Pistons of the 175cc Lambretta models.
Available in the original bore diameter (Ø=62.0mm) and three other oversize piston sizes.
The oversize pistons are suitable for reusing worn or defective cylinders. For this purpose, the cylinder is ground (drilled) to the dimension indicated on the piston in an engine overhaul and then honed.

Can also be used to bore out a standard 125/150cc cylinder.
The 40% increase in displacement makes driving much more confident and pleasant.

EXPERT TIP: Modify the control angle of the cylinder as well. For a fast touring engine you should aim for: 165-175° exhaust angle, 120-125° overcurrent angle and 140-145° intake angle. The lower values are tamer, the higher values are correspondingly sportier.

NOTE: The 175cc engines have connecting rods of different lengths depending on the model.
Therefore there are also different pistons which differ in the compression height (distance connecting rod eye to piston crown).
