Cylinder kit Stage6 Sport Pro MKII 50cc AM6
The perfect street cylinder for all supermoto and enduro riders: Cylinder Stage6 Sport Pro MK2 50cc Minarelli AM6. This is a 50cc sport / entry-level tuning cylinder made of aluminum with a highly resistant Nikasil coating. The cylinder was developed for daily use. The motto: simple, powerful and reliable.
Design and performance Sport Pro MK2 aluminum cylinder
The layout of this cylinder is based on that of its big brother, the Stage6 Big Racing. Here, too, you will find the stamped 49 cc marking. Using the Big Racing as a base allows this 50cc cylinder to feature large intake ports and a high cooling volume.
In terms of performance, the Sport MKII easily competes at the top of its class. The generous intake ports allow for good filling, while the exhaust port, supported by boost ports, ensures optimum exhaust flushing. The port timings (118° - 181°) offer a wide usable powerband and guarantees an optimized engine character with loads of riding fun across a wide rpm range.
To take full advantage of the performance of this Stage6 MKII Sport Pro 50cc cylinder, we recommend combining it with a minimum 21mm carburetor and a Stage6 Streetrace exhaust (or a comparable model). Attention, if your crankshaft has more than 5000 kilometers on it, we recommend replacing it with a new, reinforced crankshaft.
sport cylinder with maximum reliability
To ensure maximum reliability, Stage6 opted for a 2-ring piston. Using a 2-ring piston slightly reduces the cylinder's power output but significantly increases its service life. As already mentioned, the construction of this cylinder is based on the large Stage6 Big Racing and also features a large-volume cooling system to keep the engine efficiently cooled while riding.
All in all, the ideal cylinder for city and country rides, with plenty of power and excellent acceleration.
At the bottom of the page you will find various parts to get the most out of this kit.

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.
