helmet Model 128YS Matte Black Youth-Large
ROOZO Youth Kids Dirt Bike Helmet Full Face Motocross Set 4-in-1
ILM Kids Youth Dirt Bike Helmet MT601Y Screw-Free Visor 11 Vents
Fly Racing Rayce MTB/BMX Bicycle Helmet Matte Grey Youth Large
Fly Racing Rayce MTB/BMX Bicycle Helmet Black Youth Large
The Strengths Of Each Pick
An open-face multisport shell suits neighbourhood BMX, scooters, and skate use without the bulk of a full-face design. The ABS shell, meaning a hard acrylonitrile butadiene styrene plastic outer layer, pairs with an EPS liner, meaning expanded polystyrene foam that absorbs impact energy. That combination keeps the shape familiar for younger riders who switch between bikes and boards.
Three size bands cover head circumference from 49 to 58 cm, and measuring with a string around the forehead gives a clearer result than age alone. An adjustable chin strap with a side-release buckle helps with a snug fit from the first ride. The interior foam pads shape gradually around the head, which suits a child who rides several times a week.
The Good Stuff
- Meets CPSC bicycle, ASTM F1447, and ASTM F1492 standards for cycling and skate use
- Three sizes from 49-52 cm through 55-58 cm for growth stages
- Ventilated shell shape suits longer sessions at the park
- Side-release buckle allows quick removal without loosening straps
- Single helmet covers biking, skating, and scooter riding
Things To Consider
- Open-face design leaves the chin and face uncovered on dirt tracks
- Size bands overlap, so a careful circumference check matters before ordering
Full-face coverage changes the picture compared with the open-face 80SIX model, adding chin protection for dirt, ATV, and motocross riding. The lightweight ABS shell and thick EPS liner meet FMVSS-218 and DOT standards for motorcycle helmets. That standard matters for motorised use in a way bicycle standards do not.
Front and rear vents move air through the shell during warm rides, and the detachable visor angles to block sun without a separate peak. Removable washable inner pads help after dusty sessions, and extra pads can be requested for a closer fit. Measuring about one inch above the eyebrows gives the most useful size reference.
The Helpful Details
- Full-face shell with DOT FMVSS-218 standard compliance
- Front and rear vents support airflow on long rides
- Detachable visor adjusts for sun angle
- Washable inner pads simplify cleaning after dirt rides
Worth Noting
- Full-face weight suits older youth better than very young children
- Matte black finish shows dust more readily on trail days
- Size guidance from the maker works as a guide, so circumference checks help
Who It Suits Best
Older youth riders on dirt bikes, ATVs, and off-road trails who need chin coverage.
Where Another Pick Suits Better
The ROOZO Youth Kids Dirt Bike Helmet Full Face Motocross Set 4-in-1 suits beginners who want goggles and gloves included.
A bundled kit approach sets this full-face option apart from the standalone ILM Model 128YS, since goggles and gloves arrive in the same package. The ABS shell and dense EPS liner meet DOT FMVSS-218 standards, and the listed weight sits at 2.38 lb. Lighter weight matters for younger riders during longer trail sessions, where neck fatigue shows up sooner.
Top and chin vents direct air toward heat zones, while an adjustable visor blocks sun and keeps peripheral vision open. A quick-release buckle allows one-hand removal, and the breathable liner can be washed after sweaty rides. Four sizes from 49-50 cm to 55-56 cm cover a wide youth range.
Where It Excels
- Helmet, anti-fog goggles, and gloves in one set
- 2.38 lb listed weight eases strain on younger necks
- Adjustable visor with strong UV blocking for sunny tracks
- Washable sweat-wicking liner refreshes between rides
- One-hand quick-release buckle for fast removal
Trade Offs
- Kit sizing must match goggles and gloves at the same time
- Full-face format adds bulk compared with open-face multisport shells
Eleven vents and a screw-free visor give this ILM model a different feel from the ROOZO kit, with airflow as the main story. The ABS shell and high-density EPS liner meet FMVSS-218 and DOT standards for dirt bike, ATV, BMX, and off-road use. A listed weight of 2.3 lb keeps pressure lower during extended riding.
Mouth and side vents reduce stuffiness, and a nose guard helps block sand and dust on loose trails. The bundle adds gloves, a balaclava face mask, and UV-resistant goggles with sponge cushioning. Snap fasteners hold the removable brim firmly while allowing quick removal.
