Crankshaft Stage6 Stroke 55 Connecting Rod 110 Piaggio 125-180CC

HPC CRANKSHAFT FOR ORIGINAL AND TUNING SETUPS BY STAGE6

The crankshaft Stage6 HPC stroke 55mm / connecting rod 110mm for Piaggio / Gilera 125 - 180 cc 2-stroke, the perfect addition for original and sport cylinders, whether for moderate or significantly increased performance. The Stage6 crankshaft also meets ambitious requirements, especially when it comes to engines with significantly higher performance.

The high-quality solid crankshaft is internally relieved on the shoulder side in such a way that an excellent balance is achieved with the opposing copper balancing weights. The result: a smooth engine run for a wide range of applications, whether for street, circuit, or sprint races. The high-quality forged connecting rod with silver-forged finish completes the set.

In the current version, the connecting rod is 110 mm long, with a crankshaft stroke of 55 mm. The modified piston stroke from 52 to 55 mm increases the cylinder capacity from 175 to 185 cc, resulting in more torque and peak power across the entire rev range. A cylinder head spacer is needed to adjust the length of the stroke and the timing. These are included in the delivery and allow for plug & play installation.

The connecting rod is 5 mm longer than the original, the volume in the engine increases, this reduces the pre-compression and provides more fresh gas for the overflow. If you follow this approach, this crankshaft is the best choice! The corresponding 5mm spacer is also included.
