General information about this item
Product info
The cylinder/piston set 1-055121, featuring a new ASSO piston and a cylinder ground to 69.00 mm with cross-hacking, provides the central compression unit of the 250 cc BMW Isetta export engine in technically like-new condition. For restoration projects, this ready-to-install set with painted cooling fins offers a reliable foundation for permanently eliminating compression losses and thermal issues associated with an aged cylinder. This allows the engine to be overhauled in a way that is both stable and true to the original.
