The nylon axis OTKis the next generation connecting part for your side pontoons. Unlike old pin models, this axis uses an extended flat head and an adjusted body for optimal friction support. This system allows faster disassembly and offers controlled flexibility that protects your chassis during lateral contacts.
Make: OTK (Origin Tony Kart).
.Material: High resilience technical Nylon.
Available colors: Red (photo) or Black.
Type: Without pin (fixation per stop head and tight fit).
Compatibility: Recent group chassis OTK (Tony Kart, Kosmic, Exprit, Redspeed, Gillard, EOS).
Magickart Loyalty Program: By choosing original parts OTK, you collect loyalty points on your future consumables.
"The absence of pins on this model is not an oversight, it is a desire to KG and OTK simplify the bodywork. My expert advice: The axis must enter 'gras' into the support. If it slides too freely, the pontoon support (the tube) is slightly open or the axis is worn out.
Essentials with your nylon axes (n°4934.jpg):
Bridge supports OTK : Check that they are not twisted, because a bad alignment would 'work' the cross axis and eventually eject it.
Side pontoons M6/M7/M10: Make sure the pontoon's eye is not ovalized.
A little pro secret: If you're afraid of losing the axis on a very bumpy track, a simple tape trick (Chatterton) on the head of the axis is enough to reassure the most concerned. But normally, adjustment OTK is perfect! At Magickart, we love this model because it does not scratch the chassis and installs in two seconds."
Cleaning: Before inserting, take a rag inside the pontoon holder to remove gum and dust.
Installation: Insert the axis firmly until the flat head stops against the pontoon.
Control: Pull slightly on the pontoon to check the resistance. The axis must not go up on its own.
Interview: If the axis becomes whitish or has deep marks, change it. Nylon loses its elastic properties over time and UV.
Perfect fit: Only the original axis meets the exact rating at the tenth of a millimetre to hold without pins.
Look Factory: Red OTK Stay alive and do not tarnish from the first exit.
Immediate availability: We know that these axes are the first victims of enlivened departures, we still have them in stock.

The Circlip Birelart is a critical safety piece for your braking system. Its role is to lock the axis that crosses the brake pads inside the stirrup. Without it, the intense vibrations of karting could slide the axis, resulting in the loss of the pads and a total braking failure.
Made of high quality spring steel, this "wire" circlip has a calibrated voltage to stay lodged in the throat of the axis, even under the most severe constraints encountered in competition.
The steering column is the direct link in your hands and the front kart train. This version 2021 of 490mm is specifically designed for the Birelart chassis geometries of this generation. Being delivered "naked", it allows you to go up your existing accessories (steering wheel hub, ball joint, column holder) or customize your unnecessary toll-free mounting on parts that you already owned

The Thunder-end needle cage (often referenced under the norm Hk1010, Ref. Rotax 232460) is a small needle bearing housed in the engine housing or launcher support. It receives the end of the electric starter shaft. Its role is crucial: it allows the tree to rotate at very high speed during the start phase with a minimum of friction, while supporting the radial stresses during the haling.
Complete Kit Bumper Mounting AR - Rookie - Mini OTK
Guarantee the thermal tightness and absolute reliability of your high engine with the Cylinder head O-ring of small diameter of origin iame, specially designed for the karting engine IME X30 (referenced in Figure 16 on the official burst).
Earning of Manufacturer (OEM), this O-ring ensures a perfect barrier against combustion pressures and coolant flows, thus avoiding any leakage or overheating on the track.
THE'AGIP oil ENI 2T is a high-end synthetic lubricant specially formulated for two-stroke karting engines. Used in the Vortex Rok Cup, this oil meets the strictest performance and protection requirements.
This m6x20 hollow hollow screw header is a spare part of origin OTK, Designed for use on competition karts. It is made of high quality steel for exceptional resistance and durability, and has a zincped finish for corrosion protection. The milled head allows the screw to flush the surface, offering a clean and aerodynamic finish. The hollow six-flap impression allows easy tightening and loosening with a standard Allen key.
The piston with original band Rotax is an essential component for engines Rotaxdesigned to provide optimal performance and exceptional durability. This piston is suitable for multiple engine models Rotax, including the Rotax Micro max, Rotax Mini max, Rotax Junior, and Rotax Max (senior). Fabricated Rotax, a brand recognized for its quality and innovation in the karting world, this piston is ideal for demanding drivers looking for reliable and efficient solutions for their karting engines. In addition, Magickart offers this piston at a more competitive price than that of French and Italian competition, allowing you to benefit from the best quality at the best price.

The CRG Kt2 is the versatile chassis par excellence of the Italian manufacturer. Unlike the Rébec Road (more rigid), the KT2 uses a frame compound full of tubes of 30 mm in diameter. This architecture offers controlled flexibility, ideal for freeing the engine in categories without gearbox like the OK, Iame X30 or the Rotax Max.
Its geometry allows fast adaptation to all track conditions (high grip or green track "). Featuring the last components of the range CRG RacingHe combines exceptional motor skills at a surgical front train accuracy.
The CRG KT2 2026 Version Kz redefines the standards of the Queen category. While the Road Rebel (32mm) remains the choice for the tracks with very high grip, the KT2 in 30mm Has become the favorite weapon of Kz pilots looking for more agility and ease in the support changes.
For 2026, CRG Reworked the composition of chrome-molybdenum steel to provide a better response from the front train during degressive braking. This KZ version stands out for its localized structural reinforcements and its integral front / rear braking system, essential to stop the power of 50 horsepower engines
The hub of 35 mm long is considered a "short hub". In karting, The choice of hub length is a fundamental adjustment tool:
Short hub (35 mm): It offers less contact surface with the axle than models of 75 or 90 mm. This usually allows to have a "freer" behavior of the rear train, Helping the chassis to be free from curve, Ideal on tracks with a lot of grip (adhesion).
The hub of 40 mm long is often considered the "standard" or "versatile" value on adult karts equipped with a 30 mm (x30, axle, Rotax, Kz, ok). Unlike very long (75-90mm) hubs that considerably rigidify the rear, or the very short (35mm) that fully freed the chassis, the 40 mm Offers neutral and healthy behavior, ideal for starting a setting session before refining.
The hub of 85 mm is a "long" adjustment room. In karting, the choice of the hub length is directly related to the leverage exercised on the axle:
Stability and Grip: With 85 mm, you increase the rigidity of the rear train and removing the load outward. This is the ideal tool for more moving output output or to expand your back path without stacking spacers (which weakens the assembly).
R2.0 version: This name indicates an evolution of design at CRG (best machining, optimized weight and anodized finish "Gold" for higher resistance to corrosion).
