VORTEX high-end engines are unique, their totally cylindrical shape is ideal, because it allows a better circulation of the coolant.
They are recognizable among all VORTEX high-end engines because they are 5-transfer scavenging with a bar exhaust.
It has a nikasil coating, so its surface has a low coefficient of friction and high resistance.
The VERTEX brand elliptical piston has two hard chrome steel rings ensuring increased reliability.
- New casting for better homogeneity of cooling
- Nickel-plated aluminum cylinder
- 5 transfers
- Bar exhaust
- Two-ring piston for better longevity and reliability
- Hemispherical cylinder head with squish and central spark plug for better combustion
For optimal assembly we recommend a BR10EIX spark plug or, failing that, a BR10ES spark plug.
