Description

Cylinder kit Schmitt GST-60 Limited Edition for Simson M500

Schmitt GST-60 Limited Edition cylinder kit as CNC reed valve conversion suitable for Simson M500 crankcases.

Schmitt GST - Exclusive tuning for Simson

The exclusive Schmitt GST-60 Limited Edition cylinder kit has been specially developed for use with Simson M500 crankcases. The kit is manufactured in small batches by a traditional local company. Modern 5-axis CNC milling machines are used to prepare the cylinder for precise ports and prepare the unit for the Schmitt reed valve case. The precise CNC processing ensures 100% symmetrical ports and optimal angles, delivering high-quality, reproducible results.

Attention: This is a very exclusive cylinder for professional tuning. You need to have a certain amount of know-how to be able to use this cylinder at all. Of course, we also stock "normal" cylinders in our shop.

Features and advantages of the Schmitt GST-60 kit

One unique advantage of this kit is its specially designed flat surface, which, thanks to CNC machining, provides a strong, leak-proof connection to the membrane intake box without the need for traditional screws. For best results, we recommend applying standard surface sealant for optimum sealing.

The cylinder kit features numerous technical features tailored to the requirements of tuning experts and Simson fans:

  • Bore: 41 mm
  • Displacement: 60 ccm
  • Port design: Large, optimized 2-channel system
  • Boysen ports: 5-axis CNC milled
  • Boost ports: 5-axis CNC milled
  • Reed valve intake: Optimized for the STT49229 reed valve case and precisely CNCmachined on a 5-axis
  • Exhaust port: Provided without modifications, giving tuners maximum flexibility

Scope of delivery

The Schmitt GST-60 Limited Edition cylinder kit includes the following parts:

  • Schmitt GST-60 cylinder
  • Schmitt AlMot sport piston (piston window must be machined by the tuner)
  • Schmitt reed valve case STT49229

Notes and Safety

How to Install a cylinder on a scooter, motorcycle or moped

The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.

The service life of a cylinder depends on whether it has been fitted correctly.

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.
