The fREELINE Category KZ String is an official security piece of origin manufacturer (Original Freeline / Birel Art). It is specially designed to surround the chain transmission of Karts equipped with 125 cc gearbox motors (TM Motor, Vortex, Iame, Modena Engines).
In KZ category, rotational speeds and string voltages are extreme. This enveloping crankcase fills two essential functions:
The driver safety: It forms a robust shield that prevents hot grease projections on the driver's combination or back. In case of high speed chain case (more than 15,000 rpm), it retains the chain to prevent it from injuring the driver or damage the peripheral accessories (exhaust jar, radiator, hoses).
Technical compliance: Its ultra-protective design scrupulously meets the safety requirements of the CIK-FIA's national and international regulations.
Made in a high black density technical plastic, it is both ultra-light and extremely flexible to absorb the constant vibrations of the 50 mm back shaft without cracking.
Chassis compatibility: Birel Art, CL Kart (Charles Leclerc), Ricciardo Kart, Kubica, LGK
Category: KZ / KZ2 (gearbox motors)
Material: Polymer injected high performance hydrocarbon resistant and impacts
Design: Optimized enveloping shape for not interfering with the rear brake caliper or the exhaust pot
* "Hi the artists of the gearbox! In kz, the stringwind is subjected to tade due to the vibrations of the shaft of 50 and the direct proximity of the exhaust pot heating very strong.
My trick for a time mounted in time: neverck Never the plastic chain worm directly against your metal fastening tabs without rubber washers (silentblocs). If you tighten the hard plastic against dry metal, 15,000-turn motor vibrations will end up cracking the housing around screw holes in less than two race weekends.
Drag a small rubber washer on each side of the plastic before putting your screw and your self-fired nut (nylstop). The crankcase will have the flexibility necessary to cash the chassis work. And last tip: after each round, pass a quick cloth stroke inside to remove the excess of accumulated chain grease. It avoids that the crankcase breaks up and vanish against the crown! "*
Place the kart on his carriage. To have perfect access to the right transmission, remove the right rear wheel (engine side) and the side body panel if necessary.
Present the FREELINE stringholder above the Crown / String assembly. Verify that there is a sufficient safety space (at least 1 to 2 cm) all around the crown to avoid friction when the Flex Flex chassis.
Align the anchor points with the chain carrier attached to the chassis. Apply the trick to Michel: Insert rubber washers to dampen the vibrations, then pass your screws.
Tighten the nuts firmly but progressive, without completely crushing silentblocks. Launch the hand-in-white backtrall: the chain and the crown must rotate perfectly free without touching the plastic crankcase at any time.
Q: Is this string-compatible handwright with a monowned kart (Rotax Max, Iame X30, OK) ?
A: Not. On a monovite kart, the engine is located closer to the seat and the alignment of the chain is different. KART KARTS have the offset engine and the transmission requires this specific enveloping form. For categories without box, opt for light standards string models (open or semi-open).
Q: Does this freeline housing adapt on a chassis of another brand (ex: Tony Kart, CRG) ?
A: Yes, the chain's barrier itself can adapt to other KART brands KAZ, because the arrangement of the crown and chain remains substantially identical to one kz to another. However, you will need to ensure that your chassis attachment legs are compatible or adjustable with the centerpiece of this crankcase.
Q: Does the kit include metal fastening legs at the chassis ?
A: No, this product includes the freelated black plastic housing alone. Welded or screwed metal brackets at the chassis tube are part of the frame accessories and are sold separately if your chassis is not already equipped.
The Iame X30 pinion Origin is designed to equip X30 engines by ensuring reliable and efficient transmission. Using accurately, it provides optimal haling with the chain and perfect compatibility with the original configurations.
His assembly is done with 4 screwsensuring secure attachment on the motor axis.
Optimize the behavior of your competition karting with the rear rim OTK AXJ aluminum.
Specially designed for categories Mini (minimal / cadet), This 145 mm width rim is the standard model equipping the chassis of the group OTK (Tony Kart, Kosmic, Exprit, etc.). Made of high quality aluminum, It offers an ideal compromise between rigidity, lightness and thermal dissipation, crucial for the performance of tires on dry track as wet.
TheIame x30 14 × 44 mm piston axis is one Original Iame motor partspecially designed for karting engines X30. It guarantees precise adjustment, optimum reliability and perfect compatibility with engine specifications.
This element is essential for the proper functioning of the piston / rod assembly and contributes directly to the longevity and engine performance.
The OTK 50 mm 180x13 Magnesium - BWD brake disc holder, new 2025, is an essential part for chassis from the OTK group, including Tony Kart, Kosmic, Exprit, Carlos Sainz, EOS, and Red Speed. Here's some more information on this product:
The Kit of 3 water hose x30 marked iame is a Original manufacturer accessory, specially designed for IME X30 engines (125cc, Super 175cc, and other variants). This kit is indispensable to ensure a optimal cooling engine, guaranteeing constant performance and an maximum reliability in competition as in training.
Made in High quality materials, these hoses are Resistant heat, pressure and cooling fluids, and are marked iame for a Authenticity and perfect compatibility with the cooling systems of the X30 engines. The kit includes three hoses and the Required clamps For a quick and secure installation.
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.
The Valve box cover (or intake conveyor) of 29 mm is the major technical evolution of the X30 engines since 2018. Located between the carburetor and the pyramid of valves, its role is to "guide" the vein gas aerodynamically. Its 29 mm inner conduit is perfectly aligned with the new carburetors, eliminating turbulence for more frank acceleration and maximum engine fill.
