MATERIAL The bgm PRO Touring crankshafts are forged. The material is denser, so it dissipates heat better and is therefore more resistant to distortion. In addition to the crank webs, the connecting rod is forged and then CNC machined. STORAGE The lower connecting rod bearing is lubricated via two large lubrication slots and a total of four additional pockets on the side. The SSC racing bearing and the side thrust washers ensure solid storage. The upper connecting rod bearing is lubricated via two lubrication holes. The INA piston pin bearing is included in the scope of delivery of the crankshaft. STROKE The shaft is available with a 60mm (long stroke) and 57mm (standard) stroke. With the long-stroke variant, more displacement is achieved, while the control angle of the cylinder (overflow and exhaust ports) can be changed to increase performance. INLET ANGLE The bgm PRO Touring shaft has a significantly better entry time layout than many other racing shafts. With tuning cylinders, the standard shaft with its very short intake time does not keep up. The bgm PRO shaft, on the other hand, closes on a PX motor housing approx. 58 ° after top dead center (depending on the motor housing this is different from the factory). The engine can be fine-tuned with these control angles. TIP: If the inlet is machined so that the crankshaft releases the inlet slot earlier, additional power can be gained. A good value here has proven to be approx. 120 ° from TDC. surrender. ...
