Chassis BirelArt RY 30-S19 - SH - KZ 2026!

Based on the S18 models, like every year we worked during the racing season to further develop and implement the performances of our karts, modifying geometries, the materials and some accessories, introducing new details to always have a better product both on quality level and on performance, confirmed once again by the numerous successes that we had during the season.

All BirelART karts will keep the same homologation number for the new period, as made an homologation extension. We will introduce new pods Free Line model “AERO” and “AERO Mini” newly homologation.

• King pin d.10
• New brake balance
• New rear hubs with double fixing L.100
• New side pods Free Line “AERO” (Homologation CIK 007-BS-20)
• New front pods and panel KG 509

FRAME AVAILABLE IN STANDARD VERSION AND “PA”

• 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
