Gasket set cylinder Aprilia Minarelli, MBK, Yamaha 50 ccm, LC

It does not always have to be a new cylinder?

Does the cylinder have little or no power? After a few thousand kilometers. the piston rings or even the piston should be replaced to ensure a reasonable compression.

For all current tuning and original cylinders we have the most important spare and wear parts for you in stock. i.e. pistons. Gasket sets and piston rings.

Piston rings are the link between piston and cylinder bore. They are therefore also subject to heavy wear and should be replaced regularly. Loss of compression. Declining performance and poor starting behaviour are a clear indication of worn piston rings.

Piston ring set/s = complete set. 2 piston rings Piston ring= single piston ring. 1x standard dimension= original dimension

1st OCT / 2nd OCT = 1st interference. 2. oversize etc.
Ø = gives the diameter of the cylinder!
an L- piston ring = piston ring with L-shaped cross-section. also called Dykes ring

Our TIP: Mount piston rings carefully. do not overstretch. there is otherwise a risk of breakage. Piston ring joint clearance. Note type and design. Trapezoidal rings have only one installation direction!
