I used to work on just about any brand machine, back in the late 60's-early 70's, and that was not limited to only motorcycles......cars too.
Most of the European electronics back then, ie, ignitions and charging/lighting systems, were dismal failures.......especially on Jawa/CZ bikes....not much better for the Brit machines, nor the German & Italian built.
The mechanicals of the Euro bikes were of high quality, and had they been equipped with more reliable electronics, Japan wouldn't have so handily trounced those Euro manufacturers, IMO.
Spanish built off-road bikes, (Ossa, Montessa, Bultaco) created some fantastic, early day solid state ignitions, and those were highly reliable.
The rest of the bunch, pretty much used points and condensers, and that included the American built bikes and cars as well.
Japanese built machines also used points/condensers at first, however, they were fairly reliable, plus the ignition/wiring/charging systems were built to last a spell.
Almost overnight, the Japanese "big four" catapulted racing machine development, and rapidly became the industry's leaders.
American industry (in general) stood by and ignored the Pacific Rim's challenges...... all while looking down their noses at the enormous potential profits contained within the unbridled, off-road motorcycle racing phenomena, which had so tumultuously migrated across the Atlantic pond.
Even Mexican origin companies sprang up, and tossed the gauntlet, though, their products were only manufactured for a short term.
Sure do wish the USA MC industry had taken the off-road motorcycle more seriously, or at least had made a concerted effort to compete.
