Motorcycles of the ’60s, ’70s, and even the ’80s gave any reviewer real meat to sink their teeth into. Engines would overheat, clutches would drag or slip—or both at once. Smoke would pour from the exhaust pipe of a four-stroke on over-rev. The forks always contained the wrong amount of stinky whale oil that invariably needed changing, and the spring rate was never right. Swingarms flexed, tires slipped, and quite a few bikes were really, truly, god-awfully bad.
