Description

If the pistons and/or cylinders are oval due to wear or if they are damaged, 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 extract more power from your engine, in some cases this is possible without having to modify your crankcase for this purpose. However, keep in mind that the stroke length and dimensions in the crankcase must remain the same, while the cylinder heads must be modified (bored out) or replaced with a cylinder head with the correct internal dimensions.

We have provided the key data to ensure that you order the correct cylinder and piston set. Please double-check this before placing your order.

The specified cylinder capacity is the exact value, which is commonly rounded to 1200, 1300, 1500, etc. We have indicated the rounded values in parentheses as an additional reference. The dimensions indicate the required space in the crankcase or cylinder head, so the cylinder size is slightly smaller.
