MAXISCOOT 70cc Cylinder Kit "MXS Sport" MBK Booster / Stunt (10mm piston pin) - developed by Maxiscoot's Racing Team!
The Nikasil-plated aluminium cylinder has 5 transfer ports and an oval exhaust port. The kit comes with a HQ single-ring piston (10mm pin) and a high-compression cylinder head (port timings: 189.4°/123.6°/125.8°).
To unlock the full potential of this kit, we recommend running it with a 21mm (at least 17.5mm) carburetor and a sports exhaust (such as Yasuni R, Doppler…); you can even run it with your original exhaust.
With the right set-up and adjustments, this sports kit can reach record-breaking 16hp!
The kit comes with complete piston (pin, circlips and ring included) and the proper gaskets for mounting. To make sure to get maximum power and reliability out of this cylinder kit, you should definitely adjust "squish clearance" when mounting it (cylinder spacers are included).
For vertical Minarelli engines
Bore: 47.6mm - Stroke: 39mm
Note: piston pin = 10mm.

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.
Tuning Level: Racing
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.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
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.