Reasons It Performs
- 11 vents target airflow at mouth and sides
- Screw-free visor detaches cleanly without loose screws
- Gloves, balaclava, and goggles included in the set
- 2.3 lb weight suits longer rides for younger riders
Minor Gripes
- Snap-fastened brim needs a firm check before fast riding
- Bundle extras add storage space in a small garage
- Full-face shape runs warmer than open-face options in summer
Gravity riding gets the focus here, with a poly-alloy shell and EPS liner built for downhill, BMX, and bike-park laps. Standards include ASTM F1952-15 for downhill, CPSC 1203, and CE EN1078 for cycling use. That downhill standard separates this design from general motocross shells.
At roughly 930 g in size M, the shell feels lighter than the 2.3 lb motocross options, which helps during repeated laps. A TFV airflow system, meaning multiple intake and exhaust ports, moves heat out in warm conditions. A D-ring strap, meaning two metal rings for a secure closure, plus an adjustable visor with aluminium hardware, complete the setup.
Noteworthy Benefits
- Downhill standard ASTM F1952-15 for gravity riding
- Approx. 930 g weight in size M for lap after lap
- Removable washable liner with cheek pads
- D-ring closure for a secure, race-style fit
- Adjustable visor with aluminium hardware
Room For Improvement
- No goggles or gloves included, unlike the bundled motocross sets
- Full-face bicycle design suits gravity riding more than casual street use
Fly Racing Rayce MTB/BMX Bicycle Helmet Matte Grey Youth Large
Made For
Youth riders focused on downhill, BMX racing, and bike-park laps.
Consider Something Else When
The 80SIX Triple Multisport Helmet for Kids, Teens & Adults suits casual street and skate riding at a lighter commitment.
Colour is the main difference from the matte grey version, with the same poly-alloy shell and EPS liner underneath. The design targets downhill, BMX, and bike-park riding, meeting ASTM F1952-15, CPSC 1203, and CE EN1078 standards. Black suits riders who prefer a darker finish that hides scuffs from regular use.
TFV ventilation uses intake and exhaust ports to keep air moving during warm sessions, and the removable liner with cheek pads can be washed between rides. A D-ring closure and adjustable visor with aluminium hardware mirror the grey model exactly. In most bike-park settings, colour choice comes down to personal preference rather than performance.
Notable Upsides
- Same downhill-standard shell as the matte grey version
- Approx. 930 g weight in size M for extended laps
- Washable liner keeps interior fresh between sessions
- Black finish suits riders who prefer a darker look
Points To Note
- Identical build to the grey version, so colour drives the choice
- Helmet only, with no bundled goggles or gloves
What Matters Most Before Choosing Bmx Youth Helmets
Head Circumference Before Age Labels
Age ranges overlap across brands, while circumference bands stay consistent. Measure around the forehead with a soft tape or string, then match that number to the size chart. A snug fit with even pressure around the head matters more than a loose fit with room to grow.
Open Face Versus Full Face
Open-face multisport shells suit street BMX, scooters, and skate parks, where airflow and quick removal matter. Full-face shells add chin coverage for dirt tracks, downhill runs, and motorised riding. The riding surface decides the format, and mixing the two uses rarely works well.
Weight, Vents, and Washable Liners
Lighter shells reduce neck strain during long sessions, especially for younger riders. Vents at the chin, mouth, and top move heat out on warm days, and removable liners allow washing after dusty or sweaty rides. Those three details shape comfort far more than colour or graphics.
Key Considerations Across These Picks
Common Shopping Slip Ups
Ordering by age alone leads to loose fits, since head sizes vary widely within an age band. Skipping a circumference check and relying on a general size label causes most returns. Measuring first and checking strap adjustment avoids that problem.
What The Higher Tier Buys
Higher-tier shells add downhill-specific standards, lighter poly-alloy construction, and race-style closures. Those upgrades pay off for riders spending full days at a bike park or track. Casual street riders gain little from gravity-focused features.
Frequently Asked Questions
What size BMX helmet does a young rider need?
Head circumference decides the size, not age alone. Measure around the forehead and match that measurement to the listed size band.
Is a full-face helmet needed for BMX riding?
Street BMX riding suits an open-face multisport helmet with bicycle standards. Dirt tracks and downhill runs call for full-face coverage with chin protection.
How often should helmet liners be washed?
Washable liners can be cleaned after dusty or sweaty sessions. Regular washing keeps the interior fresh and helps maintain a snug fit.
What ventilation matters on warm riding days?
Chin, mouth, and top vents move heat away from the face during exertion. Multiple intake and exhaust ports help more than a single large opening.
Can one helmet cover biking and skateboarding?
Multisport shells with bicycle and skate standards cover both activities. Full-face motocross shells suit motorised and dirt riding instead.
Final Thoughts
Match the format to the riding plan first, then measure head circumference carefully. Street and skate use points toward the 80SIX multisport shell, while dirt and gravity riding points toward full-face options from ILM, ROOZO, or Fly Racing. A measured fit and the right standard for the activity matter most.
