Please note, this crankshaft increases the engine displacement, it is in no case approved or authorized on the road. New from us!
Here is the MAZZUCCHELLI crankshaft, 44mm stroke. This crankshaft in this 44mm long stroke will allow you to directly increase your engine displacement whatever the high engine you install. However beware, the passage in long race increases the diagrams, so do not put a kit that has very large diagrams in 39mm race on a 42mm race under penalty of obtaining unusable diagrams. We totally recommend the passage of a 50cc kit (d.40mm) in long race, you would turn in hyper race….
In short, the 44mm race if well accompanied will prove to be a very big gain in torque and performance. If you want to put it on a normal racing kit as you need to provide a 2.5mm thick shim! You also need to plan to align the lights in the bottom dead center for the best, we recommend checking the diagrams during assembly. Apart from that, this crankshaft remains fairly correct in relation to its price, the masses are full for more pre compression, balancing is carried out digitally….
The finish is good, the connecting rod and the steels used are high-end. The big end cage is also revised upwards for more solidity.
