Professionally bored to Ø 52 mm, this Addy E50 4-bearing racing engine case is designed for your Puch moped.
The milled-out design allows for the installation of large 47 mm cylinder kits, such as those from Gilardoni Italkit, Airsal, or Parmakit. The slightly enlarged cylinder mounting surface ensures that aftermarket cylinders still have sufficient sealing surface area.
The housing was specifically designed and manufactured for the tuning market; therefore, some components—such as the mounting surface for a kickstarter—have been omitted.
The housing features the following special characteristics:
- enlarged sealing surface in the area of the cylinder base
- Casing screws slightly offset outward, leaving more space for larger overflow channels
- A milled surface prepared for GME intake systems
- Alignment pins for secure positioning when assembling the housing halves
- Additional threads for more flexible ignition system installation
- Extra-large cooling fins in the lower section for better heat dissipation and thus reduced wear on the crankshaft bearings
- Stand mounts, 3 M6 threads at the original spacing
- Approved for all SAM moped racing and moped cross categories
- Cylinder stud hole pattern: 44 x 44 mm
Installation tips:
- Using the included washers, different gear wheels with varying positions—such as those in 3-bearing or MBR transmissions—can be properly spaced. Before assembly, be sure to check that the gear wheel is properly centered.
- Use the following screw lengths: 7 pcs. M6 x 35 mm / 6 pcs. M6 x 50 mm
Note: If you plan to use a center stand, we recommend using a sturdy center stand, as there is a stand stop only on the left side.
