Suzuki GSF 1250 Bandit S 2011 — Specifications

Can you really kill a myth without betraying it? That's the question Suzuki must have asked itself when retiring the venerable air-and-oil-cooled SACS engine, a powerplant whose roots reached all the way back to the 1986 GSX-R 1100. For over a decade, that engine was the soul of the Bandit lineup, their sonic and mechanical signature. With the Suzuki GSF 1250 Bandit S, the Hamamatsu manufacturer turns the page, switching to liquid cooling, electronic fuel injection, and Euro 3 compliance. A shift in philosophy more than a simple displacement upgrade.

Beneath the fairing, the inline four-cylinder gains 98 cc over the old 1157, bringing total displacement to 1255 cc thanks to a longer piston stroke. The on-paper result remains modest in outright power — 98 horsepower at 7500 rpm — but the real gains lie elsewhere. Torque climbs to 107.9 Nm at just 3700 rpm, a point in the rev range where most sportbikes are still asleep. In practice, the GSF 1250 Bandit S launches you through roll-ons without needing to flog the tachometer. The six-speed gearbox complements this mechanical generosity with clean shifts, and the fresh-air injection into the catalyzed exhaust keeps legislators happy without smothering the engine's character. Top speed on the Suzuki GSF 1250 Bandit S sits around 230 km/h, an honest figure for a sport-tourer of this size.

The chassis, for its part, saw no revolution. The tubular steel double-cradle frame retains its architecture, but the tubes gained diameter for a 10% increase in rigidity. A reasonable compromise that comes at a cost on the scales: 250 kg wet, this is no featherweight. By comparison, a Yamaha FZ1 Fazer of the same era came in roughly fifteen kilos lighter with more power on tap. The 43 mm telescopic hydraulic fork and rear monoshock get the job done without any particular brilliance — adequate for spirited touring but a bit overwhelmed when the pace picks up on twisty roads. The braking setup, with its twin 310 mm front discs squeezed by four-piston calipers, proves adequate without being sharp, and ABS was still offered as an option on this 2011 model year.

The adjustable seat at 790 or 810 mm opens the Bandit to a wide range of rider builds, and the 19-liter tank allows for decent range. For those wondering about the Suzuki GSF 1250 Bandit S's fuel consumption, expect between 5.5 and 7 liters per hundred kilometers depending on throttle hand temperament — a reasonable appetite for a big inline four. The price of a new Suzuki GSF 1250 Bandit S stood at 8399 euros, a figure that placed the Bandit among the most affordable sport-tourers in its class, well below a Kawasaki Z1000SX or a Honda CBF1000.

That is precisely where this motorcycle's strength lies: it doesn't pretend to be a disguised sportbike or a premium GT. The GSF 1250 Bandit S is aimed at the pragmatic rider — the one who wants a torquey engine to devour daily commutes and weekend rides, decent seat comfort, and a reasonable maintenance bill. It won't make anyone dream on a poster, but it will serve proudly anyone looking for a reliable tool rather than an object of desire. Suzuki traded the raw charm of the old air-oil cooling for a cleaner, more efficient engine. Romance loses out, reason wins.
