Reinforced crankshaft 40mm long stroke ITALKIT RACING 12mm axis for scooter Suzuki KATANA, ZILLION, APRILIA MOJITO, SR ...

ITALKIT HYPER RACING crankshaft in long stroke 40mm against 37.4mm for the original, this crankshaft saves in displacement and therefore in torque, power ... With its 2.6mm of stroke in addition (requires a wedge of 1.3mm under the cylinder, so 2 very thick base gaskets), it offers a lot of additional displacement!

Examples :
-All original: 41mm cylinder diameter, 37.4mm stroke = 49.00cc
-Long stroke crankshaft with original cylinder: Cylinder diameter 41mm, stroke 41mm = 53cc

Original stroke crankshaft with Ø47mm kit: 65cc

Long stroke crankshaft with Ø47mm kit: 69cc

It is therefore a gain of 4cc of torque and power that is offered by this crankshaft, apart from that, it is specifically balanced for less vibrations and good performance! Its fuller masses offer more pre-compression in the lower engines for even more performance gains! Well reinforced, this crankshaft is strong enough to support the largest kits on the market! The connecting rod remains original size, this crankshaft also exists in 85mm long connecting rod!

Mounts on : SUZUKI scooters like the KATANA, ZILLION ... APRILIA SR, MOJITO ... 50cc
