The VORTEX cylinder kit are unique, their totally cylindrical shape is ideal, as it allows a better circulation of the coolant.
They are recognisable among all VORTEX cylinder kits because they are 5-transfer sweep engines with a bar exhaust.
It has a nikasil coating, so its surface is low friction and high strength. The VERTEX elliptical piston has two hard chromed steel rings for increased reliability - New casting for better homogeneity of cooling - Nickasil aluminium cylinder
- 5 transfers
- Exhaust with bar
- Two ring piston for a better longevity and reliability
- Hemispherical cylinder head with squich and central spark plug for a better combustion For an optimal assembly we recommend a BR10EIX spark plug or a BR10ES plug.
