Navigating motocross (MX) gear sizing is crucial for performance and safety; accurate measurements ensure comfort, control, and confidence while riding.
What is MX Sizing?
MX sizing refers to the standardized measurements used to determine the correct fit for motocross gear, encompassing helmets, jerseys, pants, gloves, and boots. Unlike standard apparel sizing, MX sizing often differs due to the specific demands of the sport – requiring a more athletic, performance-oriented fit that allows for a full range of motion and accommodates protective gear.
Manufacturers like Thor and Seven MX provide their own sizing charts, as these can vary between brands and even between different product lines within the same brand. These charts typically utilize body measurements such as chest size, waist size, inseam, and head circumference to recommend the appropriate size. Understanding that these charts are guidelines, and individual preferences can influence the ideal fit, is essential.
Accurate MX sizing isn’t simply about aesthetics; it’s fundamentally linked to rider safety and performance. Ill-fitting gear can restrict movement, cause discomfort, and even compromise protection in the event of a crash.
Why Accurate MX Sizing Matters
Precise MX sizing is paramount for several critical reasons, directly impacting a rider’s safety, comfort, and overall performance on the track. Ill-fitting gear can severely hinder movement, creating a distraction and increasing the risk of crashes. A jersey that’s too tight restricts arm motion, while pants that are too loose can bunch up and interfere with bike control.
Furthermore, a properly fitted helmet is non-negotiable for head protection. Too large, and it won’t stay securely in place during impact; too small, and it can be uncomfortable and potentially compromise vision. Similarly, gloves must provide a secure grip without constricting hand movement.
Investing time in accurate measurements and referencing manufacturer sizing charts – like those from Thor and Seven MX – ensures a comfortable, secure fit. This allows riders to focus entirely on their riding, maximizing control, confidence, and minimizing the risk of injury.
Helmet Sizing
Selecting the correct helmet size is vital for safety and comfort; proper fit ensures maximum protection during impacts and optimal rider focus.
Measuring Your Head for a Helmet
Accurate head measurements are the foundation of proper helmet sizing. Begin by using a flexible measuring tape, positioning it horizontally around the largest circumference of your head – approximately one inch above your eyebrows and just above your ears. Ensure the tape is level all the way around.
Repeat the measurement two or three times to confirm accuracy, noting the largest measurement. It’s helpful to have a friend assist you for a more precise reading. Don’t pull the tape too tightly; it should be snug but not constricting.
Consider your hair style; if you frequently wear your hair in a ponytail or with added volume, account for this when measuring. Once you have your head circumference in centimeters or inches, refer to the specific helmet manufacturer’s sizing chart (like Thor or Seven MX) to determine your corresponding helmet size. Remember, sizing can vary slightly between brands.
Thor MX Helmet Sizing Chart
Thor MX helmets generally follow a standard sizing structure, but it’s vital to consult their specific chart for the most accurate fit. Typically, a head circumference of 51-52cm corresponds to a Small (S) helmet, while 53-54cm fits a Medium (M). Larger heads, measuring 55-56cm, require a Large (L), and those exceeding 57-58cm need an Extra-Large (XL).
However, Thor’s charts may include half sizes or variations depending on the helmet model. Always prioritize checking the chart associated with the exact helmet you are considering purchasing. Some models may run slightly smaller or larger than others.
Remember that these are guidelines; individual head shapes can influence fit. If your measurement falls between sizes, it’s generally recommended to size up for a more comfortable and secure fit. A properly fitted helmet should feel snug without creating pressure points.
Seven MX Helmet Sizing Chart
Seven MX helmets, like other brands, utilize head circumference measurements to determine the appropriate size. A head measuring 51-52 cm typically corresponds to a Small (S) size, while 53-54 cm suits a Medium (M). Riders with a 55-56 cm head circumference generally require a Large (L), and those measuring 57-58 cm will need an Extra-Large (XL).
It’s crucial to consult the specific sizing chart for the exact Seven MX helmet model you’re interested in, as variations can occur. Some models may have a different internal shape or padding, impacting the overall fit.
