First-class racing kit with 64 cc displacement – the preferred choice of many racers with Puch mopeds / mopeds.
The cylinder fits your Maxi with E50 engine or X30 Sport with Z50 engine, among others.
In combination with the supplied 2-valve reed valve system, the racing cylinder will give you plenty of torque even from low revs. Thanks to the use of a single piston ring, the tuning cylinder is also extremely high revving and aggressive. The performance often exceeds that of 45 mm cylinder heads. The workmanship is high quality and the nickel-silicon carbide coating (colloquially known as Nikasil) ensures durability and longevity.
In addition to the cylinder head, the scope of delivery also includes the piston, clips, bolts and a piston ring. The base and head gasket and the complete diaphragm system are also included.
