PISTON 47MM 12MM

All Malossi cylinders - both cast-iron and aluminum - are selected by size.

The range goes from size 0 (smallest piston) to size D (biggest piston). Every size features an increase of 0.01 mm.

When ordering a piston, please carefully specify the requested size marking as follows:

Example

• 34 3448          corresponds to size 0 
• 34 3448.A0     corresponds to size A 
• 34 3448.B0     corresponds to size B 
• 34 3448.C0     corresponds to size C 
• 34 3448.D0     corresponds to size D

Only cast-iron cylinders are also available in oversize as follows: 

• 34 3448.40     corresponds to an increase of 0.4 mm 
• 34 3448.80     corresponds to an increase of 0.8 mm

For pistons produced in the past, 0.2 mm and 0.6 mm oversizes are also available (ex. 34 3448.20 - 34 4375.60). 

All Malossi cylinders are selected by size and bear size marking, week number and year. 

All Malossi pistons bear the own size marking (number or letter).
