Cylinder Head Billet For 55mm Cranks

Product Code: 210826305


CNC machined billet cylinder head for Malossi or PM Tuning 172cc kits.

This is to be fitted when you are using the long stroke 55mm crank.

The advantage of using this cylinder head is that is it pre machined to accept the longer stroke crank so just adjusting the base gasket thickness is all you will need to do, gone are the days where you have to use unreliable packers.

Other than improved compression ratio to give extra performance it has been machined so that the spark plug is in the centre of the combustion chamber to improve burn and flame propagation. Due to this it comes with a special dedicated spark plug.

To be used with the original off centered skull cap.
