1979 Yamaha 1100 Special Views
The XS Eleven made its debut in 1978 as the largest capacity Japanese superbike then currently in production. It featured dual front disc brakes, a rear disc brake, shaft drive and cast wheels. A factory custom styled XS Eleven Special was released alongside it in 1979. Both models were superseded by the 1982 XJ1100 Maxim which used the same engine. The XJ1100 Maxim was only built for one year, before being phased out. In Europe, the XS Eleven differed from the North American model by having a larger gas tank (6.3 gallons vs. 5.3 gallons), a lower handlebar and longer exhaust pipes. The European market also featured the 1.1 Sport and Martini.
In 1979, Yamaha followed the growing trend of offering a factory custom version of the bike, called a Special by Yamaha. Pullback handlebars, a stepped seat, a smaller, fatter rear wheel, a smaller capacity tear-drop gas tank, fully adjustable suspension, and altered frame created a factory custom, forerunner of the modern cruiser. The XS Eleven Special sold well despite complaints about the poor ergonomics. What that translates to is a bike with an awkward riding position but generally excellent road manners. In fact, most of the things that irritated this staff in the way the bike rode and handled could be traced to the handlebar, which, although certainly as trendy as disco dancing, was not what the ergonomics doctor ordered for precise, comfortable control.

The Midnight Special includes all the good features of this XS1100 family, plus some items that are elite onto itself. For instance, the Unified brake system. This braking system was developed by Yamaha to stop a motorcycle more easily and conveniently. Utilizing a triple disc arrangement, two at the front with a single at the rear, the Unified Brake System has a proportioning valve (P-valve) fitted in the hydraulic brake, line that links the left front and the rear brake calipers. The P-valve is connected to the master cylinder by a small metal brake line.
