Cylinder head DOPPLER ER1 Ø40mm high air compression without decompressor Peugeot 103 / fox / wallaroo

The DOPPLER ER1 cylinder head is a very good racing cylinder head, it can be mounted on all 50cc air kits on the market for Peugeot 103, Peugeot fox and Honda wallaroo although it is perfectly suited to the high DOPPLER ER1 engine and other models.

It is also mounted on the high original engines. This model has a high compression frustoconical combustion chamber. It does not have thread to install a decompressor.

It is of very good quality, it will offer you more performance and better cooling than an original cylinder head and it has a location for engine numbering. Please note that the squish zone is not at zero and the cylinder head is delivered bare, without cylinder head gaskets. Like the PARMAKIT, you can install an O-ring or standard. The finish is really excellent.
