Here is one of the best value for money on the market offered by ARTEK. The ARTEK K1 crankshaft is a reinforced, balanced and full-mass model for vertical minarelli. It is really intended for the reinforcement of the low engine and for performance.
The steels used are of the highest quality, they are treated and well hardened, the balancing is dynamic and really neat! For more pre compression, the masses are full with special coating. H-shaped forged connecting rod which is placed on a reinforced crankpin and a well-raised cage with anti-friction wedges.
Grease points at the top and bottom of the connecting rod were used for increased reliability. Thanks to its architecture and its quality, this crankshaft can take a rotation speed of 14000 rpm! Neat dynamic balancing. Delivered complete, as in our photo, with its reinforced needle cage.
In short, this crankshaft will withstand most fitted engines, it offers excellent performance and resistance to height. For engines intended for larger and more efficient revs, we still prefer to use the K2 model, which is certainly more expensive but designed to support larger engine configurations!

-Course: original 39.20mm