When in doubt, especially if your measurement falls between sizes, it’s often advisable to choose the larger size. A secure, yet comfortable, fit is paramount for safety and performance. Ensure the helmet doesn’t feel overly tight or create pressure points during wear.
Helmet Sizing: Key Considerations
Beyond simply measuring your head circumference, several factors influence helmet fit. Head shape plays a significant role; some helmets are better suited for rounder heads, while others accommodate more oval shapes. Consider the helmet’s internal padding and liner – thicker padding can affect sizing.
Always prioritize a snug, but comfortable, fit. The helmet should not move excessively on your head, either front-to-back or side-to-side. Cheek pads should press firmly against your cheeks, and the brow should be adequately covered.
Proper helmet fit is non-negotiable for safety. A loose helmet offers reduced protection in the event of an impact. Regularly check the fit, especially after extended use, as padding can compress over time. Don’t compromise – a well-fitted helmet is the most important piece of MX gear.
Jersey Sizing
MX jersey sizing typically focuses on chest measurements to ensure a comfortable, athletic fit that allows for unrestricted movement during aggressive riding sessions.
Measuring Your Chest for a Jersey
Accurate chest measurement is the foundation of finding the right motocross jersey size. To begin, stand naturally with your arms relaxed at your sides. Have a friend assist you for the most precise reading. Wrap a flexible measuring tape around the fullest part of your chest, ensuring the tape is level and snug, but not overly tight.
Avoid measuring over clothing, as this will add unnecessary bulk and lead to an inaccurate measurement. Breathe normally during the measurement process – do not suck in your stomach or puff out your chest. Record the measurement in inches or centimeters, depending on the sizing chart you are referencing.
It’s often helpful to repeat the measurement a couple of times to confirm consistency. If your measurement falls between two sizes on the chart, consider your build and preferred fit. A more athletic or muscular build might benefit from sizing up, while a slimmer build may prefer to stay with the smaller size. Remember to always consult the specific brand’s sizing chart, as variations can occur.
Thor MX Jersey Sizing Chart
Thor MX jerseys generally follow a standard sizing convention, but it’s vital to consult their specific chart for the most accurate fit. Typically, Thor’s sizing correlates with chest measurements. For example, a Small jersey usually fits chest sizes between 34-36 inches, Medium fits 38-40 inches, Large accommodates 42-44 inches, and Extra Large suits 46-48 inch chests.
However, these are approximate guidelines. Thor often provides detailed charts on their website and retailer pages, listing specific measurements for each size in both inches and centimeters. Pay close attention to any notes regarding the jersey’s cut – some are designed for a more athletic, fitted style, while others are looser and more relaxed.
Always double-check the chart corresponding to the specific jersey model you are considering, as slight variations can exist between different lines. Utilizing this chart will help dial in your fit for comfort, control, and confidence during your ride.
Seven MX Jersey Sizing Chart
Seven MX jerseys are engineered for high-performance riding, and accurate sizing is paramount for unrestricted movement. Their sizing charts typically base recommendations on chest circumference, similar to other MX brands, but it’s crucial to verify the specific chart for each jersey model.
Generally, a Small Seven MX jersey fits a 34-36 inch chest, Medium suits 38-40 inches, Large accommodates 42-44 inches, and Extra Large is designed for 46-48 inch chests. However, Seven MX often incorporates athletic cuts, meaning the jerseys may fit slimmer than traditional styles.
Therefore, carefully review the detailed sizing chart available on the Seven MX website or through authorized retailers. Note any specific fit information provided, such as whether the jersey is designed to be worn tucked in or untucked. Prioritizing accurate measurements ensures optimal comfort and performance on the track, allowing you to focus on your ride.
Jersey Sizing: Fit Preferences
Motocross jersey fit is largely a matter of personal preference, influencing both comfort and performance. Some riders prefer a looser fit, allowing for maximum airflow and unrestricted movement, particularly in warmer conditions. This style often involves sizing up from the recommended measurement.
Conversely, others favor a more athletic, snug fit that minimizes bunching and keeps the jersey securely tucked into their pants. This preference typically aligns with sizing down or selecting the size corresponding to their exact chest measurement.
