MATERIAL
The bgm PRO Touring crankshafts are forged. The material is dense, thereby initiating the heat better and thus warp resistant. In addition to the crank arms and the connecting rod is forged and then CNC machined.

STORAGE
The lubrication of the lower connecting rod is via two large lubricating slots and four additional side pockets. The SSC racing bearings and lateral thrust washers provide a solid storage. The lubrication of the upper connecting rod via two lubrication holes. The INA end bearing is supplied with the crankshaft.

HUB
The shaft is available with 60mm (long stroke) and with 57mm (standard) Hub. With the Langhubvariante more displacement is achieved, at the same time the steering angle of the cylinder (overcurrent and outlet channels) can be altered performance-enhancing.

INLET ANGLES
The bgm PRO Touring wave has compared to many other racing waves a clear better layout of the intake time. When tuning cylinders the standard wave comes not with their very short intake time. The bgm PRO wave contrast closes on a PX motor housing about 58-65 ° after top dead center (depending on the motor housing that is factory differently). The motor can be matched well with this control angles. TIP: If the inlet processed the earlier is the crankshaft free the inlet slot, power can also be obtained. As a good value here has about 120 ° v.OT. arise.

RELEASE
The crankshaft design of the PX engines based on the first 125cc engines from 1960 to about 5 horsepower. Unfortunately Piaggio has this construct never really changed in the subsequent displacement extensions. Thus, the capacity of the crankshaft with the standard 200cc models has already been exploited by calculation with 12PS. The crank arms are very narrow and have very little overlap (cheeks material which, when viewed in diameter, is above the lower crank pin available). This is neither a particularly high crimp still a large crank pin can be used, as would be necessary (for the dedication of modern engines).
The BGM crankshafts are released due to their high quality materials and storage system for up to about 20hp. We recommend the use of a simplified magnet wheel with max for engines in this performance area. 2300gr.

CONCLUSION
The bottom line provides the bgm PRO crankshaft in all respects the highest quality in each component. Precision in the manufacture, materials used and especially the precise balancing leave nothing to be desired. This is an extremely quiet and vibration-free running engine guarantees.
