Description

The shaft has a stroke of 45mm (series = 51mm) and features a 105mm long connecting rod (series 97mm) which has also been widened in its latest evolutionary stage to a proud 5mm thickness. The crank webs are larger in diameter (both sides: 87mm) than those of a series shaft (86.8mm).
As a result, the crankcase must be widened in diameter (spindle dimension 88mm).
The longer connecting rod requires either a matching cylinder or a corresponding spacer.
