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

Attention! It is necessary to carry out balancing checks before installing in the engine, since manufacturers deny warranty for any balancing fault found after installation.
