OMP KS-4 Karting Suit – CIK-FIA Level 1 (2026 Expiry)
The OMP KS-4 Karting Suit is a value-focused choice for kart racers who need durable abrasion protection, breathable comfort, and dependable freedom of movement. This closeout model features four-layer construction and CIK-FIA Level 1 homologation with a 2026 expiry, making it an affordable option for eligible racing series, practice sessions, and recreational karting.
A resistant polyester exterior helps protect the driver from abrasion, while the soft cotton-sponge interior improves comfort during long sessions. Ventilated mesh inserts and flexible arm bellows help reduce restriction and heat buildup when driving in a seated karting position.
Four-Layer Karting Protection at a Closeout Price
The KS-4 uses a four-layer construction designed specifically for kart racing. Its durable polyester outer material provides abrasion resistance, while the soft interior creates a more comfortable surface against the driver’s clothing or karting base layers.
This is not a flame-resistant auto racing suit. It is purpose-built for karting, where protection from contact with the track surface is the primary concern.
CIK-FIA Level 1 Homologation
This version of the OMP KS-4 is homologated to the CIK-FIA Level 1 karting standard and carries a 2026 expiry. Because individual championships may require newer FIA 8877-2022 equipment, drivers should confirm the accepted suit standard with their track or sanctioning organization before purchasing.
The certification label sewn into the individual suit should always be treated as the final reference for its homologation and expiration information.
Breathable Construction for Hot Karting Sessions
OMP places ventilated mesh inserts around the legs, shoulders, and pocket areas to improve airflow through common heat zones. These breathable sections help make the KS-4 more comfortable during indoor karting, warm-weather practice sessions, and extended race weekends.
The low-cut collar also reduces excess material around the neck when seated, helping the driver remain comfortable while wearing a helmet and neck support.
Flexible Fit Behind the Wheel
Elastic knitted arm bellows allow the sleeves to move more naturally as the driver steers through tight corners. The kart-specific fit reduces restriction across the shoulders and upper body, while the adjustable waist belt helps create a secure and personalized fit.
The straightforward design makes the KS-4 especially suitable for newer racers, budget-conscious competitors, rental-kart league drivers, and experienced drivers looking for a dependable backup suit.

OMP KS-4 Karting Suit FAQs
What does the 2026 expiry mean?
The suit’s CIK-FIA Level 1 homologation is marked with a 2026 expiration. Acceptance can still vary by championship, so confirm the required standard with your track or racing organization before ordering.
Can I use the OMP KS-4 in FIA-sanctioned kart racing?
That depends on the event regulations. Some organizations may continue accepting CIK-FIA Level 1 suits through their labeled expiration, while other series now require FIA 8877-2022 homologation.
Is this the new OMP KS-4 MY2026 suit?
No. This is the previous four-layer KS-4 model with CIK-FIA Level 1 homologation. The redesigned MY2026 version has a different product number, material package, ventilation system, and overall construction.
Is the OMP KS-4 fire resistant?
No. The KS-4 is an abrasion-resistant karting suit and is not designed to provide flame protection. It must not replace an FIA- or SFI-certified fire-resistant suit in automotive racing.
How many layers does this KS-4 have?
This previous-generation OMP KS-4 uses four-layer construction. That specification applies to the CIK-FIA Level 1 version shown in this listing and not necessarily to newer suits carrying the same KS-4 name.
Where are the ventilation panels located?
Mesh inserts are positioned around the legs, shoulders, and pocket areas to increase airflow and help reduce heat buildup during karting sessions.
Does the KS-4 provide good arm movement?
Yes. Elastic knitted bellows around the arms help the sleeves move with the driver while steering, reducing pulling and restriction across the shoulders.
Is the OMP KS-4 suitable for indoor karting?
Yes. Its abrasion-resistant construction, ventilation panels, and comfortable interior make it suitable for indoor karting leagues and practice sessions, subject to the facility’s clothing requirements.
Should I size up when wearing a rib protector?
Take your measurements while accounting for any rib protector or protective gear worn underneath the suit. When measurements fall between sizes, the larger option will usually provide more room while seated.
How should I wash the OMP KS-4?
Follow the care label attached to the suit. Use a mild detergent and cool, gentle wash when permitted. Avoid bleach and fabric softener, and allow the suit to air dry rather than using high heat.
Can closeout karting suits be returned?
Return eligibility depends on Competition Karting’s current closeout policy. Keep the suit clean, unused, and fully tagged until the fit and certification have been confirmed.
