Complete set of Mahle forged 2180cc stroker 92mm barrel and pistons designed as an upgrade to your Type 1 1300cc + 1600cc aircooled engine Stroker barrel and piston sets are designed to make engine assembly easier when fitting larger stroke crankshafts. This is typically achieved by a combination of longer barrels or shallower compression height. By using this type of barrel & piston not so many barrel spacers will be required when doing final set up of deck height and compression ratio.
