Malossi Piston 80cc Yamaha DT

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

The range goes from size 0 (smallest piston) to size D (largest piston). Each 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 (e.g. 34 3448.20 – 34 4375.60).

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

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

The piston must be inserted into the cylinder with the arrow drawn on the piston crown facing the exhaust.
