RY28-S9 Homologation 32/CH/20
The RY28-S9 is inspired by its predecessor, with many championships wins all over the globe. The new front end (FL F1) gives an aggressive look without losing the elegance that distinguishes the Birel ART image.
The design of the spoiler was done through a CFD study to optimize its performance and aerodynamic efficiency. This chassis is very popular for the Jr classes or the KA100 Jr/Sr.

Wheels: In 2018, we introduce our new magnesium wheels (Mod. DM 130 + 210) "LPC" (Low Pressure Cast), manufactured with a particular fusion technology. The size will be different, especially in the rear with a wider total width and an off-set of 10mm.
Front bumper: New FREELINE F1 front bumper will be mounted as series on all the "Racing" karts. It was studied and tested by CFD to improve air flow around the kart and driver allowing better brake cooling and reducing turbulence near the engine. On top of that, it gives an innovative and aggressive look.
Rear bumper: The S9 karts will come with the new rear KG CLOB model bumper.
Graphics: The sticker kit is updated for the new front pod "F1". It will also have a little "refresh" but without losing the aggressive and elegance look that distinguishes Birel ART's image.
Brake system: The brake system remains the reliable FL01 caliper with a cast iron brake disc D.180 to improve braking and reduce wear.
Spindles: Spindle stays the classic 2 piece with the choice of 5 spindle stems giving the possibility to add or remove grip on the front of the chassis.
Rear Axle: We have introduced the new R rear axle which offers a very good lateral grip, good stability under braking and optimal traction while leaving the kart very free. The rear axles are now specifically produced for KF category with only 4 keys to prevent a weakness where the KZ keyway was.
Magnesium: Front and rear hubs are available in magnesium. Fully machined rear short hubs d.40x100 mm or long d.50x115 mm double screw. Front hubs are 85mm long.
