Stage6 cylinder kit Sport MK 2 70cc
Stage6 Cylinder Kit 70cc Sport MK2 10mm piston pin Minarelli horizontal AC (Yamaha Neo's / MBK Ovetto). The first generation Sport MK1 cylinders became very popular among scooter tuners, then Stage6 took things to the next level and introduced the successor, the Sport MKII.
For 50cc scooters with Minarelli horizontal AC engine such as MBK Ovetto or Yamaha Neo's.
Design Stage6 MK2 cylinder
The cylinder was completely redesigned; 6 instead of 5 transfer ports ensure optimized cylinder filling. The oval exhaust remained but was optimized as well. The appearance is based on the pentagonal shape of the R/T cylinders. The head is a one-piece unit with cast scavenging canals for better heat dissipation. The piston is a replica of the R/T piston, with a domed piston crown and 0.8 mm thick piston ring to optimise performance and improve thermal stability.
Performance 70cc cylinder MK2 from Stage6
The cylinder delivers 2 to 3 hp more power than the MK1, between 14-17 hp, without any additional modifications and in combination with the corresponding components. Maximum performance and outstanding robustness - we are sure that this cylinder will set new standards in the tuning scene.
We recommend using a reinforced crankshaft, a min. 19mm carburetor and a sport / racing exhaust to exploit the full power of this tuning cylinder.
Installation tips for Stage6 cylinders
We recommend to clean the engine before assembly, check the condition of all components and use a new spark plug and new small end bearing. Do not forget to change your carburetor settings if necessary.
Squish clearance should be between 0.75 and 0.85. The cylinder should be run in for approx. 300 km with a 1:33 mixture to improve robustness and life expectancy.
Attention: Original exhausts cannot be mounted with this cylinder.

The service life of a cylinder depends on whether it has been fitted correctly.
Tuning Level: Sport
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.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
