Description

If the pistons and/or cylinders are oval due to wear or damage, never replace just one piston or cylinder, but replace all four simultaneously.

All sets are delivered complete, including 4 pistons with 4 piston rings, 4 cylinders, 4 piston pins, and retaining clips.

If you want to increase the power output of your engine, this is sometimes possible without having to modify your crankcase, but keep in mind that the stroke length and dimensions in the crankcase must remain the same, while the cylinder heads may need to be modified (bored out) or replaced with a cylinder head of the correct inner dimension.

We have provided the key data to ensure that you order the correct cylinder and piston set. Please verify this before ordering.

The listed cylinder capacity is the exact value, typically rounded to 1200, 1300, 1500, etc., colloquially. The rounded values are indicated in parentheses as extra information. The dimensions indicate the required space in the crankcase or cylinder head, with the cylinder size being slightly smaller.

Suitable for:
– Type-1 engines
– Type-3 engines
