Getting your child ready for their first season of motocross is an exciting adventure, but it can also feel overwhelming. With a wide range of brands, sizes, and prices available, it’s all too easy to either overspend on gear that they’ll outgrow in just a few months or cut corners on safety equipment, which is definitely not something to trade off. That’s where this kids motocross boots and helmet guide comes in to help simplify your decision-making.
At Moto Sport Services, we’ve been equipping young riders since 1986. As a family-run shop, many of us grew up riding motocross ourselves, so we truly understand what parents are after: gear that keeps kids safe, fits well, and doesn’t damage the pocket. In this guide, we’ll cover everything you need to know before making a purchase, including sizing, safety standards, and some budget-friendly tips.
Why Proper Motocross Kit Matters More for Kids Than Adults
Choosing children’s motocross gear is more challenging than just downsizing an adult kit. As kids grow quickly, gear that fits well in spring may be too tight by autumn, so it’s essential to consider their growth whilst ensuring proper protection. Young riders have underdeveloped reflexes and body awareness, making a correct fit crucial for safety. Additionally, uncomfortable gear can affect a child’s confidence and Therefore, take your time selecting the two most important items: the helmet and the boots.
Choosing the Best Beginner Dirt Bike Helmet for Kids
The helmet is the single most important piece of safety equipment your child will wear, so it’s worth getting right. Start with certification, then move on to fit and ventilation.
Look for ECE 22.06 Certification
In the UK, motocross helmets should meet the ECE 22.06 safety standard, the current certification required for road and track use across the UK and EU. This replaced the older ECE 22.05 standard, with tougher testing across a wider range of impact speeds and angles, plus rotational impact testing that wasn’t part of the previous standard. When browsing helmets, check the label or product listing for ECE 22.06 approval. If you’re ever unsure whether a helmet meets current standards, just give us a call, and we’ll confirm it for you.
Getting the Fit Right
A correctly fitted helmet should feel snug all the way around, without any pressure points. Here’s how to check:
- Measure head circumference with a soft tape measure just above the eyebrows and ears, and use this against the manufacturer’s size chart rather than guessing by age.
- Check for movement. With the chin strap fastened, the helmet shouldn’t rock forward, backward, or side to side. If your child can move the helmet without their head moving with it, it’s too big.
- Cheek pads should sit snugly against the face without being painfully tight. Some looseness will settle in as the padding compresses with use, but it shouldn’t be loose from the start.
- Never buy “room to grow.” Unlike boots, helmets should never be sized up in the hope your child grows into them. A loose helmet can shift on impact and fail to protect properly.
Ventilation and Weight
Kids overheat faster than adults, especially on hot summer days out on the track. Good airflow through vents matters for comfort and concentration, not just temperature. Lighter helmets also reduce neck fatigue, which is especially important for younger, smaller riders who haven’t yet built up much neck strength.
When to Replace a Helmet
This is one area where we’d always rather talk you through it over the phone than let you guess. As a general rule:
- Replace after any crash, even if there’s no visible damage. The internal foam liner is designed to absorb impact once, and often that damage isn’t visible from the outside.
- Replace every 3–5 years even without a crash, as materials degrade over time.
- Replace if it no longer fits properly; don’t be tempted to keep using an outgrown helmet “for now.”
If you’re ever unsure whether a helmet is still safe to use, give us a call on 01744 612902, and we’ll talk you through it; our advice is always free. And if you’re local to St. Helens, feel free to pop into the shop and try a few on in person; there’s no substitute for checking the fit yourself before you buy.
Youth Motocross Boots Sizing: Room to Grow vs Proper Ankle Support
This is one of the most common questions we’re asked in-store. Boots are a bit different to helmets in that a small amount of growing room is generally acceptable, but only within limits, and never at the expense of proper ankle support.
Why Ankle Support Can’t Be Compromised
Motocross boots are built to protect the ankle and lower leg from twisting injuries, which are among the most common injuries in the sport. A boot that’s too big will move around inside, meaning the rigid ankle support doesn’t sit where it needs to when your child comes off the bike or lands awkwardly. Loose boots can also affect a child’s control over the foot pegs and gear lever, which becomes a safety issue in its own right.
