Crankshaft, connecting rod assembly ATHENA Hyper Racing race 40mm for mécaboite driving DERBI euro 1 & 2 except GPR

Here the crankshaft reinforced ATHENA HYPER RACING for DERBI euro 1 & 2 without balancer (thus except model DERBI GPR). This top model is above the ATHENA RACING! It is in full masses and fully reinforced.

His balance is excellent. He'll know your stand on 50cc and 80cc kits, he shall bring you extra performance thanks to its full masses but also of longevity thanks to its reinforcement, its balancing ... Enough heavy, it offers good engine inertia. It is obviously fitted with a reinforced rod, super lightweight and a plus big end cage, the lubrication are all reviewed and corrected.

The cage rod feet preserves the size origin namely Ø12X15X15mm but it is reinforced and treated. It is clearly better than STANDARD ATHENA RACING, it offers fuller masses for more pre compression and a true balancing.
