The Ultimate Alternator Charging Kit for your BMW 2 Valve AIRHEAD 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.

Application Table
  • Original Equipment, New, Modern charging technology updates the BMW R Airhead original, under-performing 20 amp (max) alternator and rectifier.
  • The critically important higher amperage output of this system at low engine RPM's allows use of lighting, heating and other accessories to be used without discharging the battery or overloading the original charging system.
  • 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
  • For BMW 1970-1976 w/105mm stator frame use Pt # EDL450-ALTKIT105
  • The Total Maximum Rating of the system is 32 Amps or 450 Watts with a smooth measured increase in power:

29 Amps / 400 Watts @ 5000 RPM
25 Amps / 350 Watts @ 3000 RPM
20 Amps / 280 Watts @ 2000 RPM

We strongly recommend the replacement of the Oil Seal when you replace the Rotor:
