The Intruder line started life in North America with the Intruder 700 and the Intruder 1400, which was actually a 1360cc machine. The smaller version was designed to be small enough to escape the projected 45% US import tariff on imported bikes, while the larger version was designed to take on the Harley 1340cc Evolution models as well as Japanese bikes like the Kawasaki Vulcan 1500.
The US tariff, when passed into law, actually set the import limit at 750 ccs instead of 700. So Suzuki soon bumped the Intruder up to be a 750, which it continued to produce until 1991.
For the 1992 model year the small Intruder became an 800 (technically an 805), with a larger engine, a larger radiator, and larger forks to go with the extra engine. The model would continue in this form until 2004, with the only change of note being that Suzuki started painting the engine black in 1999.
For the 2005 model year Suzuki decided to re-launch all their cruisers with the “Boulevard” name in an effort to make the name less off-putting to conservative American cruiser buyers. The slender, sporty VS Intruder 800 and VS1400 Intruder became the “Boulevard S50” and “Boulevard S83” respectively, their cubic centimeter names being replaced with the engine displacement in cubic inches.
Other changes to the VS800 included straighter bars with longer risers; the addition of four-way flashers; a one-piece seat; smaller turn signals; the deletion of the sissy bar; and the addition of a plastic fake air cleaner on the side of the engine (to hold the tool kit formerly stored in the sissy bar). But mechanically they are the same, and parts can be swapped between the Intruder 800 and the S50. The exception is that fake air cleaner, which screws into threaded holes in blocks cast into the cooling fins on the cylinders, which the Intruder 800 did not have.
As a side note, the VX800 standard/ naked sportbike was produced and sold in the US from 1991 to 1993. It used the same engine as the VS800 Intruder, only with a vacuum operated fuel pump instead of the Intruder's electric one. The rest of the bike is totally different, but the engines interchange.

Transmission
All Suzuki Intruders are powered by either a 4 or 5 speed transmissions mated to a shaft drive which delivers power to the rear wheel. Starting in 1991, the VS1400 platform received the 5 speed transmission in most European countries. In the US, this new 5 speed transmission debuted in the 1997 models, and in 1996, Canadian models were equipped with the same transmission. The

Rim/Wheels
Cast rims aka "Snowflake" rims were available as an option on the 1985 through 1987 VS700 (US Models) and VS750 (Rest of the world) standard rims were Wire Spoke; 1989 VS800 got 21" front rim/wheel combo that lasted until the 1999 model year. 2000 through 2009 VS800/S50 Boulevard run a 19" front 15" rear combination/. Both the 19" spoked/cast rims & the 21" spoke front rim from the VS700/750/800/S50 are a direct fit for the VS1400/S83, through ALL model years.
Special features
In 1990 a
MAP boost sensor was added to the VS1400 model to increase highway mileage. This correlated to a change in the
ignitor unit, which went from a two socket 4/6 pin configuration, to a 4/9 pin configuration, with the left/right orientation of the two sockets reversed.
