Charles Leclerc Kart CL Chassis – BirelArt CL30 S19 – KZ

Now at the top of Formula 1 with Ferrari, Charles Leclerc has never forgotten where his motorsport journey began: karting. From this awareness, the Charles Leclerc Kart project was born, with the aim of contributing to the development of the discipline and making it accessible and competitive for a wider audience.

To bring this project to life, it was natural for Charles to turn to BirelArt, a world-renowned Italian brand known for its manufacturing quality and technical expertise in international karting.
For Charles, BirelArt is a choice of both heart and mind.

“You must always remember where you come from. I know what I owe to karting: everything. It’s where my passion for motorsport was born, where I learned the fundamentals that allowed me to reach the top, and where I met some of the most important people who supported me along the way. I had been determined to do something for karting for a long time, and now is the right moment.”

BirelArt’s technical capabilities have also been confirmed by major sporting achievements, including a prestigious one-two finish at the KZ World Championship in Lonato, further reinforcing the goal of creating a chassis bearing the Charles Leclerc name capable of performing at the highest level in all conditions. Only a major manufacturer like BirelArt can guarantee such high production quality on a large scale.

Technical evolution and development

Following a very successful racing season and highly positive feedback from importers and customers worldwide, further development work was carried out on karts and accessories. In parallel with the new CIK-FIA homologations, new products were introduced within the BirelArt – Free Line range, while retaining the excellent technical base of the S18-B models.

Braking system

For KZ category chassis, the CL30 S19 is equipped as standard with the new I25x2 RR EVO front brake system, featuring:
✔ increased braking power
✔ improved overall balance
✔ enhanced and more consistent braking performance

CL30 S19 – New homologation

The CL30 S19 has been specifically developed for KZ gearbox categories. Compared to previous versions, the chassis has undergone significant structural, geometric and material updates, making it even more versatile and capable of delivering high performance across a wide range of track conditions.

• Brake balance: the new brake adjusts facilitates the adjustment of the distribution and improves its functioning.

• Rear hubs d.50: The new Freeline hubs HQ have the double fixing screw with a better axle grips in order to maintain a perfect assilaity and avoid the movement.
  
  
  

• Spindles OK - KZ: the new spindles have a lever geometry slightly different to a better entry corner. It’s also it’s also allows a better regulation on high of the frame. It will be the same for both categories with the addition to an aluminum caliper support on the KZ.
  
• Pods AERO: to reduce cantilever weights, improve the aerodynamic efficiency and a new look, were studies and developed the new Freeline side pods mod. AERO, homologation 007-BS-20.
  
• The karts models DD and SH will be equipped with new front pod and new panel developed and homologated by KG 509

• New HI TECH bushing: a new bushing has been developed and tested for caster and camber adjustment in a single component.
  This bushing allows to increase or decrease the caster by approximately ±4 degrees and to adjust camber from positive to negative by about 12/14 mm.
  These adjustments can be carried out from the upper part of the stub axle “C” (it will no longer be necessary to use eccentrics in the lower part of the “C”), in a very simple and quick way.

• HI TECH steering column: new steering column with 10 mm bearing
