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.
