The head is designed to enter the cylinder?s combustion chamber, safeguarding the nickel coating in case of detonation.

In order to install V4 HEAD on Piaggio engines 125 - 250 ie 4T LC produced as from September 2014 and featuring roller rocker arms in the cylinder head, you need to buy Malossi camshaft (Code = 5911962), besides PIAGGIO products.

Technical features Another revolution in the construction philosophy of two-stroke engines: the cooling fins have been dimensioned to optimise the heat flow from the chamber to the outside, but now are also shaped, based on modern simulations to allow maximum penetration of the air coming from the cooling system, which now touches the head with a 10 % plus increase in performance compared to a traditional system with straight fins. The characteristic hemispherical combustion chamber is machined with tolerances to the tenth of a millimetre and produces a high turbulent combustion, with…

H.T.S.R. HEAD (High Turbolence Squish Racing) Heads with high turbolence concentric combustion chamber, squish set during the dynamometrical brake adjusting, re-calculated linings and cooling surfaces, made of high silicon content aluminium, pressure melted, worked on highest precision working centres, with anti-detonating and anti-oxidationtreatment on the surface.
