Crankshaft, connecting rod assembly ATHENA Racing race 40mm for mécaboite driving DERBI euro 3 & 4

Here is the reinforced ATHENA Racing crankshaft for mécaboite driving DERBI euro 3 and 4. This model is able to withstand high-performance and torquey 50 / 70cc kits without problems thanks to its reinforced copper-coated steel rod mounted on anti-friction wedges, big end increased with revised and corrected lubrication.



Equipped with full masses for maximum pre-compression, its weight will give it maximum inertia. Created with high-end case-hardened steels, this crankshaft has ignition keying. Like the racing model, we will regret a balancing which is not at the top ... Obviously delivered with a reinforced needle cage, original size Ø12X15X15mm. Clearly, a very good element that will accompany a high performance engine, a quality present and visible!
