Alpinestars KMX-9 v2 Graphic 3 Kart Racing Suit
The Alpinestars KMX-9 v2 Graphic 3 Kart Racing Suit delivers certified protection, driver-focused comfort, and aggressive motorsport styling for developing and experienced kart racers. Its technical two-layer construction combines abrasion resistance with a lightweight feel, making it a dependable choice for competitive karting.
Inside, a soft polyester toweling liner helps manage moisture and improves comfort during demanding sessions. Strategically positioned mesh panels increase airflow, while knitted stretch inserts allow the suit to move naturally with the driver in the kart.
CIK-FIA Level 2 Kart Racing Protection
The KMX-9 v2 Graphic 3 is homologated to the CIK-FIA Level 2 standard N 2013-1. This certification confirms that the suit was tested for the abrasion resistance and protective performance required under that homologation standard.
Drivers should always confirm that the approval shown on the suit’s sewn-in label meets the current requirements of their track, series, or sanctioning organization.
Two-Layer Construction Without Excess Bulk
Alpinestars uses a technical two-layer assembly to balance protection, breathability, and weight. The durable twill polyamide outer shell is engineered to withstand the abrasion risks associated with kart racing, while the technical inner layers improve fit and comfort.
The suit is patterned to limit unnecessary material bunching when seated, helping the driver remain comfortable and unrestricted through steering, braking, and pedal movements.
Moisture-Wicking Polyester Toweling Liner
A 100% polyester toweling liner provides a soft interior surface and helps move moisture away from the driver. This is particularly useful during warm-weather races, long practice sessions, and back-to-back heats.
The liner also improves comfort between the driver and the suit’s protective outer construction without adding excessive stiffness.
Ventilation in High-Heat Areas
Technical mesh panels are positioned beneath the arms and around the seat and crotch areas to improve airflow where heat commonly accumulates. This targeted ventilation helps the suit remain more comfortable without compromising the main abrasion-resistant panels.
The breathable layout makes the KMX-9 v2 Graphic 3 well suited to indoor tracks, summer events, and racers who regularly complete extended sessions.
Stretch Panels for Seated Mobility
Knitted stretch panels across the back shoulder and lumbar areas allow the suit to flex as the driver reaches for the steering wheel and changes body position. Additional waist stretch helps maintain a close fit without restricting movement.
These flexible zones reduce resistance across the upper back and waist, helping the suit follow the driver rather than pulling against the body.
Pre-Shaped Karting Fit
The arms, legs, and torso use anatomically patterned panels designed around the seated karting position. This shape reduces excess fabric and improves mobility through the elbows, knees, hips, and shoulders.
Knitted wrist and ankle cuffs provide a close fit and help prevent the sleeves or pant legs from shifting while driving.
Asymmetric Front Opening
Alpinestars’ angled front opening improves entry and helps reduce material buildup through the center of the torso. The design works with a premium YKK zipper and dual-slider configuration for convenient adjustment.
Personalized zipper pullers make the closure easier to operate while wearing karting gloves.
Adjustable Waist for a Personalized Fit
An integrated waist belt allows the driver to fine-tune the fit around the midsection. A properly adjusted waist helps keep the suit positioned correctly while reducing loose fabric around the seat and torso.
Formula 1-Inspired Shoulder Details
The shoulder epaulettes draw inspiration from Alpinestars’ Formula 1 racing equipment, giving the Graphic 3 suit a professional competition appearance. Bold contrast panels and ASTARS branding complete the modern motorsport design.
Convenient Off-Track Storage
Two thigh pockets provide convenient storage when the driver is away from the kart. They can hold small paddock essentials without interfering with the suit’s driving fit.

Is this suit certified to the newer FIA 8877-2022 standard?
No. The KMX-9 v2 Graphic 3 was homologated under the earlier CIK-FIA N 2013-1 standard. Racers whose series requires FIA 8877-2022 equipment should select a suit carrying that newer approval.