Consider your riding style and the climate when choosing a jersey size. Aggressive riders who prioritize freedom of movement may lean towards a looser fit, while those focused on a streamlined profile might prefer a tighter one. Ultimately, the ideal fit should feel comfortable and allow you to ride without distraction.
Pant Sizing
Proper motocross pant sizing hinges on accurate waist and inseam measurements, ensuring optimal mobility and comfort during aggressive riding and varied conditions.
Measuring Your Waist and Inseam
Accurate waist measurement is fundamental for motocross pant fit. Stand naturally and measure around your natural waistline, keeping the tape measure comfortably loose – do not cinch it tightly. Record this measurement in inches. For the inseam, wear the boots you intend to ride in. Have someone measure from your crotch down the inside of your leg to the top of your boot.
Ensure the tape measure is straight and taut. This inseam length is critical for preventing the pant from being too short, restricting movement, or too long, creating bunching and potential hazards. It’s always better to err slightly on the longer side, as a little extra length can be accommodated with adjustments, but a pant that’s too short is unusable. Double-check both measurements before consulting the sizing chart for your chosen brand, as variations exist between manufacturers.
Thor MX Pant Sizing Chart
Thor MX pant sizing generally correlates with standard US waist sizes, but it’s vital to consult their specific chart for the most accurate fit. As of late 2025/early 2026, Thor’s chart typically outlines waist measurements in inches and corresponding pant sizes (e.g., 30, 32, 34, 36, 38, 40, 42, 44, 46).
For example, a waist measurement of 32 inches usually corresponds to a size 32 pant. However, individuals between sizes should consider their build and preferred fit – a looser fit might be preferred for unrestricted movement, while a snugger fit offers a more streamlined feel. Always prioritize checking the official Thor MX sizing guide available on their website or through authorized retailers like Motorhelmets.com, as charts can be updated periodically. Remember to factor in the boots you’ll be wearing when determining the appropriate inseam length.
Seven MX Pant Sizing Chart
Seven MX pant sizing, similar to other brands, relies on accurate waist measurements to ensure optimal fit and performance.

It’s crucial to measure your waist accurately, as Seven MX pants are designed for a performance-oriented fit. Consider whether you prefer a more relaxed or athletic cut. If you fall between sizes, Seven MX often recommends sizing up for greater mobility on the track. Their fit guides emphasize finding the perfect balance between comfort and unrestricted movement. Always refer to the latest chart, as sizing can be updated. Seven MX also offers compression gear, so be mindful of layering when selecting your pant size for optimal comfort and control.
Pant Sizing: Importance of Mobility
Optimal mobility is paramount in motocross, and correctly sized pants are fundamental to achieving it. Restrictive pants hinder movement, impacting control and potentially leading to fatigue or injury. Pants that are too loose can bunch up, creating discomfort and interfering with bike control.
A proper fit allows for a full range of motion – bending, twisting, and extending your legs freely within the bike. Consider the pant’s cut; some are designed for a more athletic, tapered fit, while others offer a roomier profile. Pre-curved designs enhance comfort in the riding position. Ensure the pants don’t bind when you’re seated or standing on the pegs. Prioritize a fit that allows unrestricted movement, enabling you to react quickly and confidently on the track, maximizing performance and minimizing risk.
Glove Sizing
Properly fitted motocross gloves are essential for comfort, grip, and control; accurate sizing prevents blisters and ensures a secure connection with the handlebars.
Measuring Your Hand for Gloves
To determine your glove size, you’ll need a flexible measuring tape. Wrap the tape around the widest part of your hand, excluding your thumb. This is typically across the palm, just below your knuckles. Ensure the tape is snug but not overly tight – you want a comfortable measurement, not a constricting one.
Record this measurement in inches or centimeters. It’s helpful to measure both hands, as they may differ slightly. Use the larger measurement when referencing a sizing chart. Some manufacturers may also ask for your hand length, measured from the base of your palm to the tip of your longest finger.
