The crankshaft below is a special unit with an 80mm stroke (believe me this is the longest stroke that a standard A112 block can manage). This combined with a 68mm bore will give a displacement of approx 1150cc.

The crankshaft is basically a fully counterweighted 5 main bearing crankshaft, but with only three of the main journals ground. Weight wise it compares quite favorably with the standard A112 crank. Made of the heat treated 4340 steel, this is the best combination of design and material available today.
This crankshaft can be ordered to fit A112A1, A112A2, 1000OT, AH, Bialbero and 1000SP applications in the following strokes to give various displacements.
63.5mm
68mm
69mm
70mm
74mm
80mm
These crankshafts are special order and take approx. 6 weeks to complete.
