BGM Pro gear parts are ultra-solid material. For the highest demands, the gears are made of high-alloyed NiCrMo case hardening steel (20NiCrMo2-2/ AISI8620). The precisely defined surface hardening to 58-60HRC makes the sprockets extremely resistant to wear. Better than Piaggio Ware. Always consistently high quality. No compromises.
