Overview
Yamaha XJ 650 Maxim
Maxim: Legend in its own time, now for the price of a song, almost.
□ In 1980 the Bright-Think Bulb at Yamaha was glowing hot enough to heat the
Great Outdoors. Yamaha delivered its basic high-wattage idea the 650
Maxim. What if, some Yamaha people had asked, Yamaha builds a high-performance
650 motorcycle and gives it "special" styling? Although other makers had dabbled
with the cruiser get-up laid over basic Japanese four-cylinder motorcycles, no
other manufacturer had made the million-dollar commitment: design a brand-new
four-cylinder, and build it specifically as a special. At Yamaha the special
became the standard.
Three years later, after the wide proliferation of special styling, it's easy
to forget what a landmark bike the Maxim was. The 650 was striking,
controversial, sensational, and wildly successful in showrooms. Succeeding
models were refinements; the 1982 XJ650J had a more comfortable cut to its
handlebar, an air-adjustable fork, and a more luxurious seat.
For stoplight aggression, the Maxim was well armed. The air-cooled, twin-cam
650 engine was a genuine mid-12 quarter-mile streaker. The engine looked lithe
and athletic too; Yamaha made it narrow by locating the alternator
piggybackbehind the cylinder block and above the gearbox rather than hanging
the works on the end of the crankshaft. The Maxim had another amazing feature
for a motorcycle touted as a high-performance piece: shaft drive.
Years later, the Maxim is a cruiser classic. Other companies have produced
bodacious knock-offs of the 650 Maxim, imitations that suffer from excess ("If
they like slightly stepped seats, we'll give 'em real split-level housing").
It's too bad the Maxim was obscured when manufacturers blanketed the market
with cruisers. Now Yamaha has decided to turn up the spot lights on the XJ650J
Maxim or is it turn on the flashing blue light? The price has plummeted from
$2999 in 1982 to $2189, and for the savings you should be able to cruise Main
Street for the next 10 years. A decade down the road, the Maxim may well be a
genuine classic of the 1980s a bright idea that stood the test of time.
