Description
Stage6 Piston Big Racing 77cc 50mm Minarelli AM6 / Derbi, spare piston for Stage6 Big Racing 77cc cylinder kits.
When you start noticing a loss of compression and / or power, it's time to replace your piston with a new one. Including piston pin, piston ring and circlips.
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.

When to replace the piston?
To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).
Extending Piston life
To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.
It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
