Sherco SM 4.5 i-F

The 2009 Sherco SM 4.5 i-F entered the supermoto scene as a focused, competition-ready machine, building on Sherco's reputation for off-road prowess adapted for tarmac. This model year saw Sherco refining its supermoto offering, aiming to capture riders looking for a lightweight, agile package. It positioned itself directly against established European rivals in the supermoto segment, such as the KTM 450 SMR and Husqvarna SM 450 R, offering an alternative with a distinct character.

At the heart of the SM 4.5 i-F is its potent 448.6 ccm (27.37 cubic inches) single-cylinder engine, designed for snappy throttle response and strong power delivery across its rev range. This motor, coupled with a remarkably low dry weight of 109.0 kg (240.3 pounds), promised an impressive power-to-weight ratio crucial for supermoto riding. Fuel capacity stands at 7.50 litres (1.98 US gallons), which, while modest, is typical for a machine primarily intended for shorter, intense rides or track days rather than long-distance touring. The electronic fuel injection (i-F denotes "injection-fuel") system ensures consistent performance and easier starting.

Riding the Sherco SM 4.5 i-F reveals its supermoto DNA. The ergonomics are distinctly aggressive, favoring an active riding style. The seat height, at 880 mm (34.6 inches) at its lowest adjustable setting, places the rider high, offering excellent visibility and leverage over the front wheel. This upright stance, combined with wide handlebars and a narrow chassis, facilitates quick direction changes and precise control, essential for navigating tight corners and executing slides. The suspension components are typically high-spec, tuned for responsive handling and absorbing bumps on varied surfaces, from smooth asphalt to rougher urban environments.

The Sherco SM 4.5 i-F is clearly aimed at experienced riders seeking a no-nonsense supermoto for track days, spirited backroad carving, or even a unique urban commuter for those who appreciate its raw, engaging character. Its lightweight design and powerful engine make it a formidable tool for skilled hands. It's not a motorcycle for casual cruising; rather, it’s a specialized instrument for those who demand precise handling and direct feedback from their machine. Its competitive specifications and focused design make it a compelling choice for supermoto enthusiasts.
