Crankshaft, connecting rod assembly CONTI CHR 40mm stroke for mécaboite engine DERBI euro 3 & 4

Here is the strongest crankshaft from CONTI for your DERBI EURO 3 and 4. a reinforced, balanced model is in full masses, it is really intended for the reinforcement of the lower engine and performance, it is certainly the most studied crankshaft of the market. What are the differences with a standard crankshaft? The connecting rod, the materials used, the tolerance to high speeds... . More clearly the reinforcement and the balancing which are even more neat!

The steels used are top of the range, they are treated and well carburized, the balancing is dynamic and really neat! The connecting rod is a very top-of-the-range, lightened H-shaped model with grease at the head and foot of the connecting rod.

It sits on a reinforced crank pin of 18 mm against the original 16 and a much increased cage with anti-friction wedges. Clearly, this crankshaft will resist most highly equipped engines. Able to go up to 18,000 revolutions, it will hold without worries on an MHR TEAM 80cc with internal rotor ignition for example.
