Cylinder base spacer SRC, Piaggio 125-180cc, thickness: 1.5mm

Cylinder spacer

Cylinder spacers should only be used by experienced tuners who have enough know-how to understand the complex workings of an engine and implement the corresponding measures.

What is the benefit of a cylinder spacer?

A cylinder spacer may be necessary if you are using a long-stroke crankshaft, as the piston rises higher in the cylinder to increase displacement.

With a 2-stroke engine, however, you cannot simply raise the cylinder. Raising the cylinder will also increase port timingd, which will completely change engine behavior; it can also result in a significant loss of power at low engine speeds.

If you want to use a spacer, make sure that the crankshaft, connecting rod and cylinder are designed for it or are compatible.

Note: Cylinder spacers vary from engine to engine. Their thickness must be matched to the crankshaft and cylinder. Please also remember to order cylinder studs in the correct length.

Tuning Level: Racing

We categorize our products into different performance levels  Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.

Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
