The bgm EVOLUTION crankshafts are very cleanly processed and convince with well thought-out details: performance-optimized full-beam design well balanced (special balancing that is only available with the 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 the 105mm series). This ensures smoother running, less piston load and more leeway for setting the cylinder control angle. CONCLUSION Very nice, stable and well balanced crankshaft which should be the basis for a perfectly healthy structure in every engine. SPECIAL FEATURES LONG STROKE The 55mm long stroke shaft makes it possible to obtain more displacement and longer cylinder control angles in an elegant way. The performance can be significantly increased again. Please note that the additional stroke of 3mm must be compensated for with a corresponding compensating seal of 1,5mm on the cylinder head or cylinder base. The supplied spacer with 5mm only compensates for the longer connecting rod. The additional stroke of 3mm must therefore be compensated for by a 1,5mm gasket or a correspondingly turned cylinder head. A base seal increases the control angle of the cylinder and thus creates the conditions for a sporty and speed-oriented performance development. For full performance, however, the outlet angle often has to be increased.