Our Rule of Thumb for Sizing
- Aim for a snug fit with socks on, allowing for a small amount of room, not a full size or more of extra space.
- Buckles should snap shut tightly, without gapping.
- If your child is between sizes, it’s usually better to go up a size rather than down, but this should be a small step, not a guess at “next season’s size”.
- Children’s feet grow at different rates, so where possible, it’s worth trying on boots in person or carefully checking sizing against the individual brand’s chart, as sizing varies between manufacturers.
If you’re ordering online and aren’t sure which size to pick, this is exactly the kind of thing we’re happy to help with over the phone; we’d rather spend five minutes getting it right than have you dealing with a return.
Recommended Fox and Alpinestars Youth Boots In Stock
We stock a wide range of Fox youth boots and other leading brands, but two ranges consistently stand out for first-time buyers in terms of protection, durability, and value. Both come up regularly in conversations with parents working through their own kids motocross boots and helmet guide before ordering.
Fox Youth Comp Boots
Our Fox Youth Comp boots are a solid, dependable choice for young riders who are just starting. They offer real protection, support, and comfort without the price tag of top-tier race boots, ideal for kids who are still growing and where you don’t want to overspend on the top-of-the-range option straight away.
Alpinestars Tech 7S Youth Boots
This range sits a step up, offering the kind of premium protection and flexibility more commonly associated with adult race boots, scaled down properly for younger riders. If your child is riding regularly or progressing quickly, these are worth the investment.
Both ranges are part of our full youth kit selection, which you can browse in our helmets, clothing & boots category.

Full Kit Checklist: Helmet, Boots, Gloves, Body Armour
Helmets and boots get most of the attention, but a proper first kit setup includes a few more essentials worth budgeting for:
- Helmet: correctly sized, ideally with good ventilation for summer riding.
- Goggles: fitted to work with the helmet, with a tear-off or clear lens depending on conditions.
- Boots: snug fit with ankle support, minimal growing room.
- Gloves: should allow full grip and clutch/brake control without being loose.
- Body armour: chest, elbow, and knee protection at minimum. Our Fox Pee Wee armour set (chest, elbows & knees) is a popular starting point for younger riders and is often available as a bundle.
- Neck brace (optional but increasingly common): worth discussing with us if your child is moving beyond casual riding into regular track time.
- Casual/off-bike kit: we also stock Fox casual clothing, handy for kids who want to look the part off the bike too.
Trying to buy everything at once can feel like a big spend, so it’s worth prioritising the helmet and boots first, then building the rest of the kit around your budget and how often your child will be riding.
Budget Tips: Buying End-of-Season Stock and Old Models
Motocross gear isn’t cheap, and kids outgrow it quickly, so it’s worth being smart about where you spend and where you save.
Buy end-of-season or previous-model stock where safety isn’t affected.
Boots and armour from the previous year’s range often perform identically to the current model; you’re mainly paying extra for updated colours and graphics on the newest release.
Watch for bundle offers.
We regularly run offers where buying items together, like a full armour set, works out cheaper than buying separately.
Don’t oversize on safety gear to save money long-term.
It’s tempting to buy bigger to get more wear out of a helmet or boots, but as covered above, this compromises protection. Save money elsewhere in the kit instead.
Ask about current offers before you order.
Our in-stock offers change regularly, and we’re always happy to point you toward the best value option for your child’s size and riding level rather than just the most expensive one.
If there’s a cheaper alternative that we’ve tested and rated, we’ll tell you about it rather than pushing the priciest option.
Frequently Asked Questions
1. What size motocross helmet does my child need?
Measure their head circumference with a soft tape measure above the eyebrows and ears, then match it to the manufacturer’s size chart. Never buy a helmet with room to grow; it should fit snugly from day one.

Replace it immediately after any crash, even without visible damage, and every 3–5 years regardless of use, as materials degrade over time.
