Crankshaft -BGM Pro HPC 58mm stroke, 110mm connecting rod- Lambretta DL / GP 125cc, 175cc, 200cc, 225cc, 250cc

Article no. BGM11063G

Forged full circle shaft with Yamaha connecting rods.
Great emphasis was placed on balancing during development. Thanks to tungsten weights (100 g per crank web), copper weights and hidden pockets, the shaft has an exceptionally high balance factor. This ensures particularly low-vibration engine operation.
The longer connecting rod offers a better deflection angle and thus relief for the lower connecting rod bearing. The longer connecting rod is balanced with a 3 mm foot spacer. The lower connecting rod bearing is lubricated via two large lubrication slots. The open silver cage bearing can cope with the highest demands.
The diameter of the crank pin is 22 mm. In connection with the correct undersize to the crank web and a special adhesive as a lubricant, the shaft is perfectly protected against twisting.
CONCLUSION: The bottom line is that the bgm crankshaft offers the highest quality in all respects. From every component to the manufacturing accuracy to the materials used.
