Crankshaft Airsal Racing Xtreme Derbi Euro 3 / 4 stroke 45mm

This year the people at Airsal have stepped up and have finally developed some crankshafts for their great range of cylinders. The truth is that they have started strong; they really stand out at first glance because of their finish, they are of compact and filled wall to increase compression in the crankcase. On the other hand, we have the connecting rod, fully polished to avoid excess temperature, and the cages, which, of course, are made of silver. And finally, something important: this crankshaft can only be installed in combination with the Airsal Extrem 90cc cylinder as it has a 45 stroke.

ATTENTION! 45mm stroke crankshaft! We recommend combining it with the Airsal Racing Extrem 90cc cylinder (C01087550)!

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

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