FR-125 KZ

FR-125 KZ

1. FR-125 KZ chassis is designed and manufactured according to shifter categories standards, using 30mm chrome-molybdenum steel tubes, offering high strength and resistance to deformation.

2. Utilizes automated TIG welding technology to minimize manual errors, enhancing welding precision and quality.

3. The frame undergoes primary heat treatment, significantly reducing material stress and preventing chassis deformation.

4. In the shifter category, the braking system plays a decisive role in performance. The Ibox 9 braking system (an upgraded version of the Ibox 8) is adopted for this model. This solutions provide unique heat dissipation effects for the pump and calipers, reducing brake oil temperatures. The rear brake caliper is forged in a single piece with two pistons featuring stroke recovery. It includes a 180*16 mm hydraulic floating brake disc (carbon ceramic brake discs optional). Additionally, the new brake distributor has been optimized for efficiency, and the front calipers are redesigned with enhanced fin geometry and thickness to improve heat dissipation and structural rigidity.

5. 50*2.5*1045 mm rear axle, paired with CNC-machined magnesium alloy axle hubs.

6. Lightweight design: The chassis extensively uses magnesium alloy and aluminum alloy components, including pedals, axle hubs, wheel rims, steering wheel and sprocket carrier.

7. Front torsion bar allows drivers to adjust chassis stiffness according to track conditions.

8. It features the new B11 Body Kit with a unique aerodynamic design to reduce drag and enhance on-track performance.

Hydralic Rear Brake

In the shifter category, the braking system plays a decisive role in performance. The Ibox 9 braking system (an upgraded version of the Ibox 8) is adopted for this model. This solutions provide unique heat dissipation effects for the pump and calipers, reducing brake oil temperatures. The rear brake caliper is forged in a single piece with two pistons featuring stroke recovery. It includes a 180*16 mm hydraulic floating brake disc (carbon ceramic brake discs optional).

Front Brake System

Front Brake System

Completely renewed front calipers, both in the forged and machined components, showing a new design of fins and thickness, with the aim of further increasing heat dissipation capacity and structural rigidity.

Magnesium Wheel Rims

Magnesium Wheel Rims

Equiped with 130/212 mm magnesium wheel rims

Steering Wheel

Steering Wheel

To achieve a lightweight design, the steering wheel is constructed from magnesium material, wrapped in PU leather. Adjustable steering base allowing drivers to customize its position according to their driving habits.

Steering geometry

Steering geometry

Spindles with cast stainless steel body, with flange and removable wheel axle by means of a fixing bolt. Steering tie rods made from aluminium material with aluminium bushes to fix uniball. eccentric adjuster allow driver to choose the most suitable setup, according to use (indoor track, outdoor track, short, quick, mixed...). Each front wheel is mounted on four bearings to reduce axle loads as much as possible.

Seat

Seat

The seat is made from carbon fiber, mounted to a steel frame on chassis

Axle Hubs

Axle Hubs

Magnesium axle hubs are adopted to improve performance and reduce weight.
