Like every year, we present the new developments of the 2025 season that will be introduced in the Birelart – Freeline karts and products for the 2026 season.

The acronym that characterizes the new models for 2026 will be S19.

Starting from the S18 models, also for this racing season we have conducted an important development activity aimed at optimizing the overall performance of the kart.
The intervention has involved the evolution of the frame geometry, using new materials with improved mechanical characteristics and revising of some accessory components.
New technical details have also been introduced, projected to increase the products dynamic efficiently and construction quality of the products. The results obtained on track, both nationally and internationally, confirm the validity of the work made.

CHASSIS MOD. RY30 SH Hom.007/CH/10 & RY32 Hom.007/CH/12

As for the DD karts, also for the shifter categories (SH) different types of frames have been defined to cover all the different characteristics found with different types of tires and tracks in the various national and international championships.
Unlike the single-gear, the frames vary not only in materials but also in geometry.
The acronyms of the various are printed inside the tank fixing plate
The steering column uniball sit has been modified to accommodate a more resistant 10mm diameter ball joint

• RY30 S19 standard: base model S18
• RY30 S19 type “PA”: frame std with “special” support axle bearing (more grip)
• RY30 S19 type “PA2”: frame softer with “special” support axle bearing
• RY30 S19 type “6”: frame more rigid ideal with standard support axle bearing
• RY32 S19 standard : base model S18
• RY32 S19 type “PA”: frame std with “special” support axle bearing (more grip) 
    

 NEW FREELINE PARTS 

• NEW GRAPHIC: like every year we revised the graphic try to give an always more aggressive, modern, and recognizable look that distinguishes the BirelART brand.
  It will be standard on all Birelart DD, SH, DD2 & MINI models.

• NEW BUSHING HI TECH: A new one-piece caster and camber adjustment bushing has been developed and tested. This will be able to increase or decrease caster by plus or minus 4 degrees and adjust camber from positive to negative by approximately 12/14 mm.

  Will be possible to make these adjustments from the top of the "C" stub axle (it will no longer be necessary to use eccentrics at the bottom of the "C") very quickly and easily.
  It will be mounted as standard on DD, SH, and DD2 karts.

• STEERING COLUMN HIT TECH: new steering column with 10mm bearing
