Stage6 Cylinder Racing 72cc GY6 / Kymco 50cc 4-stroke

Stage6 has become a household name for top quality tuning components for 2-stroke scooters with CVT / variator. They are now branching out and are getting into the market for the increasingly popular 4-stroke scooters. Their new Stage6 72cc Racing Cylinder for Kymco / Sym / GY6 50cc 4-stroke models is a HQ performance-boosting tuning part. And just like with all other Stage6 products, the value you’ll get for your money is excellent.

The cylinder was developed for GY6 4-stroke engines and comes with a very resistant cast iron sleeve to achieve a perfect combination of high reliability and maximum performance. It has a displacement of 72cc, gained by expanding the cylinder bore, which results in a considerable boost to overall performance. Acceleration and engine response are noticeably improved.

It is a mid-race / sport cylinder fit for everyday use. One of the advantages of a 4-stroke engine is the fact that you don’t need any other tuning components to benefit from the power increase produced by this cylinder kit; you can run it with your original set-up. The only thing we recommend checking is the main jet, it may have to be readjusted.

Still - if you want even more power, we recommend combining the cylinder with a tuning variator, a derestricted CDI and a tuning exhaust.

The kit includes:

• Stage6 72cc 4-stroke racing cylinder 
• high-compression CNC machined piston d. 47mm
• piston rings and gaskets
• installation manual

Info:

- The cylinder kit does not include a cylinder head, please use the original head. If you don't have a cylinder head, you might want to order one now.

- For some countries: the cylinder kit has no CE-marking / is not street-legal.
