BRK Racing 74cc Cylinder Head Derbi Variant Start

BRK Racing NEW 74cc cylinder head for Derbi Variant Start.

This high compression cylinder head from manufacturer BRK is the essential complement for the BRK Racing 74cc cylinder (reference CIL-1037-HC). It has been specifically designed to work together with this cylinder, ensuring a perfect seal and an optimal compression ratio to extract the maximum performance from the Derbi Variant Start engine.

Technically, it is a "culatín"-type cylinder head, which means that part of it is inserted inside the cylinder. This design perfectly centers the cylinder head over the cylinder and improves sealing.

Manufactured in aluminium and with a high-turbulence hemispherical combustion chamber, it guarantees fast and efficient combustion. It is important to note that this model does not have a decompressor.
