General information about this item
Product info
The cylinder/piston set 1-05521 for the 300 cc BMW Isetta export engine replaces worn original parts and restores proper compression through the precise fit of the piston (73.94 mm) and the cylinder, which has been ground to 74.00 mm. The expert cross-finish and heat-resistant coating ensure optimal lubrication, running-in performance, and corrosion protection—ideal for a long-lasting engine overhaul as part of a restoration.
