CYLINDER HEAD MOTO DOPPLER ER1 FOR DERBI SENDA/GPR ->2006 EURO2 (EBE050-EBS050)

The DOPPLER cylinder head is made of aluminium. The combustion chamber is machined with a bi-hemispherical switch effect which results in better engine compression. The centrally positioned spark plug provides a better explosion and a higher pressure on the piston. The O-ring assembly provides better sealing and a more precise chamber volume. This cylinder head does not benefit from a decompressor to limit losses and leaks.
