Athenas crankshaft are made of premium materials combined with the latest production technology.

These products are also suitable for tuned-up engines and ensure maximum performance that lasts over time. Athena offers the following range of crankshafts:
a) Original: perfect replacement for the original crankshaft, but with improved balance and a lighter connecting rod. Each kit includes a special bearing cage.
b) Racing: available with hole for wrist pin of small end casing measuring 10mm or 12mm. Available with a lighter crankshaft and special bearing cages. Differs from the Original Kit for its solid crank shaft handles, made entirely by milling to reduce the volume of the crank handle case.
