List of products by brand BIREL
The tank is screwed into the body of the pump. Between these two rooms is an O-ring (O-Ring) or a sealing washer that does all the work.
The role of fixing: Hold the tank integral with the pump while ensuring perfect sealing to prevent air from being sucked into the circuit during the pumping phase.
Fragility: The tank threaded tip is often plastic. If you force too much, you risk breaking plastic in The body of the pump (very difficult to extract).
Secure the front train from your machine with theSpecial Rocket Nut Original Builder Birelart (Original Birelart Genuine Parts). This specific nut is the official spare part to ensure the locker lock and maintenance of front hubs or front rims (depending on your configuration) on the threaded axis of your rockets.
Machined according to an ultra-strict specification by the Italian plant, this nut differs from standard models of trade by its specific screw and flange or its integrated mechanical braking system adapted to the extreme constraints of competition karting. Subjected to constant vibrations, to violent load transfers during braking and high-speed curve, it ensures that no mechanical game is created on the front axle, thus preserving the surgical accuracy of the train of your train. Red chassis.
This high-end adjustable pedal system, machined in the mass (Ticket), is a piece of technical gold from the competition department ofBirel ART. It allows to adjust the distance of the pedals with millimetre precision thanks to a sliding support anchored directly on the steering column support.
This is the ultimate solution to ensure an ergonomic driving position, better braking control and more precise acceleration without having to change the frame.
This Front brake caliper support for KZ (gearbox) category is a high precision mechanical part of origin manufacturer (Original Birel Art). It is specifically developed to adapt to the latest generation of Rockets appeared on the 2025 range.
CNC machined in a block of aeronautical quality metal with a black anodized finish, this support ensures the critical and rigid connection between your front rocket and the brake caliper. In Kz, the front braking system undergoes colossal pressures. This support is dimensioned to eliminate any mechanical twist during violent braking, ensuring a Perfect alignment of the pads on the disc and an ultra-precise feeling at the pedal.
The FREELINE BRAKE CUP (dimensions 25 x 30 x 2 mm) is a high precision replacement hydraulic component of origin manufacturer (Original Freeline / Birel Art). It is designed to ensure absolute internal sealing and pressurizing the circuit at the cylinder master piston on the group's competition chassis Birel Art.
This cup (or specific lip seal) displays an inside diameter of 25 mman outside diameter of 30 mm and a thickness / height of 2 mm. Its technical profile is specially molded to evade under the pressure of the brake fluid, ensuring that no internal leakage occurs when the driver crushes the pedal. Made in a high-end elastomer resistant to chemical aggressions of competitive fluids, it maintains a reactivity of instantaneous and constant pedal, handle after handle.
