Top Performances makes very torquey and durable cylinders: Top Performances Cylinder Kit "Sport" 70cc cast iron Minarelli AM6.

The kit contains the following components:

      • 73,5cc cast iron cylinder (bore 49mm) with 5 transfer ports and simple exhaust port
      • 2-ring piston
      • HC cylinder head, one-piece
      • gaskets

The cylinder kit is ideal for all those who want a little more power distributed over the entire rpm range but want to do as little maintenance as possible. The engine speed is similar to the original cylinder, the peak power is in the range of 7.000-10.500 rpm. The Top Performances cast iron series is characterized by extremely high durability and reliable performance, built for daily, intensive use and long distances.  

With a larger carburetor (17,5mm or even 21mm), you can get up to 10 to 12 HP out of this kit. We recommend adding a 70 - 80cc sport tuning exhaust, it will extend rpm range again.

      • Squish clearance is preset, a cylinder base gasket is included.
      • Running-in: about 300km (150km with ½ throttle and 150km with ¾ throttle).
      • If you keep the oil pump, we recommend using Stage6 oil optimal flow characteristics to prevent the pump from clogging.

The 70cc cylinder ist not street-legal (depending on country)!
