Athena offers a wide range of cylinder kits for scooters and
motorcycles with diameters and portings completely re-designed as
original spare parts and / or specific boost to be used on tracks. In
particular, racing kits consist of lighter pistons with a flat head,
special portings, exhaust bridge, and a new cylinder head designed to
increase the compression ratio and improve internal combustion. For some
models Athena also supplies special long stroke racing kits complete
with crankshafts and reinforced connecting rods.
