Crankshaft TOP RACING Honda MTX 50, NSR 50, MBX 50 AC 1990-

Racing crankshaft from Top Racing.
The Portuguese crankshaft specialist has been a guarantee for high-quality crankshafts for years. State-of-the-art production facilities and over 50 years of experience make standard and racing crankshafts the first choice.
The shaft increases the pre-compression in the crankcase, which leads to a significantly better degree of filling. The power speed is shifted to the upper range. The increased flywheel mass of this design not only increases the power, but also the torque. This crankshaft should preferably be used in conjunction with a 70cc cylinder. With a 50cc cylinder, the increase in power is slightly lower.
The crankshaft is supplied including piston pin bearing.
Made in Europe!