It uses a technical two-layer construction designed to provide abrasion protection while keeping weight and bulk under control.
What material is used inside the suit?
The interior includes a 100% polyester toweling liner with moisture-wicking properties for improved driver comfort.
Where are the ventilation panels located?
Breathable mesh is positioned beneath the arms and around the seat and crotch areas to increase airflow in high-heat zones.
Does the suit have stretch panels?
Yes. Knitted stretch panels across the back shoulders and lumbar area improve flexibility while the driver is seated.
Is the waist adjustable?
Yes. An integrated belt allows the waist fit to be tightened and personalized.
What type of zipper does it use?
The suit uses a premium YKK zipper with two sliders and personalized zipper pullers.
Does the KMX-9 v2 Graphic 3 have pockets?
Yes. Two thigh pockets provide storage for small items while the driver is away from the kart.
Are the cuffs elasticated?
The wrists and ankles use knitted cuffs that provide a close fit and help keep the suit securely positioned.
How should a kart racing suit fit?
The suit should provide enough room to sit, bend, and reach the steering wheel without pulling tightly across the shoulders, crotch, or knees. Excessively loose material can bunch while seated.
Can this suit be used for automobile racing?
No. It is designed for kart racing and is not a substitute for a flame-resistant automobile racing suit certified to FIA 8856-2018, SFI 3.2A, or another required auto-racing standard.

Alpinestars KMX-9 v2 Graphic 4 Kart Racing Suit | CIK-FIA Level 2
$99.66
$359.95
Alpinestars KMX-9 v2 Graphic 4 Kart Racing Suit
FIA 2025 Expiry – All Sales Final
The Alpinestars KMX-9 v2 Graphic 4 Kart Racing Suit combines a lightweight two-layer build, abrasion-resistant materials, and strategically placed ventilation for drivers seeking proven Alpinestars performance at a clearance price.
Originally homologated to the CIK-FIA Level 2 N 2013-1 standard, this Graphic 4 suit features a durable twill polyamide outer shell, a soft polyester toweling liner, flexible stretch panels, and an anatomically shaped driving fit. Its bold Black/Cyan/Yellow Fluo graphics give the suit a distinctive appearance while maintaining the technical construction of the KMX-9 v2 platform.
Important 2025 Homologation Expiry Notice
This suit is part of older inventory carrying a 2025 homologation expiry. It may no longer qualify for championships, tracks, or sanctioning organizations that require an in-date karting suit or current FIA 8877-2022 approval.
Before purchasing for organized competition, confirm the equipment requirements with your race director or sanctioning body. The suit may remain appropriate for practice, recreational karting, indoor karting, driving schools, private track use, or events that do not require current homologation.
Graphic 4 Styling That Stands Apart
The Graphic 4 design uses a Black/Cyan/Yellow Fluo color combination that gives the KMX-9 v2 a high-visibility, contemporary appearance. Contrasting graphics flow across the chest, shoulders, arms, and legs, creating a coordinated design that remains recognizable from anywhere around the circuit.
Formula 1-inspired shoulder epaulettes and prominent Alpinestars branding add a professional motorsport finish without adding unnecessary weight or restricting movement.
Technical Two-Layer Construction
The KMX-9 v2 Graphic 4 uses an advanced two-layer assembly engineered to balance abrasion protection, breathability, and low weight. Its twill polyamide outer shell provides a durable barrier against the abrasion risks associated with kart racing.
Technical inner layers improve comfort and help the suit maintain its shape while the driver moves between standing, walking, and the tightly seated karting position.
Soft Polyester Toweling Interior
A 100% polyester toweling liner creates a softer interior surface against the driver’s clothing or base layer. The material offers moisture-wicking properties that help manage perspiration during warm race days and extended driving sessions.
This absorbent interior makes the suit more comfortable through repeated practice runs, qualifying sessions, and back-to-back heats.
Cooling Where Drivers Need It Most
Technical mesh panels are positioned beneath the arms and around the seat and crotch zones. These are areas where heat commonly accumulates while the driver is seated in a kart.
The targeted mesh construction encourages airflow without replacing the abrasion-resistant material in the suit’s primary protective areas.
Stretch Panels Support Seated Movement
Knitted stretch panels across the rear shoulders and lumbar region allow the suit to expand as the driver reaches toward the steering wheel. Additional flexibility around the waist helps reduce pulling across the torso and lower back.
By minimizing resistance in these areas, the KMX-9 v2 allows more natural steering, pedal operation, and upper-body movement.
Anatomically Patterned for Karting
The arms, legs, and torso are shaped around the position a driver adopts inside a kart. This anatomical paneling helps reduce excess fabric and limits material bunching behind the knees, around the hips, and across the torso.
A properly shaped karting suit can improve comfort and prevent loose material from becoming distracting during demanding sessions.
Asymmetric Front Opening
Alpinestars uses an angled front opening that helps the suit open widely for easier entry. The asymmetric layout also reduces unnecessary material concentration through the center of the torso while the driver is seated.
A premium YKK zipper incorporates two sliders and personalized pullers, allowing the closure to be adjusted conveniently in the paddock.
Personalized Waist Adjustment
An integrated adjustable waist belt allows the driver to fine-tune the fit around the midsection. Tightening the belt helps keep the torso and lower portion of the suit correctly positioned without limiting movement.
Driver Comfort Details
The ergonomic collar includes a soft knitted lining for comfortable coverage around the neck. A secure closure helps keep the collar properly positioned without creating excessive pressure.
Knitted cuffs at the wrists and ankles provide a close finish, helping prevent the sleeves and legs from shifting as the driver enters the kart or moves through a session.

