PRODUCT DESCRIPTION 

Crankshaft Long Stroke BGM Evolution 2 55mm Stroke 110mm Conrod

INFORMATION 

The BGM EVOLUTION crankshafts are very cleanly processed and convince with well-thought-out details:

  • performance-optimized solid beam design
  • well balanced (special balancing only available on BGM PRO shafts)
  • stable connecting rod
  • available with 52mm (std.) and 55mm stroke

The long stroke version with 55mm stroke has a longer connecting rod (110mm instead of 105mm as series). This provides a smoother running, less piston load and more leeway for adjusting the cylinder control angle.
