Crankshaft BARIKIT, Derbi Senda | GPR | D50B0, BRK 43mm sword connecting rod

Racing crankshaft from our racing forge BRK. The full circle shaft with polished sword connecting rod not only improves your pre-compression, but also the air flow in your crankcase. Another advantage of the polished connecting rod is the smooth surface, which reduces the notch effect and increases the strength of the component. The stroke is 43mm, so the cylinder has to be adjusted accordingly and you get 85cc on your engine. You can find a suitable cylinder in our shop.
