The cylinder is engineered specifically for a crankshaft with a 60 mm stroke and 127 mm connecting rod. SIP stocks a range of compatible crankshafts, and POLINI offers crankshaft 21000950 as a dedicated match. A standard PX200 Long Stroke Crankshaft with a 110 mm conrod is incompatible with this design.
The redesigned Cylinder Head features eight attachment points, a centring mechanism, and a copper gasket for secure assembly and reliable sealing. An integrated decompression bore eases kick-starting of this large-displacement engine.
