DRT responds to the POLINI Racing Cylinder developments and satisfies all fans of the 135 cc class with its 53 mm Shaft.

The Long Stroke Crankshaft has the stable, blunt ETS Cone with 20/25 mm Oil Seal/bearing seat. The fully round LIMA cheek has a diameter of 86 mm . With a stroke of 53 mm, a 57 mm Cylinder achieves the 135 cc required in the Italian racing class. The polished 105 mm Conrod outperforms the POLINI Shaft and ensures an adapted pre-compression, higher filling ratio and more power in all areas. Lubrication slots ensure optimum lubrication of the lower connecting rod bearing.

Conclusion: Best price-performance ratio in this class with excellent workmanship.
