General information about this item
Product info
The Mahle/Nüral piston with part number 1-0491 (Ø 67.94/67.95 mm, piston pin 20 mm) is designed for the BMW Isetta engine and ensures tight and efficient combustion in the cylinder. During an engine overhaul, cylinder dimensions, piston clearance, and piston rings should be precisely matched to prevent piston tilting, oil consumption, and loss of power. Careful installation and a proper break-in period are crucial for a durable and restoration-quality repair of the Isetta engine.
