The Suzuki VX800 is a shaft drive V-twin street motorcycle manufactured by Suzuki.

The VX800 was designed at U.S. Suzuki's Design Studio in Brea, California from 1986 to 1989, and produced in the years 1990 to 1997. Lackluster sales in the United States brought the model to an end in 1993, the European version was produced until 1997.

Variations

There were four variations of the VX800:

  • the Japanese version featured a slightly shorter frame.
  • the European version was equipped with the pre-production 75-degree crank pin offset for smoother operation at high engine speeds.[1]
  • the American version was offered from 1990 to 1993 only. It was equipped with the Intruder's 45-degree crank pin offset as American Suzuki tests riders claimed the 75-degree crank offset made the engine feel dull and lifeless at US speeds. It also makes for a more charismatic exhaust cadence. American Suzuki also requested that the overall gearing be lower for better acceleration. The USA version has a secondary reduction of 1.133, where other markets are 1.096.[1]
  • the California version was the same as the USA version, but with additional anti-smog equipment.

Engine

The engine for the VX800 was derived from the Intruder 750, with a 3 mm larger bore to increase displacement, and larger 36 mm carburetors replacing the 34 mm units. The addition of a back torque limiting clutch, similar in operation as the VS1400 Intruder.[2]
