This Top Performances 85cc Cast Iron Cylinder + Crankshaft Kit 44mm AM6 includes a cast iron 49.5mm cylinder kit and a 44mm stroke crankshaft for a displacement of 85cc!

The kit includes:

  • cast iron cylinder with 49.5mm bore
  • 1-ring piston with domed head
  • modular cylinder head
  • cylinder gaskets
  • crankshaft with 44mm stroke
  • small end bearing

We recommend combining it with a 21mm carburetor and a racing exhaust (such as Yasuni R3, Pro Race, SCR Racing Line, etc.). This cylinder + crankshaft kit is very powerful and can, when pushed to the max, give you appr. 18 to 19hp. Acceleration and torque will be considerably improved, especially at mid to high rpm range. As a cast iron kit. it is also very dependable and long-lived.

Note: crankshaft bearings and oil seals are not included. As one of the crankshaft's journals has a 20mm diameter, 2 different sized bearings are needed; article no. 6303 and 6204 (an AM6 and a Derbi bearing).

Displacement 85cc / piston diameter 49.5mm / stroke 44mm, not street-legal!
