Suzuki GSF600 Last Samurai Is Fantastic in so Many Ways, Performance Matches Great Looks

Once the Suzuki GSF600 had been taken apart, Tossa R cleaned up its main skeleton and did away with the stock subframe. The rear framework was replaced with a custom alternative, and various electronics got stashed in between the tubes. They’re hidden out of view by handmade plates, which encase the subframe’s underside and flanks. Up top, we notice a rad black leather seat with gold stitching.

A full suite of LED lights illuminates the rear end, while the license plate is placed nice and low on a swingarm-mounted bracket. Speaking of the swingarm, it is a replacement unit 130 mm (5.1 inches) longer than the stock part, mated to the rear three-spoke hoop of a Suzuki GSX-R. The rear suspension hardware has been thoroughly rebuilt to suit the updated geometry.

Up front, we still find the conventional forks that came from the factory, but they were revamped and lowered to get the motorcycle’s stance just right. There is a rad LED headlight from Doxmall attached to the upper forks, along with a downsized front fender lower down. In the cockpit area, you’ll come across a bespoke CNC-machined top clamp flanked by clip-on handlebars.

The clip-ons are outfitted with snazzy grips and underslung bar-end mirrors, yet the overall look of the cockpit is delightfully minimalistic. Asen blessed the Bandit’s brakes with a comprehensive overhaul, as well, installing fresh rotors all-round. Turning his attention to the powertrain, he gave the engine a once-over before throwing some fresh plumbing into the mix.

We still find the GSF600’s stock headers, but they’ve been heat-wrapped and mated to an SC-Project muffler via a custom mid-pipe. The OEM carburetors are still in play, having benefited from an invigorating rebuild to keep things running optimally. Tossa R’s custom treatment saw the oil cooler revamped, as well, so as to prevent the engine internals from ever getting too toasty during spirited rides.

To take the conversion across the finish line, Asen came up with a breathtaking color scheme we can’t get enough of. On the one hand, the frame was finished in a stylish burgundy hue that’s also echoed on the rims, but black is the predominant color everywhere else you look. Gold makes an appearance on the brake calipers, as well as in the form of Suzuki tank graphics.
