Description
Modular cylinder head Voca Race Head
VOCA Race Head - 2-piece cylinder head with removable combustion chamber 50mm for Minarelli AM6. The head is part of the Voca Bestia 80cc cylinder kit.
Tuning cylinder head Voca Race Head
This two-piece, modular head consists of a water jacket made of anodized aluminium and a removable combustion chamber including O-rings.
Cylinder head:
The CNC-milled head is designed for 50mm pistons with original stroke. It has a locking pin that prevents the cylinder head from twisting when the spark plug is tightened or loosened. The optimum squish value is 0.8.
Cooling has been improved to allow for higher outputs.
Temperature sensor:
The thread allows the original temperature sensor to be used. Aftermarket sensors are also available for use with digital instruments, e.g. temperature sensors from Koso and Stage6.
Gaskets:
Another important feature is the replacement of the original single head gasket with O-rings. They ensure better sealing and reliability.

Cylinder head
The cylinder head of an internal combustion engine can have different shapes and contain different elements, depending on the type of engine. While in a two-stroke engine the cylinder head contains only the spark plug, in a four-stroke engine it is much more complex, as it also contains the valves, the camshaft and many other parts that are important for the operation of a 4-stroke engine.
However, these two points apply to any cylinder head:
- it must be tight
- it controls compression
Different types of cylinder heads
Each cylinder head is specifically designed for a specific cylinder. You must therefore always make sure that the cylinder head fits the cylinder.
Cooling :
The cylinder head is also partially responsible for cooling the engine. In air-cooled engines it has fins on the outside and in liquid-cooled engines there is chamber for the circulating coolant.
One-piece or two-piece 2-stroke cylinder head
One-piece cylinder heads are the most common, but modular two-piece cylinder heads are also available for 2-stroke engines. The principle is quite simple: the water jacket allows water circulation, while the combustion chamber insert closes off the combustion chamber. The cylinder head can be replaced and modified to achieve different compression ratios and thus different engine behavior.
4-stroke cylinder head
Tuning cylinder heads can also be found for four-stroke engines. Although components optimized for motocross are seldom found on the market (usually they are original components that have been reconditioned to increase performance), there are also racing cylinder heads for scooters and motorcycles. These often have optimized intake and exhaust ports and sometimes even seats for larger valves.
