CYLINDER KIT MHR
TECHNICAL FEATURES
CYLINDER
- Material: special aluminium alloy with high percentage of silicon and titanium that guarantees exceptional strain strength even at high temperatures.
- Heat treatment: special quenching and stabilizing treatment that gives the material increased toughness and strength, guaranteeing that mechanical and size specifications will remain unaltered for temperatures of up to 250 °C.
- Chip-forming machining: carried out on NC machining centres with extremely-limited size and shape tolerance (roundness, perpendicularity).
- Inner surface coating: effected using silicon carbide on a nickel matrix with heat treatment that guarantees extreme hardness (around 600 HVO, 1/5) and excellent resistance to wear.
- Internal machining of cylinder: using special machines that allow a degree of finish on the cylinder barrel walls whose roughness corresponds with the angles set at the design stage (grinding process using special stone).
- Port and exhaust diagrams: designed and manufactured especially for racing. The definition of the port and exhaust diagrams has requested considerable effort on the part of our engineers both on engine test stands and the circuits on which the trophy is held.
PISTON
- Material: special aluminium alloy with a very high percentage of silicon and titanium that guarantees both excellent heat resistance and strain strength upon temperature variation.
- External coating: graphite coating that guarantees a very low friction coefficient
- Structure: reinforced in order to offer resistance to the stress suffered by cylinder units used for top-level competition, but at the same time light enough to reduce inertial force.
- Ring: 1 mm nodular-cast-iron single ring with rectangular cross section and hard-chromium coating on outer surface.
PISTON RINGS
- Rings in very strong modular cast iron with ground, wear-resistant, hard chrome metal-spray coating on the contact surface.
HEAD
- 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.
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

Frequently asked questions
Faq
-
Looking at the barrel, I noticed strange marks on the exhaust sleeve. Is it normal for them to be there?
This is a deliberate machining. As high temperatures are reached at this point with strong expansion, this machining was done to lower the point in order to avoid seizing.

Malossi needle roller bearings are independent bearings that are ready for assembly and constructed from high-tensile steel with housings for the insertion and axial rotation of the rollers. These devices are designed to allow reciprocal movement between two objects, constraining the rotation of the cage and housing the rotating elements with reduced overall dimensions, negligible weight and reduced friction. These are essential components in internal combustion engines which, by definition, have several rotating elements. As can be seen in the image, a needle roller bearing assembly is made…