Remember that glove sizing can vary between brands. Always consult the specific sizing chart for Thor MX or Seven MX gloves, as their measurements may differ. Consider the type of gloves you’re purchasing – thicker gloves for colder weather may require a slightly larger size to accommodate extra layers.

Seven MX emphasizes a precise fit for enhanced grip and dexterity. Many riders find Seven gloves run true to size, but if you’re between sizes, opting for the larger size is generally recommended to avoid restriction. Prioritize a comfortable, secure fit that allows for full range of motion without slippage.
Glove Sizing: Comfort and Grip
Properly sized motocross gloves are paramount for both comfort and maintaining a secure grip on the handlebars. Ill-fitting gloves can lead to blisters, hand fatigue, and reduced control, impacting performance and safety. A snug, yet not restrictive, fit is ideal, allowing for full dexterity and feel.
Consider the thickness of the glove material when selecting a size. Thicker gloves may require a slightly larger size to accommodate the added bulk. Ensure there’s enough room to comfortably bend your fingers without excessive tightness. A good test is to simulate riding – grip the handlebars and check for any pressure points or restrictions.
Prioritize gloves with features like reinforced palms and silicone grip patterns for enhanced control, especially in wet or muddy conditions. Remember, a comfortable and secure grip translates directly to improved confidence and performance on the track.
Boot Sizing
Motocross boot sizing is critical for protection and control; accurate measurements, considering sock thickness, are essential for a secure and comfortable fit during rides.
Measuring Your Foot for Boots
Accurate foot measurement is the foundation of proper motocross boot sizing. Begin by tracing your foot on a piece of paper while standing with your weight evenly distributed. Measure the length from the heel to the longest toe – often, but not always, the big toe – in both feet, as sizes can vary.
Use a ruler or measuring tape, ensuring it remains flat against the tracing. Record the measurement in inches or centimeters. It’s also beneficial to measure the width of your foot at the widest point. Wear the socks you typically wear while riding when taking these measurements.
Consider that boot sizing often differs from standard shoe sizing. Many manufacturers provide specific sizing charts based on these measurements. Don’t simply convert your shoe size; always refer to the boot manufacturer’s chart for the most accurate fit. Remember to account for potential swelling during intense riding sessions when selecting your size.
Shoe Size Chart Conversions (US, UK, EU, MX)
Understanding international shoe size conversions is vital when purchasing motocross boots, as manufacturers often utilize different sizing systems. Here’s a general guide, but always prioritize the specific chart provided by the boot brand.
Typically, US men’s sizes correlate roughly as follows: US 8 = UK 7.5 = EU 41-42 = MX 26.5-27cm. US 9 = UK 8.5 = EU 42-43 = MX 27.5-28cm. US 10 = UK 9.5 = EU 43-44 = MX 28.5-29cm. US 11 = UK 10.5 = EU 44-45 = MX 29.5-30cm. US 12 = UK 11.5 = EU 45-46 = MX 30.5-31cm.
These are approximate conversions; variations exist between brands. The MX sizing often refers to the foot length in centimeters. Women’s sizes generally require subtracting 1-1.5 sizes from the men’s equivalent. Always double-check the manufacturer’s size chart, as discrepancies can lead to an ill-fitting boot. Prioritize accurate foot measurement (as detailed previously) before consulting conversion charts.
Boot Sizing: Room for Socks
Crucially, motocross boots require sufficient space to accommodate thick MX-specific socks. These socks add considerable bulk, impacting the overall fit. Never size boots based on your barefoot measurement; always measure your foot while wearing the socks you intend to ride with.
Generally, aim for approximately 0.5 to 1 centimeter (roughly ¼ to ½ inch) of extra room at the toe of the boot. This allows for foot movement and prevents pressure points during riding. Too much room, however, can compromise control and increase the risk of blisters.
Consider sock thickness variations – some riders prefer thinner socks for warmer conditions, while others opt for thicker socks for colder weather or added cushioning. Account for the thickest socks you anticipate using when determining your boot size. A snug, secure fit is paramount, ensuring optimal performance and protection on the track.
