WARNING! To use this crankshaft, it is mandatory to install a lightened flywheel or, failing that, a rotor, since using another type of flywheel may affect the crankshaft and its warranty is completely excluded, as it is intended exclusively for competition use.

Attention! You must carry out balancing checks before installing in the engine, since manufacturers deny any warranty for balancing faults detected after installation.