Alpinestars Indoor Kart Racing Suit
$99.66
$159.95
Alpinestars Indoor Kart Racing Suit
The Alpinestars Indoor Kart Racing Suit is built for rental leagues, karting schools, recreational racing, corporate events, and indoor track sessions where comfort and durability matter. Its lightweight single-layer construction provides professional karting coverage without the weight or bulk of a multi-layer competition suit.
Durable poly-cotton twill, pre-curved sleeves, an adjustable waist, and expandable lower legs create a practical suit that is easy to wear throughout a full day at the track. Multiple storage pockets and a padded collar add convenience for drivers, instructors, mechanics, and karting facility staff.
Designed Specifically for Indoor Karting
Indoor karting demands equipment that can handle repeated use while keeping the driver comfortable in warm, enclosed facilities. The Alpinestars Indoor Kart Racing Suit focuses on mobility, convenient adjustment, and everyday durability rather than competition homologation.
It is an excellent choice for arrive-and-drive racers who want dedicated karting apparel instead of relying on ordinary clothing or track-issued rental gear.
Durable Single-Layer Construction
The suit is manufactured from a strong poly-cotton twill material engineered to resist routine wear from kart seats, harnesses, and repeated entry and exit. Its single-layer construction keeps the suit relatively lightweight and comfortable during extended sessions.
The material is patterned to reduce excess bunching around the torso and legs, helping the driver remain comfortable while seated in a compact kart cockpit.
Pre-Curved Sleeves for Steering Comfort
The sleeves are formed in a slightly bent position that follows the natural posture of the arms while holding a steering wheel. This reduces pulling around the elbows and shoulders and allows the driver to steer without fighting against the suit.
Knitted wrist cuffs provide a close finish and help prevent the sleeves from sliding or shifting during repeated steering movements.
Adjustable Waist for a Personalized Fit
An elasticated waist helps the suit conform around the midsection, while the adjustable waist belt allows the driver to tighten the fit according to preference.
Reducing loose material around the torso improves comfort in the seat and gives the suit a cleaner, more professional appearance.
Soft Padded Collar
The ergonomic collar features a soft interior lining and foam padding for improved comfort around the neck. This added cushioning is useful during longer events where an unlined collar can become irritating.
A hook-and-loop closure allows the collar to be adjusted securely without feeling overly restrictive.
Wide Calf Gussets for Easier Entry
The lower legs include wide gussets that open to provide additional room when putting the suit on over clothing or footwear. Once the suit is in place, hook-and-loop adjusters allow the leg openings to be tightened.
This expandable design makes the suit easy to use in busy rental environments where drivers may need to change quickly between sessions.
Practical Storage On and Off the Track
Two thigh pockets provide convenient storage while the driver is walking through the paddock or waiting between races. An additional interior chest pocket uses a hook-and-loop closure to secure a mobile phone or small personal item.
Items should always be removed or safely secured before driving if they could cause discomfort or interfere with movement.
Asymmetric Front Opening
Alpinestars uses an asymmetric front opening with a durable metal zipper. This design makes the suit easier to put on while giving it a distinctive motorsport appearance.
The streamlined front closure also helps reduce unnecessary material around the center of the torso while the driver is seated.
Formula 1-Inspired Shoulder Design
The contrasting shoulder epaulettes draw visual inspiration from Alpinestars’ professional motorsport apparel. Recognizable branding and clean panel construction give the suit a polished appearance suitable for individuals, teams, instructors, and track employees.

