The ultimate cylinder for vertical Minarelli engines: the Stage6 Cylinder Kit MKII Sport 50cc MBK Booster / Stunt, a street to midrace cylinder at an affordable price.

It comes with a 2-ring piston, is made of Nikasil-plated aluminium, has 5 transfer ports and an oval-shaped exhaust port. 

Definitely a perfect compromise between reliability for everyday riding and outstanding performance. Needless to say, you can optimize performance by adjusting your carburetor (jetting) and variator (weight and spring adjustment).

And to round it all off for maximum power, we recommend running this cylinder with a sports or racing exhaust (such as the Yasuni R), a sports variator, a 19mm carburetor and a Malossi CDI. This should add up to 10hp / 7.5N.m torque.

The kit includes:

  • Cylinder
  • High-compression cylinder head
  • 2-ring piston, 10mm
  • Gasket set
  • Stud bolts
