Original 39 mm cylinder kit incl. add-on parts for your Zündapp Belmondo moped / moped.
Fits Zündapp Belmondo mopeds, Zündapp Bergsteiger M25/M50 mopeds, as well as Alpa Spezial 3000 and Alpa Black River small motorcycles which have a Zündapp type 247 engine installed.
Complete cylinder kit incl. original exhaust system. The original carburetor / air filter should be used.
With the right settings, you can get a full 1.6 hp on the rear wheel. For those who want a little more steam, you can switch to the 39 mm or 44 mm tuning set.
The following attributes characterize the cylinder kit:
- Nikasil coating for optimum lubrication and durability
- Split transfer ports for optimized mixture flow
- Fit on the cylinder head for perfect guidance
- pore-clean surface
- All sealing and connection surfaces are flush-mounted
Please select the desired cylinder head with or without decompression bore and the desired exhaust clamp in the selection field.
Note: The original stud bolts of the engine housing are too short due to the height of the cylinder kit and must be replaced with longer bolts (item 24319).
For Zündapp engines with an 85 mm short connecting rod, this must first be converted to a long connecting rod with a length of 91 mm (center - center) in order to use the cylinder.
When purchasing this complete set, there is a substantial percentage off the retail price of the individual parts.
