ITALKIT competition cylinder head for ITALKIT 125cc cylinder of ROTAX 122 and 123

ITALKIT competition cylinder head stud CNC machined in high quality AL 7075-T6 aluminum in Spain. The high compression type chamber is semi-hemispherical in shape for maximum performance. The heat exchange is also better for better cooling and therefore, more performance! Arises with the ITALKIT 125cc cylinders or the original cylinders prepared with racing piston!

-For a 1.15mm squish, you will have a chamber volume of 9.75cc excluding the spark plug thread, i.e. a compression ratio of 13.76: 1 (0.30mm base gasket) "torque-type setting"

-For a 1.35mm squish, you will have a chamber volume of 13.2cc excluding the spark plug thread, i.e. a compression ratio of 13.20: 1 (0.50mm base gasket) "high speed setting / point"

To calculate the volume with the spark plug thread, add 2cc!

Recommended cylinder head gasket Ø64mm X 2mm and Ø23 X 2.5mm like the original, to be installed with the original cylinder head cover!
