Головка цилиндра Doppler ER1 50cc MBK 51 AC

For owners of Doppler cylinder kits (or comparable 50cc kits), we have this Doppler 50cc Cylinder Head ER1 MBK 51 AC (without decompression valve) for an unbeatable price!

Compression ratio is increased and, as a consequence, performance improved, making this cylinder head a great choice for a 50cc sports or racing cylinder. One of its strong points is the use of an O-ring gasket for sealing, which is unusual for current cylinder head models; O-ring is not included, you can find it under “Spare Parts”.

Note: Doppler 50cc Cylinder Head ER1 MBK 51 AC suppresses the original decompression system!
