Athena 80cc Cylinder Kit “Sport Pro” (43mm stroke) for MBK Booster / Stunt (Minarelli vertical).
The kit includes:
- Nikasil-plated Aluminium Cylinder, with 5 transfer ports and “simple” trapezoid exhaust port
- One-Ring Piston, 12mm pin
- High-Compression Monobloc Cylinder Head
- Gasket Kit for mounting and adjusting squish
Being the “big brother” of the 70cc Sport pro cylinder kit, this kit has the same technical specs, but has to be used with a 43mm crankshaft (and 85mm connecting rod).
From the get go this kit will get you 80cc! Just like the 70cc, this “80cc Sport Pro” has plenty of torque at mid rpm range and, consequently, very impressive acceleration.
With a 21mm carburetor and a racing exhaust you can easily get 14/15hp on vertical Minarelli engines. It is also a cylinder ideally suited for working on due to its capacity and top quality workmanship.
Note: just like with all aluminium cylinders, you’ll have to adjust squish to ensure reliable performance and maximum power.