$99.66

Alpinestars KMX-3 v2 Kart Racing Suit
2025 FIA Expiry – Clearance Item – Final Sale
The Alpinestars KMX-3 v2 Kart Racing Suit was developed for drivers seeking an athletic fit, excellent mobility, and substantial airflow during demanding karting sessions. Its technical two-layer design combines a flexible polyamide outer shell with a soft polyester toweling liner, giving the driver a balance of abrasion resistance, comfort, and freedom of movement.
Large mesh panels through the underarms, sides, and seat area help release heat, while fully floating sleeves and anatomically shaped panels allow the suit to follow the driver’s body in the seated karting position. This clearance inventory carries a 2025 homologation expiry and is non-returnable.
Clearance and Homologation Notice
This KMX-3 v2 is clearance inventory carrying a 2025 CIK-FIA homologation expiry. It should not be assumed eligible for events that require current homologation or an FIA 8877-2022-approved karting suit.
Drivers should confirm the sewn-in approval label and the current equipment rules of their track, championship, or sanctioning organization before purchasing for competition.
All clearance products are final sale and cannot be returned or exchanged.
An Athletic Suit Built Around Driver Movement
The KMX-3 v2 is cut closer to the body than many traditional karting suits. Its athletic profile reduces loose fabric around the torso, shoulders, and legs while maintaining the range of motion required for steering and pedal operation.
Strategically placed stretch materials allow the suit to flex as the driver reaches forward, rotates the shoulders, and moves within the seat. This helps maintain a secure fit without making the suit feel rigid or restrictive.
Technical Two-Layer Protection
The suit uses a two-layer construction designed around the abrasion risks of kart racing. Its stretch polyamide outer shell provides durability and helps resist material bunching, while the inner lining improves comfort against the driver.
The construction was originally certified to CIK-FIA Level 2 homologation standard N 2013-1. This is a karting abrasion standard and does not make the suit flame resistant for automobile competition.
Stretch Polyamide Outer Shell
A flexible polyamide outer fabric gives the KMX-3 v2 a more responsive feel than a rigid conventional kart suit. The material moves with the driver while maintaining the strength and abrasion resistance required from a competition-oriented karting garment.
The stretch shell is particularly beneficial around the shoulders, elbows, hips, and knees, where a driver repeatedly bends and changes position.
Polyester Toweling Liner
The inner polyester toweling liner creates a soft contact surface and helps draw moisture away from the body. This improves comfort during warm race days, indoor events, and multiple sessions completed in close succession.
The liner also helps prevent the outer shell from feeling harsh against the driver’s base layer or clothing.
Extensive Mesh Ventilation
Wide technical mesh sections are positioned beneath the arms, along the sides, and around the seat area. These zones target the parts of the body where heat commonly builds while seated in a kart.
The expanded mesh layout makes the KMX-3 v2 a strong option for drivers who prioritize ventilation and frequently race in hot or humid conditions.
Fully Floating Arm Construction
Alpinestars uses floating sleeves connected with stretchable knitted material. This design allows the arms to move more independently from the torso of the suit, reducing pulling across the shoulders when the driver reaches for the steering wheel.
The floating construction supports a more natural driving posture and helps limit resistance through repeated steering inputs.
Pre-Shaped for the Karting Position
Anatomical paneling through the arms, legs, and torso is patterned around a seated driving position. The shape helps reduce excess fabric behind the knees, around the waist, and across the elbows.
This keeps the suit more stable in the kart and reduces distracting material bunching during longer sessions.
Extraction Shoulder Epaulettes
Reinforced Alpinestars shoulder epaulettes provide defined handling points that may assist track personnel when helping a driver from the kart following an incident.
They also give the suit a recognizable professional racing appearance.
Adjustable Collar and Waist
The ergonomic collar includes a soft lining and an adjustable closure that provides secure coverage around the neck without unnecessary pressure.
An adjustable waist belt allows the driver to tighten the suit through the midsection, helping control loose material and creating a more personalized fit.
YKK Double-Slider Front Zipper
A premium metal YKK zipper provides a durable front closure. Two zipper sliders allow greater flexibility when opening, closing, or adjusting the suit while standing in the paddock.
Personalized synthetic leather pullers make the zipper easier to operate while wearing gloves.
Driver-Focused Practical Details
Knitted wrist and ankle cuffs hold the sleeves and pant legs securely in place. Two thigh pockets provide storage for small personal items while the driver is away from the kart.
These practical details make the KMX-3 v2 suitable for race weekends, instruction, practice sessions, and team use.

Best Uses for the KMX-3 v2
Because this clearance suit carries a 2025 expiry, its best applications are generally those that do not mandate current homologation.

How the KMX-3 v2 Compares with the KMX-9 v2
The KMX-3 v2 offers a more athletic fit, a stretch polyamide shell, larger ventilation areas, and floating sleeves. These features give it a more flexible and performance-oriented feel.
The KMX-9 v2 is generally positioned as an entry- to intermediate-level suit with a more traditional outer shell and knitted stretch panels. Drivers prioritizing mobility and extensive airflow may prefer the KMX-3 v2.
