It would be easy to assume that the engine in the XJ550 was just a destroked 650, but that ain’t fair. It was almost an all-new design, with a 6-speed transmission, chain final drive, and a new cylinder head with Yamaha’s YICS system that enabled 50+ mpg fuel consumption. It was a solid mid-sized motorcycle with a love it or hate it front fairing.
The XJ was equipped with lots of features that were typically found on bigger bikes, like a sidestand safety cutout, adjustable front brake lever, self canceling turn signals, and more. For more information on the XJ550, check out this profile from Motorcycle Classics.
