Full product description (H1: KZ FREELINE Wrap-up String Earning - Original Part Birel Art)

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:

1. 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).

2. 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.

Technical characteristics:

• 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

- 3. Tip in Michel (the corner of the expert)

* "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! "*

❓ 5. FAQ SEO (Frequently Asked Questions)

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.
