4STROKE – V4 HEAD
Monumental Achievement - Malossi
Soaring scooter performance with a power increase of 15%-25%
The first head for all Piaggio scooters that have a 4-stroke, liquid cooled engine with the following displacements: 125*cc, 180*cc, 200 cc, 250 cc, 300 cc. With more than seventy applications and designed and developed to deliver great excitement, insures this head a brilliant future.
Technical Specifications:
* This new head was developed to be used exclusively with Malossi cylinders for the displacements 125 cc – 180 cc, while with all other displacements, this new head can be used with the original cylinders. The head is pre-assembled and ready for installation.
Products reserved exclusively for racing in specifically designed locations according to the provisions of the competent sporting authorities. We disclaim all liability for improper use
Data sheet
Exhaust and Intake valve springs made of Si-Cr oil-tempered and annealed steel, designed to operate optimally under increased loads due to increased engine power.
Technical features Material: special alluminium alloy with a very high heat exchange coefficient. Geometry of heat exchange surfaces recalculated and increased. Combustion chamber completely-designed to obtain a high compression ratio with a very high turbolece. Machining: numerically controlled machines.
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.

An absolute novelty: the detail that makes the new cylinder kit even more unique! The Malossi technicians have invested a great deal of energy in creating an innovative head with unique features. CHARACTERISTICS Profiled fins to channel the flow of cooling air and to make it flow along the hottest surfaces, thus optimising the heat exchange and, consequently, the outflow of heat from the combustion chamber to prevent dangerous temperature levels from being reached. An additional lateral fin to direct as much heat as possible from the combustion chamber towards the outside of the cylinder and…
