What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1990 BMW K1, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
FUEL TANK DEVELOPED VERY LARGE LEAK AND DRAINED COMPLETELY IN LESS THAN 2 HOURS. ACCORDING TO DEALER THIS IS NOT AN UNUSUAL OCCURRENCE FOR TYPE OF BIKE AT 10 YEARS OLD. LUCKLY I DO NOT HAVE ANY IGNITION SOURCES IN GARAGE SO NO FIRE RESULTED. LEAK BEGAN AFTER PLACING BIKE ON CENTER STAND AFTER MOVING TO CLEAN GARAGE. FULL TANK OF ~5 GALLONS OF FUEL WAS EVENTUALLY SPILLED. TANK IS ALL ALLUMINUM. MAIN LEAK ON LEFT SIDE OF BIKE DIRECTLY ABOVE FUEL INJECTORS, ENGINE AND IGNITION COILS. SMALLER LEAK (PAINT BUBBLE) ON RIGHT SIDE OF TANK AT SAME LOCATION. LEAK SEEMS TO BE A RESULT OF CORRORSION FROM THE INSIDE OF THE TANK OUT, POSSIABLY FOLLOWING WELD OR FOLD IN METAL. IF FAILURE OCCURRED IN CLOSED GARAGE WITH IGNITION SOURCES FIRE/EXPOLSION COULD RESULT. IF FAILURE OCCURED ON ROAD FUEL WOULD LEAK ONTO RIDER RESULTING IN SERIOUS INJURY IN FIRE. BIKE IS COMPLETELY "STOCK" AND UNMODIFIED. NO ACCIDENTS AFFECTING TANK IN HISTORY OF OWNERSHIP, HOWEVER REAR OF BIKE DAMAGED IN ACCIDENT IN 1991. TANK CURRENTLY REPAIRED WITH "JB WELD" AND I AM RESEARCHING OTHER REPAIR OPTIONS.*AK
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
