44 mm cylinder head with M12x1.5 mm decompression hole, compatible with the 44 mm swiing® tuning cylinder kit for the Zündapp Belmondo moped / mopeds with chassis number 71 and engine type 247, as well as the Zündapp M25 and M50 Bergsteiger mopeds with chassis number 434 and engine type 247.
In addition to these models, the racing kit also fits ALPA Spezial 3000 or ALPA Black River small motorcycles equipped with a Zündapp Type 247 engine.
The shoulder on the gasket side ensures that the cylinder head sits perfectly centered on the cylinder.
Note: If you want to install this cylinder head on an original Zündapp cylinder, you must raise it by 1.5 mm to prevent the piston from rubbing against the head.
Also note that, due to the design, you will need longer stud bolts.
You can find the stud bolts mentioned above, as well as the complete cylinder kit, in the accessories section.
