From a press release issued by Suzuki Motor USA, LLC: :

Immediately highlighting the R element of the new GSX-8R is its full fairing, wind tunnel-tested to increase aerodynamic performance and provide weather protection for the rider. Bold 8R logos adorn the side panels, while fairing-mounted mirrors also aid in reducing drag.

Perched in the middle of the angular face is the recognisably GSX series stacked LED headlight, topped by an LED position light. The rear combination light is also full LED, as are the indicators.

At the heart of the new GSX-8R is the 776cc parallel twin engine – which it shares with the GSX-8S – with its long stroke and 270° crankshaft design providing an abundance of low-down torque, usability, and flexibility, while a free-revving nature comes from a DOHC and four valves per cylinder. Peak torque is 78 Nm, delivered at 6800rpm, with peak power of 82.9PS coming at 8500rpm.

The 270° crankshaft also provides a power delivery, character, and rumble reminiscent of Suzuki’s much-lauded V-twin ranges, while a patented cross balancer design ensures a smoothness, as well as aiding in a compact, lightweight engine design.

A two-into-one exhaust system with dual-stage catalytic converter keeps the 8R conforming to Euro 5 emissions standards, and ends in a short, underslung silencer further enhancing the compact, slimline look.

All of that is housed in a steel frame engineered for direct handling characteristics. Those handling characteristics are further enhanced by low, forged aluminium handlebars that provide positive control and a sporty riding position, placing more of the rider’s weight over the front wheel. Bolted into the rear of the steel frame is a lightweight aluminium subframe and lightweight aluminium swingarm,

Dealing with the increased weight bias towards the front, Showa provides the suspension, with SFF-BP* (Separate Function Fork – Big Piston) inverted forks and monoshock in the rear. Mounted radially to the forks are Nissin four-piston calipers, providing stopping power by biting 310mm discs. Tyres are Dunlop Roadsport 2s.

Aiding rideability, usability, and flexibility is a suite of electronic systems that includes a bi-directional quickshifter as standard, three selectable engine power modes, and three selectable traction control settings, plus the ability to disengage the system entirely. There’s also Suzuki’s low RPM assist and easy-start function.

The GSX-8R’s settings are easy to navigate via a single rocker switch on the left-hand handlebar, with the information displayed clearly on a colour 5” TFT screen.
