Suzuki unveils GSX-8T and GSX-8TT

Suzuki are set to join the retro naked bike category that’s currently occupied by the likes of the Kawasaki Z900RS, Yamaha XSR900, Triumph’s Modern Classics, the Benelli Leoncino, and most of the Royal Enfield range.

The ‘GSX-8T’ and ‘GSX-8TT’ are new models, using the engine, frame, brakes and suspension from the current GSX-8S naked, but with classically-inspired features, like a circular headlight, re-shaped tank and unique seats. Both bikes are due for an Australian release later this year.

Retro, but not too Retro

Suzuki says styling for the 8T and 8TT was guided by three key concepts – timeless, innovative and passionate. Unlike the Triumph Bonneville family or Royal Enfield Interceptor 650 and Continental GT 650 that are “true” retros, Suzuki’s creations utilise a “modern design sensibility” to pay homage to past models without directly copying them. The T500 and GS1000 from the 1970s have been quoted as inspiration for the new models, with the 'T' suffix for the GSX-8T referencing the T500’s ‘Titan’ nickname. For the GSX-8TT, the second ‘T’ is said to stand for ‘Timeless’.

Design features common to both models include the fuel tank, radiator shrouds, bar-end mirrors and the aforementioned headlight. At 16.5 litres, the fuel tank is 2.5lt larger than that used on the GSX-8S, while the bar-end mirrors are a first for Suzuki.

The GSX-8T has gold forks, while the GSX-8TT runs black forks. The GSX-8TT also adds a bellypan and headlight fairing that’s been compared to the GS1000S, but its squared-off headlight surround is more reminiscent of the Kawasaki Z1000R Eddie Lawson Replica from the early ’80s.

Seat designs differ, with the GSX-8T featuring a ribbed top on its tuck-n-roll seat, while the GSX-8TT has a flatter, racier design, with a subtle two-tone finish and contrast stitching.

For some markets, the GSX-8 retros will be available in a range of colours, but Australia will only receive one option for each – Candy Burnt Gold for the GSX-8T and Glass Sparkle Black for the GSX-8TT. The former has black rims and satin silver radiator shrouds, with red rims and black shrouds on the latter. The GSX-8TT also features red and gold stripes on the tank and fairing.

Twin Power

The GSX-8T and 8TT use Suzuki’s 776cc parallel twin that’s compact, yet powerful. Outputs of 61kW at 8500rpm and 78Nm at 6800rpm are unchanged from the GSX-8S and mean the 8T/TT pair are not LAMS approved. The engine’s 270-degree crank ensures a responsive feel to throttle input, while a cross-balancer reduces vibration. The 2-into-1 exhaust system, contained under the engine, is said to have an enhanced note and features a stainless-steel cover.

Tech that enhances the performance and usability of this DOHC twin includes a ride-by-wire throttle, Low RPM Assist function, Suzuki’s Easy Start System, three-stage traction control (that can also be deactivated) and drive modes – all under the umbrella of the Suzuki Intelligent Ride System. The three selectable drive modes – Comfort, Basic and Active - alter the throttle response, with Active the sharpest, Basic providing a more linear response and Comfort the softest response, to suit two-up and wet weather riding.

The transmission is a six-speed, and comes with the Suzuki Clutch Assist System (SCAS) and bi-directional quick shifter for smoother and easier gear changing.

The drivetrain sits in the same steel frame with a bolt-on subframe and aluminium swingarm as the other models in Suzuki’s 800 range, with KYB suspension front and rear. The USD forks offer 130mm of travel, and while rear travel isn’t listed, the link-type monoshock does offer preload adjustment.

For braking, twin 310mm front brake discs wear radially-mounted Nissan four-piston calipers, while the 240mm rear disc uses a single-piston caliper, with standard ABS. Wheels are 17-inch front and rear, with the tyre package consisting of a 120/70ZR17 hoop at the front and 180/55ZR17 at the rear.

Tech and Ergos

While the temptation may have been to go with analogue gauges for a retro model, the GSX-8T and 8TT run the same 5-inch TFT colour screen as the GSX-8S. This prioritises the essential information, with bold revcounter, speed and gear position displays.

Secondary information includes fuel level, riding range, two trip meters, engine temperature, drive mode, traction control mode, a clock, voltmeter and service reminder. Along with Day and Night modes, the TFT screen also the ability to show alerts and warnings as pop-ups.

A USB-C socket is standard, as is a lightweight, compact battery that’s said to outperform conventional lithium-ion batteries.

Lighting is LED all round, including the “mono-round” headlight that was inspired by the flat-bottom headlights used on Suzukis from the 1960s and ’70s.

Ergonomics are neutral, reflecting the GSX-8S origins, with an upright riding position and comfortable reach to the handlebars. The compact parallel twin allows the rider to sit closer to the centre of the motorcycle for better control, with consideration given to pillions in the seat height and footpeg location.

The different seat designs across the two models results in different seat heights, with the GSX-8T at 815mm and the GSX-8TT at 810mm. Weight varies fractionally, too, with the GSX-8T tipping the scales at 201kg and the GSX-8TT at 203kg. Both are broadly in the range of the GSX-8S.

Late 2025 Arrival

The GSX-8T and GSX-8TT are due to arrive in Australia in Q4, 2025, with the 8T to be priced at $17,990 ride away and the 8TT at $18,990 ride away. A two-year warranty is standard, which extends to three years with regular servicing at an approved Suzuki dealership.
