Product description

Original LML reed-valve crankshaft as an economic alternative.


This crankshaft is standard equipment in the 5-port engine produced by LML India. Good manufacturing at an economic price. LML reed-valve crankshafts, what are their main features?

  • Very good price/performance ratio
  • OEM LML production quality
  • ideal for reed-valve conversion projects on PX motors

 Technical specifications:

  • Stroke: 57mm
  • con-rod: 105mm
  • gudgeon pin: 15mm
  • port timings: 112°/6°
  • inlet web diameter: 97.5mm

Conclusion: These crankshafts represent ideal replacements for standard LML reed-valve motors and are also perfect as an economic alternative when converting a Vespa PX motor to reed-valve operation, due to the inlet side web being around 1mm smaller than the original PX type which improves the gas flow properties.

OEM numbers (for comparisons): C-3721374 (LML)
