Athena Cylinder 80cc Minarelli vertical stroke 43mm

Athena 80cc "Sport Pro" Cylinder Kit (43mm stroke) for MBK Booster / Stunt (Minarelli vertical).

The kit includes:

- Nikasil Aluminum Cylinder, with 5 transfer ports and a "simple" trapezoidal exhaust port

- Single-ring Piston, 12mm pin

- High compression Monobloc Cylinder head

- Gasket set for assembly and squish adjustment

Being the "big brother" of the 70cc Sport pro Cylinder kit, this kit has the same technical specifications, but must be used with a 43mm crankshaft (and an 85mm connecting rod).

This kit will give you 80cc with very impressive acceleration.

With a 21mm carburetor and a racing exhaust, you can easily achieve 14 / 15hp on Minarelli vertical engines. It is also an ideal Cylinder to work on due to its capacity and high-quality workmanship.

Note: as with all aluminum Cylinders, you will need to adjust squish to ensure reliable performance and maximum power.
