Frequently asked questions
What should I check when ordering a replacement alternator for the BMW R 1250 GS?
Match the exact engine code and the model year of your R 1250 GS K50, as alternators differ in output (amps) and mounting. Check whether the pulley is included or needs to be transferred.
Is a remanufactured alternator a good option?
Yes – remanufactured alternators are tested to OEM specs and are often significantly cheaper than new. They're a reliable and economical choice for most vehicles.
