Malossi Racing Cylinder and CDI for Aprilia SR50 Di-Tech liquid cooled SR models with the Aprilia (Morini) Engine. Not for the Piaggio Engine.  M 3112043, M3112043, PI3112043

Malossi, whose expertise in balancing a vast experience with the latest technology, embraced this new challenge: to bring to the racetrack a fuel injected two stroke engine.
With the new INJECTION TECH range of products a new chapter is written, an answer the racing world was anticipating, to satisfy the growing number of Malossi Trophy Races for 70cc scooters.

CYLINDER - Technology
- Material: special self-lubricating, wear-resistant, highly refined cast iron alloys, obtained by Shell Moulding gravity die-casting.
- Machining: on numerically controlled high precision machine tools.
- Recalculated heat exchange surfaces.
- Exhaust and transfer ports designed and tested for maximum thermodynamic performance.
- Shape and surface texture dimensional checks.
- Cylinder and piston selected for a 100% fit of 0.010-0.005 mm.
- Checking of all the seals carried out.

PISTON

- Material: special aluminium alloy with high silicon content and low thermal expansion.
- Machining: on numerically controlled machine tools.
- Lightened and strengthened.
- Heat exchange surfaces increased.

PISTON RINGS
- Ringswith ground, wear-resistant, hard chrome metal-spray coating on the contact surface.

HEAD
- Material: special die-cast aluminium alloy.
- Geometry of heat exchange surfaces recalculated and increased (air-cooled models).
- Cooling circuit sections and paths recalculated and resized (liquid-cooled models).
- Machining: numerically controlled high precision machines with diamond tools.
- Surface rust prevention treatment.

NOTICE:
FOR THE PROPER WORKING OF THE KIT IT IS ABSOLUTELY NECESSARY TO USE THE CDI UNIT SUPPLIED IN THE KIT.
