The 1994 VR 1000 was the first pure racing motorcycle Harley-Davidson ever built. Every other Harley racer, from 1915 through 1993, had been a modified production machine. The VR was purpose-built from the ground up.

Milwaukee has never been comfortable with the concept of purebred competition machines. Eighty years earlier the founders had 'been dragged mumbling into the racing game, convinced of its necessity only after Indian had captivated the sporting enthusiasts of the 1910s and 1920s.

But once installed in the Milwaukee hierarchy, the racing department proved itself a continuing resource of team spirit and public good will. People rode their motorcycles to the races, and supported their favorite riders and manufacturers.

Harley-Davidson had maintained its support of dirt tack, the traditional American fairgrounds racing, and built a few XR 1000 production-based roadracers. But nothing on Milwaukee's menu suited the demands of Superbike racing in the 1990s. At the upper outposts of "street bike" competition, the track-wise roadsters weigh 375 pounds (170kg) and produce 150 horsepower. Handling and braking factors are tuned to millisecond response margins. All of which is enormously expensive to achieve.

With some money in the bank,

Harley decided to build its second eight-valve racer, with an American engine, chassis and brakes. Engineer Steve Scheibe headed the team, and called in experienced help from NASCAR and Indy Car racing. The project took five years and produced a double-overhead-cam, 60-degree V-twin, with 4-valve heads, Weber-USA electronic fuel injection and liquid cooling. Power went by gear to a multi-disc dry clutch and through a 5-speed transmission.

The first bikes used a Penske inverted fork and Wilwood six-piston brake calipers. The road model carries an Öhlins fork with titanium-coated stanchions. The body work is constructed of carbon fiber, and the factory listed the dry weight at 390lb (176.9kg). The production schedule was set for 50 copies of the VR 1000, the price of each listed at $49,490.

The VR first appeared on the racetrack for the Daytona Superbike race in 1994.

There were few illusions about the early chances, and teething problems were anticipated, but the motorcycle handled remarkably well. Top speed was not at the level of frontrunners, though rider Miguel Duhamel turned in good results on some of the tighter circuits. Results for the 1995 season were disappointing, and rider Doug Chandler had difficulty coming to

terms with the machine. National dirt track champion Chris Carr was also on the team and showed a quick learning curve.

Rumors circulated during the offseason that management disputes in Milwaukee cast doubts on the future of the VR 1000. The factions split as they had a half-century before; the economic rationale perceives big-league factory racing as large expense versus small return. The sporting enthusiast segment says racing pays huge dividends in public relations, and puts the company logo on television. And wins hearts and minds.
