Due to COVID-19's impact on Italy, where the major components are manufactured, availability of this alternator is delayed. Expected availability is December. Please check back or email info@euromotoelectrics.com if you care to be notified upon it's availability.

The Ultimate Alternator Charging Kit for your BMW 2 Valve AIRHEAD and MOTO GUZZI with a BOSCH alternator. A simple modern design with fewer components and includes all the installation components to update your under performing BOSCH system. Featuring a permanent magnet rotor which eliminates the brushes and possible rotor failure. The Hi-Output Stator produces significant AC voltage at lower RPM's than the original system and incrementally increases output with higher RPM's. The Combined Voltage Regulator / Rectifier eliminates the two most vulnerable failure items of the BOSCH system, the diode board and voltage regulator.

With correct installation reliability and confidence can be restored to your BMW's charging system - see Installation Instructions on the preparation of your vehicle and installation of the EnDuraLast Charging System in a step-by-step easy to understand manner. The high amperage output of this system at low engine RPM's allows use of additional lighting, heating and other accessories.

  • High-tech permanent magnet rotor will never overheat and short out. Brushless design eliminates worn out rotor slip rings and brushes.
  • Eliminates "burnt out warning light" no-charge condition of Bosch systems
  • Combination electronic voltage regulator /rectifier housed in finned cast-aluminum housing which mounts remotely for increased cooling and reliability (Pt # EDL450-VoltRect). which replaces the diode board and voltage regulator.
  • Bolts right on and wires up simply.
  • Original alternator/engine cover fits over the alternator with no alterations required.
  • Designed and manufactured to modern OEM specifications.
  • For ALL Moto Guzzi 1973-95 with Bosch or Saprisa Alternator (AC) Charging System, see Part # EDL450-AltKit105
