Cylinder Gasket Set Stage6 AM6 Big Racing / Streetrace / Sport MK2

Stage6 BigRacing cylinder

The Big Racing cylinders are extremely powerful cylinders for 50cc supermotos. Although they are very powerful high-end cylinders, they offer a good balance of performance and reliability for intensive, regular, even daily use.

The aluminium cylinders have a displacement of 77 to 88 cc (with the corresponding crankshaft ) and were mainly developed for 50cc motorcycles with Derbi and AM6 engine, e.g. Rieju MRT, Beta RR or Sherco.

In combination with a suitable exhaust, a complete intake system and a suitable gearbox, the BigRacing can achieve maximum power with maximum torque and increased top speed.

The Stage6 R/T series delivers even more power, with uncompromising performance for use on the race track.

what does a gasket do?

There are many different types of gaskets or gasket sets in an engine, e.g. cylinder gaskets, intake gaskets, oil seals, crankcase gaskets, exhaust gaskets, carburetor gaskets or engine gasket sets. They all have the same function: to prevent leakage between components.

When and why should you change an engine gasket?

When servicing your two-wheeler or noticing leaking fluids, be sure to follow this one important rule: Always replace an old gasket with a new gasket.
Damaged or worn gaskets can no longer do their job properly, the parts that have to be sealed are no longer adequately sealed, which can lead to serious follow-up damages.

Before you install a new gasket, you must thoroughly clean and degrease the sealing surface.

You can also use silicone sealant as an alternative to paper or metal gaskets in some cases. But beware, O-rings and oil seals cannot be replaced by sealant.
