Overview

Suzuki GSX 750S3 Katana

Suzuki created the 750cc version for people who liked the look of the larger edition but wanted something not as bulky.  An upgraded model was released in 1982 (the Mark II) and then in late 1984 came the final version, the Mark III. While the Mark III still had the the overall design look from previous generations, the engine was a new 16-value unit taken from the forebearer of the GSXR, the GSX750E.  The new engine offered right around 84 bhp and the Mark III came with upgraded suspension both front and rear. The Mark III was also more comfortable due to a lower seat height and higher handlebars, which reduced the stretch to the grips and resulting knee bend. And last but not least (no pun intended) weight was also reduced by 16 kilos. All the changes resulted in a bike which was a big improvement over the previous version and also handled better than the UJM Suzuki GSX750. Of course the tech improvements weren't the only changes that put the 750se on a lot of wish lists.  The look of the bike caused a big reaction with a multi-toned paint scheme that was a big change from the all silver 1000 version.  And perhaps most noticeable of all was a new all black fairing which included a retractable/pop-up headlight. As the folks as Two Wheels wrote, "the katana looks like it's going fast even when its barely moving but so do a lot of bikes. The thing about the 750SE Katana is that it looks like its on its way to future while others are just treading water in the present." Source:
