Here is one of the best value for money on the market offered by ARTEK. The ARTEK K1 crankshaft is a reinforced model, balanced and in full masses for DERBI EURO 3 and 4. It is really intended for the reinforcement of the low engine and the 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 a special coating. Forged H-shaped connecting rod which is placed on a reinforced crank pin and a well increased cage with anti-friction wedges. Grease points at the head 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. Comes complete, as in our photo, with its reinforced needle cage. In short, this crankshaft will withstand most engines fitted, it offers excellent performance and strength to match. For engines intended for higher and more efficient speeds, we will still prefer to use the K2 model, which is certainly more expensive but designed to support larger engine configurations!
