SIP Spare Parts drive shaft in perfect quality of the original spare part. High-quality replacement for worn-in, corroded, bent or twisted drive shafts.

The top model in the world of scooters from 1955 to 1961 was the Vespa GS 150. SIP not only reissues small parts, such as the auxiliary shaft bearing, which was no longer available for decades, but also this drive shaft, for example. On the models with the prefix "VS1 to VS5" and on the German GS "VDTS", the gearing is particularly often twisted. Now, finally, there is a spare part that surpasses the quality of the original part and is therefore a sensible update even for engines with increased performance.

• For high-performance engines
• Runs perfectly round
• High-precision manufacturing
• Hardness and tempering as original
• Top surface finish

The engine of the Vespa 150 GS still forms the best basis for tuning in the wideframe sector. With a little effort, directly aspirated PX cylinders, such as the Quattrini M1XL, can also be fitted. The SIP drive shaft can easily cope with the resulting power of over 20 hp.

Today, the wideframe drive shafts often show radial runout, i.e. they are bent and wobbly. Sometimes the gears are also worn. No wonder after about 70 years. Rubbing brakes, vibrations etc. can have their origin here. Our new main shaft runs perfectly smooth. It is manufactured to a very high standard and the manufacturer has taken great care to ensure that the material is correct and that the fits and degrees of hardness are correct.

Note: The diameter of the bearing seat on the gearshift side is adapted to the inner diameter of the SIP bearing made of the original red brass material.

Conclusion: This drive shaft from the small series of SIP Spare Parts makes the hearts of many wideframe owners and tuners beat faster.
