Description
Vertex piston 38.21mm oversize 1 for Simson mopeds
High quality 50cc replacement piston from Schmitt, manufactured by Vertex, the premium manufacturer for performance pistons.
Nominal piston size is 38.21mm, oversize 1 for 50cc cylinders with 38mm bore. The pistons are designed to replace the original piston.
The 1mm thin piston rings are hard chrome plated and the aluminum alloy has a very high silicon content. Two additional lubrication holes have been added for the 12mm piston pin. These are offset so as not to weaken the piston pin guide.
Can be used with C-clips or G-clips, with recess for removing C-clips.
The piston is optimally balanced and therefore does not tilt, which increases service life and reduces vertical running marks. The piston ring pins are rounded to protect the piston rings and prevent breakage.
- Diameter 38,21mm (oversize 1)
- 12mm piston pin
- 2x piston rings (1mm)
When to replace the piston?
To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).
Extending Piston life
To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.
It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
Tuning Level: Sport
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
