Suzuki 250 SB 2005 — Specifications

In 2005, Suzuki had a problem to solve: how to offer an authentic sporting experience without the price and complexity of a 600 four-cylinder? The answer was this 250 SB, a concentrate of miniature engineering clearly aimed at the novice rider or the enthusiast of small displacement engines. Its 249 cm³ inline four engine, fed by carburetor, delivered 28 horsepower. It’s far from the grand scale madness, but that’s the point: this refined engine needs to be exploited, to be revved to extract the best from it, thus offering valuable mechanical education.

With a dry weight announced at 119 kilograms, the SB promised the agility of a firefly. The wheelbase of 1435 mm and the back-to-back tubular frame pointed to a lively and communicative chassis, typical of machines designed for active learning. The 7.5-liter fuel tank however recalls its vocation: it’s not a road bike, but a machine for short, intense sessions, on winding roads or even on a novice track. The six-speed gearbox allows you to always keep the engine in its operating range, where it breathes.

Faced with a Honda CBR250R of the time or small twins, the Suzuki 250 SB played the card of mechanical purity. A 250 four-cylinder is a rarity, an architecture normally reserved for superbikes. Here, stripped of any pretension to extreme performance, it becomes an exceptional teaching tool. The rider learns to manage mass transfers, to anticipate braking, to feel the chassis work, without ever being overwhelmed by an intimidating power.

This Suzuki is aimed at those who want to understand the dynamics of a motorcycle before taming it. It is the antithesis of the large machine with easy torque. You have to pamper it, make it sing, accept not pulverizing the speedometers to taste the finesse of its reactions. A motorcycle for the curve aesthete, for whom sensation is more important than the number, and who sees in a small carbureted four-cylinder the last truly demanding riding school.
